The trick to getting these socketless hoses on is the following:
1. Buy the tool that holds the connectors
2. Buy the grease that is recommended for this type of socketless hose
3. Heat up the hose ends in boiling water until they are soft. I'm talking
about 5 to 10 minutes.
4. Liberally apply the oil to the socket end and inside the socket hose
5. Press the hose onto the connectors. If they are not easily sliding

I installed a Permacool oil filter relocator kit because I really don't
enjoy changing my oil. Also, I don't like the placement of the current
oil filter. Usually, I reach in through the driver's side wheel well and
pull out the filter. But always, because the filter is inverted at a downward's
angle, oil always spills out and if you're not careful pulling it out,
you can drop it onto the skid plate. Sometimes it can be a pain and I
was getting tired of "sometime".
The Permacool filter relocator kit will enable me to do two things: relocate
the filter for easier access as well as allowing me to use a larger filter.
Of course, you don't have to install a relocator kit to use a larger filter,
but this just makes it that much easier. In conjunction with using Amsoil
motor oil and Amsoil's large filters, I can run this oil for up to 25,000
miles or 1 year and only need to change the filter every 6 months (or
12,500 miles). I'll save money in the process too.
As is the case with my oil
pressure gauge writeup, special thanks again goes out to Jsharp (Jim).
Jim's advice was especially needed for this writeup.
if you're planning to do the oil pressure gauge mod and this mod, it's
best to do the oil pressure gauge mod *first*, but do not install the
sender. It will only get in the way of much needed space.
Step 1: Prep Work
Remove the skid plate by removing the seven 12mm bolts. You may need an
extension to access all the bolts. Now drain your existing oil, remove
the oil filter as shown in my oil
change writeup, and then clean off the surface of the oil filter area.
After all the oil has drained, bolt down the oil plug.

2: Understanding How The Parts Fit Together
Refer to the diagram below. In short, there are several adapters, hose
ends, and hoses that need to be connected together. These parts will be
connecting the new oil filter mount and the engine adapter itself:
As you can
see here, you will need to connect adapters to the actual Engine Adapter
itself and then connect Hose Ends to the adapters. On the other end, it's
the same process, but its best to just connect the hoses to the hose ends
first. Once done, you can connect the hose ends to the adapters and then
get started on assembling your relocator system. More on that later. But
first, you will need to create a sturdy bracket for your oil filter mount
to mount it inside your engine bay.
Now before you ask, I'll pre-empt you: While it would be much easier to
just bolt it inside the wheel wheel, I just can't stand the idea of having
the filter so visible and accessible to the idiots of the world. All it
takes for some punk to ruin your engine is to unscrew that filter and
let you drive along your merry way.
Step 3: Creating a Bracket
After consulting with JSharp, I decided to copy his right angle
bracket idea. While I was not able to find an identical bracket, I did
find something very similar and very sturdy in Home Depot's fence aisle.
It's a steel Stanley fence bracket. It even has pre-drilled holes.
First, remove the battery by unhooking the battery cables. Move the battery
and the tray out of the way for more room. Next, eyeball a good location
for your bracket. For mine, I wanted to utilize at least one of the holes
with my bracket's holes. I aligned the pre-existing hole and then I made
some cut marks with a Sharpie in the bracket itself.
the space where you'll mount the bracket. Notice the battery has been
mark on bracket denotes a cut line. The bracket will need some serious
grinding to make it fit
the last point, the battery's weight is reinforced by some "wavy"
metal that is welded onto the inner body itself (see pic above). These
get in the way of the holes. Thus, you'll have to trim some of your bracket
away in order to allow the bracket to fit underneath the wavy support
To do this, there was quite a bit of trial and error---and a lot of cutting
and grinding. I finally used my bench grinder to grind away at the bracket
until it looked like the pic below.
Next, in order to make sure the bracket would stay in place and support
the weight of the oil filter and mount, I needed to drill another hole
in the metal. So place your bracket in place and then stick the bolt through
and secure it at the other end. Go to your fender wheel well and then
use your Sharpie to mark the hole. Use a drill press (best) to drill a
nice, clean hole. Also regarding the bracket itself, the bracket length
is pretty long and so it needs to be trimmed, but do this after you've
mounted the oil filter mount onto the bracket in the next step.
is a shot from the wheel well. The bolt protruding from hole (2) is
the only bolt than can be fitted through the test-fitted bracket (other
side). You will have to mark a hole (1) with a sharpie and drill that
out from the bracket
drilling the hole, test fit holes 1 and 2 with a bolt and nuts on
the other side. Note how the top edge and left side of the bracket
has been seriously grinded to fit all the waves and curves inside
Step 4: Modifying the Orientation of the Oil Filter Mount on the Bracket
Because I want to use the larger Amsoil SDF-34 oil filter, I
needed to offset the filter at an angle. Otherwise, mounting it perfectly
vertical makes the bottom of the oil filter hit the frame rail.
Like the filter bracket itself, I wanted to utilize at least one of the
stock holes on the bracket itself and the oil filter mount. See the diagram
above, the oil filter mount does not sit parallel to the bracket---it
sits at an angle. Keeping with the "utilizing one hole" principle,
I secured that one hole into the bracket's hole with a nut and bolt and
then used a Sharpie to mark the second hole for drilling. After marking,
remove the oil filter mount and take your bracket to your drill press
for drilling. Test fit and then move onto the next step.
fit without the filter

the radiator hose
5: Connecting the Engine Adapter Parts and Hoses
First, install the rubber O-ring to the underside of the engine
adapter. Don't forget this very crucial step. Next, wrap about 2-3 wraps
of teflon tape around both straight adapters. Use a crescent wrench to
wrench in these adapters into the engine adapter. Next, wrap about 2-3
wraps of teflon tape around the exposed ends of the adapters that you
just mounted. Finish by wrenching down the vertical hose ends to them.
socketless hoses, do a test fitting by running the hoses from end to end.
Take the measurement and then
cut about an inch or two more just to be safe. My hoses ran around 16
to 17 inches.
After figuring out the proper length of hose, liberally douse the hose
ends and the inner portion of the hoses with Aeroquip's lubrication fluid
or 5W-30 oil. Insert the hose over the hose ends and get ready for the
time of your life---these son's-a-b###hes are TOUGH to get on! I could
not get these hoses completely flush with the hose ends. Nevertheless,
the connection seems pretty solid. Repeat for the other hose.
side of the engine adapter is marked either "IN" or "OUT".
So for the "IN" side of the hose (engine adapter side), mark
on the other end of the hose with the word "OUT". For
the hose attached to the "IN" side of the engine adapter, mark
the other end of the hose with the word "IN". That way you easily
know on the other end, which side to connect it to.
coat and wrench down the threads on adapter (A); repeat for Hose End
(H). Secure hoses (B) and try to avoid gaps (G).
the appropriate hose ends "IN" and "OUT". Pay
attention to this step or your engine may be severely damaged if you
don't follow the instructions!

repeat this as warning: DO
NOT CONNECT THE "IN" SIDE OF THE ENGINE ADAPTER TO THE "IN"
SIDE OF THE OIL FILTER ADAPTER AND VICE VERSA!
attaching the engine adapter side hoses, move onto the oil filter mount
hoses. First, remove the test-fitted bracket and oil filter mount from
the inside of your engine bay. Next, spin off the oil filter and then
remove the oil filter mount from the bracket. Following the same process
for teflon taping and wrenching down the adapters and hose ends. The best
order and process in my opinion is to wrench down the adapters to the
oil filter mount, connect the hoses to the hoses, and then bolt down the
bracket itself (not including the oil filter mount) to the engine bay.
6: Mounting the Engine Oil Adapter and Oil Filter Mount
First, turn your wheels to the left so as to allow some more
room to access your front wheel well. Next, stick in the engine oil adapter
through the wheel wheel flap and get it to the general location of the
OEM oil filter mount. Check to see that O-ring gasket is firmly seated
within it and then screw in the engine oil adapter until very snug. Since
the hose is thick, you'll probably need to assist it while turning and
screwing in the engine oil adapter.

up towards the top and alongside the alternator. JSharp routed them behind
a wire bundle but I chose not to. Now that you have them in position,

the hose ends to it. After doing so, bolt down the entire oil filter mount
to the bracket.

7: Re-Oiling and Testing
First, fill your oil filter with motor oil and then connect it
to the oil filter mount. Of note, you may be suprised at how much oil
can be stored inside the larger filter. I was almost able to put a whole
quart in the Amsoil SDF-34 oil filter. Next, pour 5 quarts into the oil
receptacle. Check your dipstick to make sure that there is sufficient
oil within the acceptable range (marks) on the dipstick.

dealer and I would love to have your business :)
for the big moment: fire it up! If you did everything right, there should
not be any leaks. The one place where I found a leak was the oil filter
and oil filter mount. I did not have it screwed down as hard as it should
have. I guess that was years and years of "hand tightening with a
quarter twist". Here are some oily "glamor shots" of the
installation. Note the gaps between the hose ends and the hoses. They're
not huge, but not flush.
First, I must have to make a huge criticism of Permacool's customer service.
My rubber O-ring was slightly torn and I did not want to use it for that
reason. Thus, I gave them a call. They transferred me to a gentlemen who
quite bluntly stated that "we don't send out replacement parts...you'll
be able to find those O-rings at a local auto parts store". I even
offered to come down to their plant and pay for it too, but my offer was
Regarding the Aeroquip socketless hoses and hose ends, unless you have
a trick and/or incredible hand strength, don't bother because these things
are pretty difficult to get them flush with the hose ends. This delayed
and frustrated me most with this project. But if anyone knows the "secret",
please email me back. Otherwise, the quality of their products is top
notch. My advice for people who don't want to go through the time and
hassle with these products is to buy the old fashioned braided steel lines
with the appropriate connectors. It will be much faster and painless to
Turns out, they were not so easy to find. I had to go to a more specialized
auto parts store (Ernie's in Monrovia, CA). What they had to do was to
order me a pack of O-rings for which only one fit the filter mount. Hey
Ernies, you guys are the best! Those guys spent about 10 minutes trying
to find this pack of O-rings for me. Ernies will have my future business
or feedback? Email me and I'll try to get back to you. If this article
