I followed ARB's instructions to the best of my abilities and drilled,tapped,installed the bulkhead fitting. It matches up to ARB's picture pretty well.

I am still dissatified with the bulkhead fitting exit- I am concerned with the airline fitting/spring contacting the oil pan.

Just wondering what you guys have done?

Possible Solutions:

Install 90 fitting directly out of the diff
-I don't want to remove the current bulkhead fitting to install a 1/4 NPT 90 fitting out of the diff. ( I don't want to run the risk of changing the depth/position of the copper tubing- If the copper tubing gets pushed in just a little too deep, it will contact the ring gear bolts.)

-Cut blue plastic 5mm airline and install a 90 degree push fit- union (I'd rather not introduce an extra push fitting)

-Order custom airline with 90 degree fitting from Russell Performance or http://www.independent4x.com/item.jhtml?UCIDs=839915|1211871&PRID=1500990
(maybe later, don't want to spend the extra $$$ yet)

Has any one directly replaced the airline fitting with a drop in part?
I know ARB likes to use damn bspt threads- Hopefully we will get some part # posted- for some 5mm -90 compression fitting that will accommodate the 5mm blue airline, insert tube & ferrule.

I will also give ARB a call later in the day.

I just let it hit the bottom of the pan, it just barely touches it. I then put a piece of rubber vacuum line over the blue line where it makes contact. Seems to work fine for me.

Its not like the front diff. can really move, and the oil pans movement is very limeted so it shouldnt be a big deal.

Yeah,
I've already sleeved the line for added protection.


Let's see If we can find a 5mm 90 fitting or even a 3/16" fitting that will mate up to the bulkhead
So what we need is a 90 degree 5mm tube (compression) to female 1/8 Npt/bspt?

Here is a start

Strip it down to the bare 90 and use it in place of the ARB male-male nipple.
