?? for anyone that changed fuel filters lately

[MDarrough]

I am in the middle of changing my fuel filters and realized that there was a change in the design of the separator filter on the frame.

The new one is about 1/4" longer and has an o-ring on the end with the large opening. When I tried to tighten the cap, it would not tighten enough to close the 1/4" gap between the cap and the filter housing.

Has anyone else run into this? What did you do? If I leave the gap, will it leak there?

PLEASE HELP!!

BTW - I would like to find the designer if the frame-rail filter and hang him by the cahonies!!

I borrowed this pic from another thread to show the difference.



Thanks,
Mark

Just a stupid question, but are you sure you have it in the correct way?

What i'm asking is are you putting the part with the O-ring towards the cap or inserting it into the housing first. I haven't used this new filter as of yet myself so just speculating.

[MDarrough]

Yes, definitely putting it in correctly. O-ring end in first.

I'm thinking I'm just missing something simple that I'm not doing right.

New design due to bypass reasons.Oring is supposed to help it stay in place so it doesn't allow dirty fuel to bypass whole assembly.

Ok, feeling like a doofus right now. I'm sure you thought that would be the case.

It wasn't the filter that was stopping the cap from snugging all the way down, it was the big O-ring on the cap. I lubed it good with diesel, but obviously that was not enough. So, I soaked the o-ring and the o-ring seat on the housing down with WD-40 and cranked on the cap. It finally kinda squirted into place and tightened up good. What a PITA!!

I got one of THESE FROM AUTOZONE and it sure makes it easier.

Yeah those rings are tight fitting. I bought the same tool from Advance Auto Parts. Not cheap but worth every penny if your changing your frame mounted filter.

We have a few of those at our oil change shop. They fit the 6.0 and 6.4 oil caps, 6.4 and 6.0 primary fuel filter down stairs (he uses an air ratchet on em), and the 6.4 top fuel filter.

What are the torque specks on these filters?
