FPR mod probs

[prdcustoms]

I did the FPR mod, and I just blew out the fuel filter seal. Has anyone else had this problem?
I just bought a new filter / seal, took the spring spacer out - because I don't want to blow it out again. Could it be that it was a really old seal, and I would be safe with the new one, or is this a common problem?
I'd like to keep running the mod, but I don't want to lose another 1/4 tank of fuel

Here's a bump. I'm interested in the answer too. I plan to do the BB mod this weekend without a guage. Maybe I shouldn't?

I have had the BB in my FPR shim since the first week I have owned my truck (over 2 years) and I have had no seal problems at all. I simply installed the BB and forgot about it all together. I never put a gauge on my fuel bowl to determine what PSI I had, I runs great. Sorry to hear you had complications.

I ran the FPR mod for a long, long time. 5 years I think. It was holding 68psi for ever.

Maybe I had a weak seal, I'll try to put the spacer back in.

You using a BB or a bolt or??
Have you checked the pressure before and after?
Probably just a loose or bad filter seal.
Do you use a good quality filter and does it use the old lid or come as one piece with a new lid?

First time i changed the fuel filter on my truck the seal blew out 2x on a trip. Turns out the cap I was using had the treads made wrong (cut too deep). That was with a stock pump. I would try a different filter or cap if you just replaced it.

Make sure the seal is in the cap correct as well. On my cap there is a groove cut in the flange sticking out so the seal goes into the groove and when it is tightened, it can't blow out. The seal is completely contained. Did you take the old seal out?

That seal can be put in upside down too IIRC. One way is right one way is wrong.

What pressure did you shim it too?
