Sunday I did this to my 99.5 : http://www.dfuser.com/Install Guid...tor Shim.pdf only I used a BB. Everything went fine. I put 100 miles over 2.5 days, and no prob. Now when I left for lunch today fuel was poooouring out the lid of the filter (around the oring).

I R&R'ed the filter (same filter) , and leak stopped, I drove 1 mile shut off-no leak, start up 5min later, no leak, drive .5 mile no leak. Shut off, 40 min later, start up, badddd leak, the oring had popped out. Then I installed new filter, drove 1 mile, shut off- no leak.

The o-ring on the old filter looked swelled, and the filter was due replacement anyway.

Did the BB FPR have anything to do with this, am I going to have this prob in another 100 miles or is the leak just coincidence.

Depending on which end of the spring you installed the BB.. You probably have TO Much fuel pressure.. More pressure than the O ring can handle. And/Or, the BB is not allowing the pressure to bleed off at Shut Down.

JMO but.. One of the pitfalls of using a BB :dunno

Sometimes it works.. Sometimes it Don't.

did you put a gauge on there to see how much pressure you had baseline vs. what you have now? I would take it out unless you know what kind of pressure youre making.

1064rg (?) I'd git that BB outa there.. until you have.. >Known<.. fuel pressure readings, from Before & After the BB.

(I've seen Filter housings Split open, from over-pressure) (purdy big bucks there)

I put the BB between spring and the piece that attaches to the fuel line.
I drove 20 miles home, and 20 miles to work, and no leaks. I will try to remove bb soon.

Right off the top, I'd say you might have compressed the FPR spring to the point where there's little, if any, regulated pressure. You may be running at the Max psi yer fuel pump is capable of ??

Drove home at lunch-20 miles no leak. Start up 2.5 hrs later- filter gasket popped out, big leak.
I removed the BB, drove 20 miles to work, no leak.
Hope this fixes it.
Thanks everyone.
