Shimming the FPR means installing a BB. I'll see if I can find the link for you or you can try a search for "FPR Shim". There should be some pictures along with the instructions.

You'll need a Q-tip with the cotton removed to clean the FPR screen.

I don't how to check to the stuff Joe mentioned. I'm waiting for him to respond to you.

Here's a link to check out. It isn't the one I was thinking of, but I'm still looking.

If you have low fuel pressure, I wouldn't do the shim mod to fix it. Likely you have a weak pump, I'd fix that properly first. Also if you can get data stream check your HPOP pressure maybe.
