fuel pressure problem

[Vegas69]

What size fuel line did you use. Is it a returnless setup? I would think based on everything I have read that you would need at least a 1/2" supply and return line. I have not read anything about guys having problems with Ricks in tank pumps under a half tank only the external pumps.

With two posts your an expert? I have seen it and it's on in tank pumps. Regardless you return should be the same size. I don't think that's the problem here though. I'd check the basics like fuel filters for debris. I also have to question your regulator being on the return side. Finally it is possible your pump is failing. Check the amp draw vs what it shoudl be.
