Any updates on this?

 

I haven't had a chance to check the intank pump or bypass the inline yet. Performance wise, I had one of my best days yet at the track two weeks ago. My pressure doesn't go below 45ish too often. But it doesn't go in to the 60s at all. I'm going to check my fuel pressure sending unit also.
I'll keep you posted.

Well it's 6 months later and I finally bypassed the inline pump today. Before I bypassed the inline I took a drive and say 44-46 PSI. I bypassed the inline, took drive(just around the block) and saw about the pressure. At idle in the driveway, with everything hooked up, I pulled the vacume line off the FPR and saw 56 PSI.
This makes me believe its the FPR.
Agree or Disagree???
