Hi Folks, I'm finishing up the fuel lines for a BPE 347 FI system. Could I install the F5's 'complete kit' FPR, inline with the return AFTER the built-in Sniper FPR? I like the readable gauge on the standalone FPR. Can I simply open up the external pressure regulator such that it won't impede the Sniper's pressure but will read and display the Sniper's fuel pressure? And yes, I understand the Sniper does allow external FPRs as long as you plumb the fuel lines appropriately to the Sniper in such a case. I just want to use the Sniper's FPR but have a nice gauge to read it... unless there's a better solution?

Could you just install a fuel pressure gauge on a T adapter inline with the feed into the Sniper? As in, find one of these and install inline (with correct genders for your application)?

No, you would only be reading whatever pressure there is in the return line. Hopefully it is free flowing enough that there is little to no pressure. Brandon has a better idea. You may be able to use that gauge and just move it to the Tee.

See? That's one of the many things I love about this forum: You guys can make the sight of the forest clear through the trees. :D
Here's what I went with to go right on the output port of the Sniper: https://www.summitracing.com/parts/sum-220675b
Be sure you install the pressure gauge on the inlet side of the Siper, not the outlet.
Lots of good info on the Holley forums:
