whats a standard fuel pressure for a mild H/C/I car, not only because I dont know, but im trying to figure out if I need a 1-15 or 1-30 etc. psi fuel pressure gauge, any help? thanks!
For sure the 1-50 is more accurate but no big deal you just have to focus more on looking at the 1-100psi to set your pressure. I've had both and they worked like a charm.
Mine's easy enough to read, it's 0-100. I can tell going down the road if it's at 38, 39, or 40 psi (the only settings I run, usually it's at 39 unless it's really cold or hot out).
If you're setting it under the hood with an AFPR, simply use a test guage set, they're 0-100 psi in large readable increments and plug temporarily into your schrader valve to get a reading.
