Autometer FP gauge for 12v?

[plangone]

I'm sure many have asked this question, but I still can't find a great answer.



I'm looking to add fuel pressure gauge to nearly stock 12v truck. Maybe will add FASS type system at some point, but no time soon. I will have Autometer Ultralite Boost and EGT gauges and wanted to match when adding FP gauge. They only FP ones they have are 0-15 and 0-100. Am I better off using a 0-35 boost gauge instead, or will 0-100 be ok?

I use the 0-100psi autometer mechanical...

if everything is good on a stock truck you should be in the 20psi ballpark...

Mine is a tad bit higher than that, that's why I use the 100psi gauge.

All that to be said, you can taker up to about 45-50psi if your hot roddin' arround.
