im looking at buying a fuel pressure gauge and ive seen 0-15 psi and 0-100 psi gauges, i was wondering what is a normal fuel pressure for a 305 tpi engine. i was also looking at a trans temp gauge, anyone know normal operating temp of a stock 700-r4?

 

0-15PSI--> carb motors
0-100PSI--> Fuel injected
I think fuel pressure is in the neighborhood of 42PSI

 

The Autometer FPG 0-100 PSI is what you need for a TPI engine.
Check Summit / Jegs for similiar gages. Stock pressure is 36/38 at idle & 43/47 PSI at WOT. This is a permanent mount under the hood installation ONLY. Also this not a test type gage.
