Hey guys. I am in the process of tuning this fuel curve in my gen 1 sbc. I am using an innovative wideband that can log multiple sensor inputs. My question is, can i use a stock oil pressure sensor to capture fuel pressure. I have a suspicion that my fuel pressure may be dropping off as the car goes lean at higher rpm's. I have an extra sensor laying around from the old 3.4, i figured i could wrap some thread tape and use that stock sensor but i was worried that it may not be compatible with fuel. Anyone have any ideas?

It may work, but the downside is a potential electrical fire if the diaphragm were to fail & leak fuel everywhere.

 

Not worth the risk.

I've had a cheap FP gauge go bad and puke fuel at 60+ PSI all over my engine bay. I got VERY lucky, but it wasn't good.
