Hey fellas! I'm needing an Autometer Sport-Comp fuel pressure gauge to match my existing pair of gauges. The two offered are 0-15psi and 0-100psi. From what I can tell, 15psi is too low of a max pressure to use on my truck, and the 100psi gauge may be difficult to read the small fluctuations in pressure. Share your thoughts! Also, I need advice on the Vulcan, isolator, mechanical gauge combo vs. going with Vulcan and electric gauge combo. Thanks!

 

you need a 0-30 psi guage. 0-100 psi is no good. 0-15 psi isnt enough.

Electric guages suck, unless something has changed in the last few years and isolators are problematic, again unless something has changed in the last few years.

Isspro EV series (fully mechanical) is youre best bet.

 

Thanks! I prefer mechanical gauges anyway. Is it unsafe to install a fuel pressure gauge inside the cab without the isolator? I read that somewhere.

 

I love my isspro ev2 electronic fuel pressure gauge 3 years now no issues. but I used my own version of a snubber so only enough fuel to work the sender is used so no bad fluctuations hit the sending unit. bought another one for the fummins project.
