what are yall running for a rail pressure gauge

[MACKIN]

Yup that be the one sep it's 2 1/16 mounted in the over head in a billet Trippen mount.

Call Fleece Performance for the explainations of electrical in cab and not fuel line under hi pressure that you don't want to blow a line connection better to see what they know would happen if done wrong.

Gotta be electric won't pass teck with a mechanical gauge in cab if youre gonna race it.and agree not doing mechanical gauge for fuel

I Just got an Elec/ dig oil pressure gauge. got an adapter and just installed im the check valve.

Idk. The rail pressure gauge is electrical but I guess the fuel pressure is mechanical and has fuel running to it. It's getting mounted in the cab regardless tho.

I would not under any circumstance mount a mechanical fuel pressure inside the cab of my truck. Diesel has a way of finding the smallest leaks, and it smells really really good as it soaks into your carpeting and insulation matting. LOL! I would use an electrical gauge, little more expensive, but its safer wont smell up the truck, and easier to route wires than copper tubing.

I already ordered a mechanical fuel pressure gauge and a electric rail pressure. I'm not to worried about 10 psi of pressurized fuel in my cab. If 50 psi doesn't leak out of my boost gauge then I'm not worried about 10. I'm gonna tap the fuel pressure gauge into the top of my filter head

I would use an isolator on the fuel pressure gauge.

X2. You can buy that to use on your mech. Gauge.

What is it and what does it do lol link?

Here is my autometer isolator.

 

[madmatt]

for the price for an isolator and a mechanical gauge though you coulda bought a good electrical gauge

 

[Dirtymaxx03]

How is using an isolater any better than just running it off the filter head?

the iso keeps fluid from leaking in your cab should there be a leak

 

[Dirtymaxx03]

how in the hell does it do that? if i run into a leak issue i may get one.

[Dirtymaxx03]

i see. so it somehow converts the pressure from the fuel into air pressure going into the gauge. or something haha

 

[madmatt]

yep

 

[madmatt]

that AM iso alone is gonna cost ya over $100 itself tho.

 

[Dirtymaxx03]

thats an expensive little bastard. im gonna pass on that and if i get raw diesel thrown into my face i'll fork out the $$ for one

 

[madmatt]

or just start with an electrical gauge :thumb:
