Taping into fuel?
 

Ok, so i found a mechanical gauge on Geno's that comes with an isolator (SSPRO R5607R Fuel Pressure Gauge (0-60 PSI)-Geno's Garage)

Question, should I run a T fitting on the supply line (between the lift pump and vp44) or run a banjo bolt on the test port (return line?) with a snubber? Im assuming the isolator with help with pulses regardless of where i'm taping the fuel from?

no the isolator will NOT help with pulses. you need a needle valve or snubber regardless.

the isolator is just an overpriced piece of garbage that will go bad in a few years and make you freak out thinking your lift pump is going out because the isolator will start to leak on the anti-freeze side.

run a tapped banjo bolt to the output side of the fuel filter. That's where I ran mine until I got a 150GPH fuel system that completely bypasses the stock fuel filter. now I run it straight to the fuel systems gauge port on the output side of the filter base.

I guess I forgot to mention I have a FASS 150 HD lift pump. Its pushing out too much psi and thats why im getting a mechanical fuel gauge to figure out where im at

in that case run a t inline or run from the test port. make sure you use a needle valve or snubber though.

if using a needle valve just barely open it a crack... that will stop the pulses.

Awesome. Thats exactly what I bought from Vulcan Performance. Any tips or write ups for hooking up a pressure gauge? Running SS line into the cab and not using an isolator.

SS line?

I would just use napa airbrake line...

Its a stainless steel braided line kit from Vulcan Performance. Same as a grease gun line but comes with npt adapters

you don't need all of that... save your money and keep it simple :tu:

literally all you need shown there...

but you would use the T fitting instead of the tapped banjo bolt..

Already bought it all... is that the air brake line? Where else can I find that, I dont have a Napa. Does advance auto carry it?

yes, that is the airbrake line.. rated forover 150psi so the sub 30 psi we run is never getting though that line :tu:

$16 for 100ft of it there :doh:

little excess when you only need 6' of it..

might check local auto parts stores around you. usually something they have behind the counter...
