Anyone seen a fuel pressure gauge with a max of about 20 psi? I want to install one on my tbi moter.
only FP gauges I have seen ate 15psi max and 100psi max... I am trying VERY HARD to find a mechanical gauge that has like a 20psi or 30psi max as my TBI motor is at about 18psi unter full load...
I am currently using a AutoMeter 15psi gauge and the FP gets PEGGED at WOT...
Here's what I have:
30 psi max.
I've noticed that it reads incorrectly when it gets heated up. Apparently this is just the way it is for the fluid filled gauges since the fluid expands and fights against the fuel pressure resulting in a low reading. It reads right when cool though.
The slick setup is to run tubing into the cab, maybe that's what you had in mind anyway.
Can this be used with an (Autometer?) isolator (for incab installation)? Do you know what diameter the gauge is? 2 1/8"?

A fuel line in the Cab?? /forums/images/graemlins/yikes.gif No thanks! Burning to death aint my idea of a good time.
Do it right! Use an isolator. /forums/images/graemlins/thumb.gif
No, they have isolator tubes with some other kind of fluid in them to transmit the pressure into the cab.
Oh sorry man.... I just didn't want someone to get the idea they could run a fuel line in the cab.
