fuel pressure gauge reads 0 when car is running
 

car runs fine but today the FP gauge is reading 0. i am running a carter fuel pump and a holley FPR with a jeg's liquid filled gauge.

could it just be the gauge?

What gauge do you have? If the car still runs when it reads 0 then it is the gauge...

Need to know the range of the gauge and where it is connected. If you connected to the return line by mistake, it would read 0 or close to it. Did it work before or is it a new install?

it worked before. its been on the car for a while now.


funny thing is when i started the car today it worked...lol

Silly person, make it unwork. When it not work, there not gas going to car, yet car run fine. You solve rotary mpg-problem ;)

Seriousness On:

Checked the connections for good contact?
