Fuel Preasure Highs!

[Dale G]

My 87 Gn has 52psi with or without vacum. I bought a adj fuel regulater and the preasure stays the same, it has a stock pump. If I drive the car hard the gauge will read 59psi at idle, with or without vacum, any ideas are welcome since I am going to Toronto dragway park this Friday?.

Are you checking the fp with the line off the fp regulator?

if your gauge is accurate, your return line is plugged or the regulator is bad

ps....do not go to the track until this is fixed

Fuel Preasure Highs

When I'm checking the preasure the vacum is off the regulater, and when I put it back on the preasure still stays the same. The factory regulater was doing the same thing, So I know it's not the new adj regulater from Kirbin. The fuel gauge is brand new 3 days ago. I will try and look for a kink in the return line on Thursday (free time ?). Are there any areas I should look at first for the return line?. Thanks for your input.

I think the first thing to do is detach it somewhere close to the regulator and see if your pressure acts normal....obviously you need to deal with the fuel and attendant fire possibilities

good luck
