What does the fuel pressure reading on our cars if you measure it at the fuel line in the engine bay.

i'm getting a fuel pressure guage and i have to choose what PSI to go up to.

15?
30?
60?
100?

thanks

 

it's is like 55 psi I think. I haven't been able to drive my car for over a month due to the weather, so it's a little fuzzy. but it's either 45 or 55 psi. But if you are going FI anytime soon, go with the 100.

 

According to the Service manual, idle pressure is 51psi.

 

Personally, I would not bother with a fuel pressure gauge on a stock fuel system. Once you turn the key, it is going to stay right around 51/52 PSI regardless of how you drive the car. If you are going to use the Vortech SC, I would definitley recommend it.

 

i'm wanting the guage because i will be using nitrous and just wanted to keep an eye on it. thanx

 

Moved.

 

can anyone recommend a decent fuel pressure gauge, i am currently running a vortech sc, with the fmu and aux fuel pump that is supplied with the sc. i would like to keep an eye on my fuel pressure. looking for something to match my defi boost gauge that matches the stock gauge cluster. anyone use the defi fuel pressure gauge ?
