I change the fuel pump pressure regulator because it was leaking, but now I only have about 30 pounds of fuel pump pressure on the rail. I don’t know if that is enough or not. I thought it was a lot higher than that.

Good afternoon.

I posted the pressure below for you.

You need a fuel pump. 30 lbs. is way too low for the system.

Fuel Pressure * .................... 338 ± 14 kPa (49 ± 2 psi)

I was wondering, is there different pressure regulators that fit their vehicle? In case the one that I bought is too low pressure or you think it’s just the fuel pump? I replaced the fuel pump like five months ago from rock auto maybe it’s just a defective pump. Thank you the pressure was real helpful.

This is a failed fuel pump. Contact them as this should be covered under warranty.
