So I got my hands on a fuel pressure gauge and hooked it up to the line. Just ran the test and I’m sitting between 3.5 and 4.3 psi, which is right in spec. After letter the truck sit for 15 min, I fired it back up and it was reading at 1.5 psi. Could it just be vapor locking? I’d be surprised if that was it after such a short period running. I’m thinking that installing an electric fuel pump would remedy that. Any thoughts?
