So I am in the process of bringing my motor (340) up from a deep sleep after body restoration. I never had a fuel pressure gauge and decided to add one. I noticed at the start up cold the fuel pressure was initially 6 psi. After some minor changes in timing and idle and warm up it dropped to ~2.5 psi. From then on it stayed at ~2.5 psi regardless of idle/rpm.
It seemed to be running fine no stalling or anything. I’ll check the float heights when the motor cools down a bit….
I don’t know what caused the drop from about 5/6 psi down to 2.5?
Normal?
Oh and yes I am running a good pre-filter…
