Fuel pump pressure at snap throttle

Hello,

With the engine idling the fuel pressure should be at 51 PSI.
So being at 35 PSI, it is lower than it should be.

What kind of issues are you facing?

I have attached the fuel pressure test procedure below for your reference.

Let me know of any questions.

Thank you.

I was just concerned because the fuel trims seemed like they were starting to get high. The only issue that i may have (or may just be normal since i live in phoenix) is it sometimes seems to ping when accelerating and it's got, but it has done that for years.

Engine pinging/knock can happen for early combustion due to carbon buildup inside the combustion chamber. It can also happen if the engine gets too hot. Other reason would be using of poor quality fuel.
