What is normal Fuel Pump Pressure

Topic starter

Hey Scotty!  Love your videos and enjoy learning ways to maintain my vehicles!  I have a 2013 Silverado with the 5.3 V8 and was wanting know what type of fuel pressure I should be getting at the rail. When I test, I get 60 psi with the key turned on, but not started.  After I start the engine, my pressure drops to 44. Both readings are stable.  Is this acceptable, or is my fuel pump getting weak?  Thank you for your help.

I don't think so. Do you have any performance issues?
