lpop??????? help

is my lpop bad? my in dash gauge last night was reading low and the more gas i gave it the lower it went. pulled over checked my oil and it was fine. fired right back up and i babied it home. it stayed lower but noticed no differance in performance or any lag or noise. u think it could be my lpop or faulty gauge?

Are you having a hard time starting? When you go to start it, how quickly does the oil pressure go up on the truck? (Cold Start.)

I'd remove the sender from the top of the HPOP resi and install a mechanical gauge before doing anything else. IIRC the sender is 1/8" NPT so even a cheap 0-150 psi air compressor gauge will work for testing purposes.
