A stock fuel pump should not be that noisey , a commmon upgrade is a walbro 190 or 255 . from gen 2 eagle talon. these are noisey to very noisey
you have to drop the fuel tank, remove the hoses after it is lowered a bit. once completely removed open up the sending unit and pull out the fuel pump , replace and re-assemble
most fuel pumps on most cars are located inside the gas/fuel tank, unless there is an alternative fuel pump added post factory.

The proper fuel pump pressure for a 1989 Isuzu Trooper typically ranges between 30 to 40 psi (pounds per square inch). It's essential to check this pressure when diagnosing fuel system issues or performing maintenance to ensure optimal engine performance. Always refer to the vehicle's service manual for specific details and recommendations.
