My 92 SSE seems to run short on fuel under accelaration. It runs fine at low RPM but runs out of power when you put more demands on the fuel flow. I first noticed it after running some isopropyl alchohol fuel treatment through the system. I replaced the main fuel filter on the frame rail and I am considering changing the fuel pressure regulator on the fuel rail. Is there anything else I should look at before I bite the bullet and replace the pump in the tank?

It also has the common problem with the fuel gauge sender that causes the gauge to ground out and go to "E" when the tank is completely full. After driving about 50 miles the gauge will work normally.

My original pump started losing power in upper RPMs, when it got warm. It was fine when it was cold. I tried cleaning injectors, new pressure regulator, and new filter before I finally did the pump.

That'* not an uncommon problem on the H-body. My 99 has been doing it for well over a year now. It'* the fuel level sensor. It'* integrated into the pump. So, if you change the pump to fix your other issue, it'll solve the guage issue too.

The fuel level sensor IS NOT part of the pump. The pump mounts to the sensor/sender assembly. You may need a new pump AND sender.

Problem solved.

It was the fuel pump in the tank. Also had a problem with the fuel gauge so the sender had be replaced and the plastic baffle in the tank was broken as well.

Pump $140.00
Sender 130.00
Tank 100.00
Labor 140.00

$500 dollars later, it runs great.
