could be fuel elated, there are two fuel pumps, the high pressure pump to feed the injector system and the lift pump to get fuel from tank to the high pressure pump. Check fuel filter also and start there. The fuel pumps are expensive. What have you checked so far and eliminated?

David Johnson is wrong about that. The Chevy HD dual tank has two sending units, one in each tank , one fuel pump, a fuel pump relay switch and a equalizing pump. If the truck stalls out at 1/2 tank, it is the equalizing pump. That pump, pumps fuel from the rear tank to the front. If the pump is out, the front tank empties, the truck shuts down, the guage reads half tank because the back tank is still full, but the equalizing pump won't pump the rear fuel tank load to the front. Hence the problem you listed above, not a sending unit.

There is no switch. What you have is a "transfer pump" that moves fuel from the rear tank to the front tank as required, so that you get a smooth declining indication of fuel left on the gauge in the dash.

If the transfer pump goes bad, any fuel in the rear tank will not be pumped to the front tank so you'll only be running on the front tank.

The fuel level indicator is on the front tank, so the gauge will still accurately register the amount of fuel in the front tank.

their is a transfer pump inside the rear tank that transfers the fuel to the side tank this is possibly the cause of your issues..

cartrigde type is locted at the top of the crossmember just forward of the gas tank on driver side of the vehicle,,,,,,,,non cartradge type located on front of the fuel tank..

Fuel levels are equaled in the tanks via a frame mounted transfer pump that transfers fuel from the rear tank to the front tank where the main pump is. Your transfer pump needs replaced, and should run about 60 bucks. Should find the pump mounted to the frame between tanks.

Hi I have a 4x4 2003 chevy 3500 silverado dually with dual tanks
rear tank stoped pumping into front tank and was full . I siphoned the fuel out of rear tank and fuel gauge reads 9/16 full . is there a way to reset the fuel sending units so they can calculate the fuel readings. I always filled the two tanks with the same amount of fuel
until now ? I'm thinking there is a inkine fuel pump

pump is your only choice at this point...HOWEVER, it does have sufficient fuel in the tank and switched to the supply tank (in case you have dual tanks) right?

The fuel pump is in the tank, there is one for each tank if you have dual tanks, also change the fuel filter with pump.
