SOURCE: filling up with fuel, pump shuts of continously...

hi if you look into filler pipe you will see a flap/restrictor just inside this is to prevent wron fuel filler nozzle from entering so unless you put the correct fuel nozzle fully into tank fill pipe and this pushes flap open you will experience slow filling ALSO? to put fuel in tank the air inside must be able to displace emit from tank ok this is done via a hose from tank and is usually clipped along side the filler pipe under wheel arch below filler check and ensure this pipe is clear and also free from kinks? as this if blocked will not allow displacement of air from tank as fuel level increases? hope this is clear enough for you to understand?

There is a balance pump that keeps both tanks within two gallons of each other.

SOURCE: 1988 f250 no power at fuel pump ,no fuel press.

Behind the air cleaner box, there are two relays. Over time they corrode and get stuck...change them out and see if that improves the situation.

The tank is full so why does the gauge indicate it's empty?


1. If it is a new car then Ford have to fix it under new car warranty if there is a fault. It their problem to fix - not yours.

2. If you have the car in your possession you can check if the fuel pump is working. Take the fuel cap off the tank filler tube. Have someone turn the ignition on in the car for 10 seconds and then off again (do not start the engine). Then on again for 10 seconds and off.. If you listen at the open fuel tank filler tube you will hear the pump run for 3 seconds or so and then stop once the ignition is turned on each time. If you hear nothing then the fuel pump is not operating and the fuse and relay for the fuel pump need to be checked. On a new car a problem with the fuel pump is very unlikely.

I have a 2000 gmc 3500hd,the fuel gauge stopped at half way and i run out of fuel. the rear tank is not sending fuel to the front tank?


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.

Just purchased a 97 chev 3500 series pu with dual fuel tanks. Don't know how to switch from front to rear tank. there is no switch


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.

I have a 2000 Chevy 3500 box truck with 2 gas tanks. The gas guage only goes to 1/2 with both tanks full and it won't pump gas from the second tank. How do I fix this.


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.

Fuel leaking out near the filler tube. would this be fuel line coming out the tank? The fuel leaks out only when the ingnition is on and the engine running.


if it is after the car have run or while on park i should say its the line coming from the tank. But since its while the car is running then its the fuel lines that is connected to the fuel pump .It will leak because of while the car is running , the fuel from the tank going to the filler tube . then it will pass to the fuel pump and it will leak while the car is running . therefore you should check on the fuel line that is connected to the fuel pump, which near the filler tube.good day.
