SOURCE: i have a 94' chevy 3500 dually with the 6.5 turbo diesel.

If it was the trani I would be waiting to hear you say something like it slams into gear or the RPM's go up but the speed doesn't follow. you can try to shift it in low and manually shift it up as needed. It could be that your truck is not starting out in first but rather second. Am I on the right track, is this what your trying to describe.

SOURCE: Serious understeer with 96 Dodge Ram 3500 Dually

Are the tie rod ends tight? Is the trac bar (frame end) tight? The steering boxes on these trucks require more input that a 1/2 ton truck or a car. How is the alignment? The caster on these should be set to about 5 degrees, the original specs allow a lot of wandering.

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.

If this was not a problem before the pump replacement then the sender in the tank may of faied or is contaminated with sulfer which is corrosive to the silver electrical contacts.

Do a search on sulfur corrosion and fuel sender units. Gm has big problem with this. Its possable the stress from removing the old and installing the new pump created an issue with contacts. If this is the case you will now need a sender unit.

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.
