You will have issues pumping diesel from pumps designated for truckers. While you can fit the nozzle into the tank opening, the flow out of the nozzle is too high for the hose diameter and tank to handle; especially because there are some bends in the house and it is not a straight shot into the tank.
It will start foaming and backflowing to the point it kicks off the pump continually. You have to barely press the trigger so it will flow continually and then it takes forever to fill. The front tank is a little better than the rear but it is tough filling up at truck stops if the flow out of the pump is very high.
I thought there may have been a kink in the hoses to the tanks. I had Thor check it out but everything was ok.
