Tractor's 12-Volt Electrical System Used To Operate Diesel Fuel Pump

Tractor's 12-Volt Electrical System Used To Operate Diesel Fuel Pump TRACTORS Modifications 24-3-40 Leon Dick, Mt. Hope, Kan.: "I keep my diesel fuel tank on a trailer. I didn't want to have to connect cables from the fuel pump on the trailer up to my tractor battery all the time so I installed electrical boxes on each side of the tractor, and wired them up to the tractor's 12-volt system. I also attached a 110-volt, 3-prong male plug to the cord on the 12-volt fuel pump on the trailer. It lets me use the tractor's 12-volt system to operate the pump and eliminates the need to use jumper cables off the battery. "You can buy these box receptacles at almost any hardware or electrical supply store. I used existing holes in the tractor frame and ran a bolt through the back of the box. I also grounded the receptacle by running another bolt through the tractor frame and attaching a ground wire to it. I installed a box on each side of the tractor so that I can drive the tractor up to either side of the trailer. I made this conversion on my Deere 4430 and 4420 tractors and also installed a box on my Deere 7700 combine for the same purpose. "I paid about $1.25 for the box, 50 cents for the receptacle, and $2.50 for the cover."
