What type of material do you use to insulate elecrical connections that you make inside of the gas tank.I am currently replacing the high presure pumps in 93 F250 with after market pumps and after inspecting the lenght of wires on the new pumps it would appear that new wire connections will be made that will be inside of the tank.Any input that you have would be greatly appreciated. Thankyou

 

dont need to insulate as gas is nonconductive. put shrink wrap aroun connections but test for gas resistive first.
