I read the post about the 1968 mustang sending unit and i tried it wonderful!. There are two things one is longer 3/8 fuel hose and running the ground wire to the tank thats it so simple a caveman can do it lol. I checked the range of the float and is the same in everyway to the Mav. like i said the only differance is the nipple is facing 40% left and its only 1 wire instead of 2.
