Rear Fuel Tank swap

[MACKL]

Pick the one with the largest fill neck size. Otherwise, you spend a lot of time trying to fill up the tank. The 1 1/4 ID necks are too small. Next time I will cut the old one out and weld in a larger size. Kinda hard to weld once you put fuel in it. Even so, I would do the conversion again. I got a tank from Kenny's Truck in Tulsa OK. About $225 for the complete kit. I installed the marker light fuel filler and love it too. Good luck with the conversion.
