I finally found a good tank in Mexico for $30. No one seems to have the sending units. I can get a new one for $80!!!! More than twice what I paid for the tank??!!! Anyway, if anyone has converted their in-cab to something else and wants to sell the sending unit, let me know. Of course, if it's not in a reasonable driving distance, I'll pay shipping. I hope to get one for less than what I paid for the tank or so. Or if anyone wants a custom made tank for your bed, I have the one that is in the truck. I'll do an even swap. I think it holds about 20 gals. I don't remember the capacity for sure. The tank seems to be well made except for the cap. It just sits on the inlet. So if it's full and I make a right turn, gas spills all over. If someone had a welder, they could weld on something to accept the cap. I also wanted the in-cab because of having limited bed space in the short step-side bed.
