New fuel level sender only reads 3/8 when full - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72 C/20 pickup: 2 months ago I swapped out the old sending unit for a new one. Worked perfectly. I just swapped out the old tank for a new LMC Truck replacement tank. Put the two month old, known good sending unit in the new tank and it appears the float is hanging up on the side of the new tank. That is my assumption anyway. It read anything below 3/8 of a tank properly, but the highest level is 3/8. Any options for addressing this without pulling the SOB out for the third friggin' time?
