Truck newbie here. Need help w/EFI tanks

['63GENIII]

Yes, welcome to the forum. I ran an 89 Blazer tank in my '63. Its a 31 gallon and it does hang pretty low especially for a 2wd. Im not sure if there was a smaller capacity Blazer tank that would not hang as low but Im sure that someone here would know this. The 89 tank sending unit is interchangeable with the 97 and I think that they both had different pressure pumps. You may be able to find a stock pump that will suit your LT1 that would also drop into your tank easily. Mine is a side fill although I have not cut in the fuel filler. Its given me a little anxiety thinking about cutting another hole in otherwise cherry fender.
