My '46 with 350/350 has a Ford gas tank according to the information I am getting. I guess you can tell because the sender mounting is NOT the usual GM or universal 5 hole variety. The sending unit that came with my new gauges DOES have the 5 hole sender.

I did a search, 50 pages! Lots of references to using Blazer tanks for AD and TF trucks, no reference to a specific tank that is optimum for the '41-'46 trucks. Who has done this successfully? What tank did you use?
