Replacement Fuel Tanks

I have a tanks inc tank. It is nice. I got the EFI setup, the only issue is the sending unit holes don’t match well with the tank. Will need to break out the Dremel to do some grinding to make it work.
Wow, I didn't have that issue but like anything made there are tolerances and if the sending unit is off one way and the tank is off the other way I can see that happening.
