I am installing a Sniper EFI in a 66 Plymouth Satellite. I wanted to avoid drilling in the tank for the return line. Am I able to use a fuel sending unit from an A body 63-76 or from a 68-70 B body? They both have the return line in the sending unit. I know that the 66 B body tank is deeper at 9-3/8" compared to 8". The The A body tank is 10-3/4" deep. If I can use some sort of aftermarket generic fuel sending unit for this application then let me know that as well. If I end up drilling in the tank it is not the end of the world, but I wanted to check. The other option might be to buy a 66 b body tank with the return line, but my tank does not need to be replaced and I am not finding that those are made either. I have also read I can drill in the filler neck or vent line, but that it can add air to the fuel that is not needed. Thanks in advance.

 

For Me... I would just drill the tank and put a bulkhead fitting in and be done with it.... But you mite check with Aeromotive industries and what they have to offer if you haven't already?

 

Welcome. There are a number of manufacturers that make drop in EFI fuel pumps and tanks designed to do this job, that’s how we’re doing our ‘70 B Body.

 

Does anyone know if a 66-67 coronet (B-body) has the same fuel tank as a 68-70 charger? The B body platform is such a wide range, but I'm finding two styles of tanks and I'm doing an in-tank sniper kit (I've done 14 of these kits). Not familiar with mopar cars and its parts.
