2.5 pump in a 4.0 fuel sending unit

[Strokermjcomanche]

My 87 2.5 Comanche that I just purchased needs a fuel pump .The PO told me that the tank and sender  had rust inside and he purchased a new tank along with the used MJ sender .Looking at the current pump I ran the Bosch pump  part number and it was for a 4.0, so I'm guessing the sender is also from a 4.0  . I went and bought several 2.5 pumps and they are all too small for the 4.0 sender , the only pump I have yet to try is the Carter # p74032 ( no one has one locally). So has anyone made the two work together ? Or do I just look for a 2.5 sender (if that's the problem)?

Others have used a 4.0 pump to run a 2.5...........so I have read.

 

It's a volume issue, not a pressure issue. 

 

The regulator is in the TBI, 14psi, and it should handle the additional volume, apparently it does.
