What are the fuel line fitting sizes on a diaphragm LP?


Thanks

Diaphragm or recommended piston-lift-pump :


TOP = OUTLET = 14MM x 1.5 ( a common tapered 1/4-NPT WILL easily screw into these threads and I managed to accomplish this leak-free after several attempts before I knew better, it's best that you get the proper metric fitting )


BOTTOM = INLET = 1/4-NPT ( it works fine, but I sort of suspect that this fitting might just possibly also be 14mm x 1.5 metric; most everyone has used the NPT fitting here )




Seeing as there are about a bejillion different part-numbers and applications for the CARTER piston-lift-pump, and many of these applications have nothing to do with a Cummins, I would assume that the inlet/outlet fittings on many of these are liable to be just about any size/thread imaginable.
