Rebuildable LA Fuel Pump

I have used Then and Now for kits to rebuild Carter fuel pumps.

Older Mopars (like my 56 Plymouth) came with rebuildable Carter fuel pumps with the screw together cases. Later on, these got replaced by cheap, non-rebuildable pumps except for 426 hemis and the like. For a 340, you got a non-rebuildable cheap pump stock, for more, you had to look in the aftermarket to get Carter high performance replacement pumps. These all (?) have 3/8" inlet and outlets, while the earlier factory poly V8 pumps had 5/16. HP pumps might also have had heavier duty internal springs, but other than the inlet/outlet sizes, the early non-hipo Carter pumps pretty much looked just like the aftermarket hipo Carter pumps.
