We have a little Spra-Coupe sprayer in the shop, it has a Poo-Joe (sp) engine. They use a belt driven CAV / Delphi DPC series injection pump. #8444B340A
The parts we need for rebuilding the pump are not available.
I have tried my best since early August to find a good core pump, in hopes of taking 2 and making 1 working pump.
So far have came up with nothing, surely there is one setting somewhere with a broken timing belt (destroyed engine) that still has a viable injection pump.
Any leads would be GREATLY appreciated.
