Default Re: Kiki Inline Injection Pump

Your description of the work you did on the Kiki pump is really great and many thanks. I have an Onan MDJE with the same Kiki pump and it works fine but has a leak where one or both of the injection valve bodies thread into the pump housing. I have not found any diagram of the pump so I don't know if there is any kind of seal in this location. In the picture you posted I don't see any seal. If there is no seal and I've checked that the valves are really torqued into the housing but it still leaks, do you think I just have to replace the whole pump?

Sorry for the late reply but your post is the best info I've been able to find.

between the delivery valve holder and fuel pump body;Oring (small section) is sealing the fuel. remove fuel injector pipes and unscrew each holder (dont loose the spring and delivery valve in the bottom of boat).
