Bis Fuel Pump problems!

[f40fanatic]

Hello! Had rolling problems with my pump for a while. It conks out but then i blow through the pipes and breathers and it runs again. But today it finally gave up the ghost... Took the fuel pump off and the rod that runs it does NOT move when i turned the engine over :/ it vibrates slightly but not a visible up and down movements... HELP WANTED PLEASE!!!

the tension on rod to hold it to the operating cam on crankshaft is from the fuel pump itself.  I dont think it will actually stroke up n down very much in normal use. So either crank cam lobe is now worn beyond reasonable limit (unlikely) or more usually the rod has worn so that in length it does not actually operate pump enough. Pull out rod and measure it against a new one, which are easy to find and cheap enough
