Hi All

The fuel pump on my OS 91 is not drawing fuel and a replacement is over £50 !!!!!!!!!!!   i cant find any leaks from the presure hose from the crankcase to pump so must assume a fault with the diaphram in the pump. Has anyone tried repairing the pump ? or can i just bypass it straight to the carb, fit a pressure nipple to the silencer and pressurise the tank ?

all suggestions welcomed

Hi Richard . As far as i am aware you can bypass the pump and fit a pressure nipple ;at least that was possible on the ealier pump. If the motor draws fuel as normal by priming and continues to draw whilst runn then it will be ok.

Regards

E.D

cheers Philip

i will give it a try before i shell out on a pump. Didn't buy engine for the pump, only bought because the price was no dearer than a non pumped model.
