My injector pump has been leaking from the throttle shaft, stop shaft, housing for shafts gasket and now a new leak from pump body to the head where injector pipes are fitted. It is not useable anymore as it spills more fuel than it sends to injectors, so i ordered a reconditioned one.
The new pump was reconditioned some time ago by a man who has passed away and stored in sealed plastic for some years.
The pump looks good but where the anti stall screw should be is a bolt and rubber o ring instead. I am now thinking the bolt was put there to stop air getting in and i need to remove it from old pump and put it on the new pump. Should i be doing this or is it normal to have it blanked off?
