Has anyone ever rebuilt the original Bosch fuel pump successfully after it failed?
I am using an identical looking pump at the moment which I bought new. Unfortunately, the pressure is not up to spec and while the bike goes OK, the tickover and low speed running is not great.
I stripped and cleaned out the original pump but am having difficulty putting it back together so that it will spin freely.
All the components are clean and corrosion free and the rotor and rollers all spin nicely until I try to tighten the outer plate which keeps them all together. Any more than fingertight and the rotor won't turn.
Has anyone any experience on this? Does it need petrol to lube the rotor?
I hate throwing the pump away if it can be resurrected and would put it back in the bike and keep the other as a back up.
