Ok folks, here’s my situation.
I ‘look after’ a bike for a mate who lives in Egypt. It hasn’t been run for a while and a while ago I noticed fuel dripping from under the tank - familiar story I know. On investigation, I noticed that there was a bad leak from the seal between the fuel pump and the tank and a slight weep from the black fuel line that goes from the underside of the pump to the elbow connector on the engine.
I removed the fuel pump and whilst removing it, a wire has broken right at the point where it meets the base of the pump – not a great place to try to solder. As now the fuel pipe and the wiring needs replacing, I decided to source a good used full fuel pump assembly including a fuel line from America. It will be here early next week.
So, my question is;
When I go to fit the new pump, how best can I seal the pump to the tank? I have sanded the surface of the tank and was planning to use an aerobic sealant to complement a new O-ring which I have ordered from Aprilia in the UK. Is it simply a case of clean the faces of the pump plate and the bottom of the tank, apply the sealant and then bolt in the pump to the tank? I’m aware of the issue with the u-shaped hose inside the fuel pump which connects the two overflow-type nipples and I plan to JB Weld these for belts and braces protection.
Any help appreciated….
