Is there a way to rebuild the fuel pump on a vs800? the pump seems to click when I hit the start button. I have taken the outlet off and hit the start button but no fuel pumps out .

Probably the easiest fix is to get a new one. You can use a generic low pressure pump - search on eBay for cbr600 fuel pump. They're under $20.

Yes it can be tinkered with. Its a simple linear armature with make and break contacts. You can clean and bend them to make it work.

There are small pumps off cars that will work -I paid 15 dollars for mine. I walked in to a car spare parts shop and put it on the table. I ignored an comments like what is this off,( or in Thai --rot alai) she walked away with it and came back with a small pump off a Suzuki Caribbean ---an old 4 wheel drive car that is known to turn over a lot. Looks like a tiny little Range Rover.

took the old fuel pump apart cleaned it and still does not work I ordered a used oem one from ebay.

This is the one you want:

I wouldn't be too keen on buying a second hand one.

They are bit tricky but its not rocket science. I took the armature return spring out of mine and fitted another type on the top of the armature that I can adjust. This means the fuel pump pressure can be adjusted as it directly relative to the armature return spring.

well the used oem part came in had to solder one wire and shrink tube it plugged it in and it worked.
