Yamaha Keihin fuel pump Diagram ? - Snowmobile Forum: Your #1 Snowmobile Forum

Does ANYONE have a diagram on how this thing goes back together ?

I bought a rebuild kit and have had the thing apart 3 times- I'm getting a 5 psi +/- pluse to the vacuum line but it doesn't suck gas- It runs till the carb get empty.

It's a 1980 SS 440 with the Keihin Triangle shaped pump with 1 fuel in 1 fuel out and the pulse line.

Thanks I hope.

don't they have arows on them telling you what way the fuel goes? infront of where the hoses hook up? every fuel pump ive looked at has arows and putting them bac on was an idiot proof job... yours could be different though...

Yes they have arrows to show me where the fuel lines go.
That part is correct, but i had it APART! the diaphragm and gaskets and all out on the bench, there is 2 gold springs inside this pump(juss to let any1 no).
I need to know were the gaskets and diaphragms should be placed, or else it wont pump.
That little peice you see ther was in about 8-10 peices on my bench. need to no correct way it goes together.
