Riding Mower Vacuum fuel pump Dissection!

[@twocvbloke]

Usual thing that goes wrong with these is damage from ethanol-laced fuel drying out rubber parts, and also depends on whether the manufacturers actually use materials that are safe for use with ethanol, and if it's an old, pre-ethanol days pump, it'd crap out anyway, I prefer my ethanol in my whisky...

LOL, yes the ethanol sure hasn't helped many people but the corn farmers, the whole thing is a waste, we need the land to grow people food, but pocket lining seems to be the flavor of the day these days :(

Much like the one on my friend's Craftsman. Fortunately the pump was okay, it was the fuel line that was bad! Previous owner had used non-fuel-rated hose and it had swelled up so bad inside it was plugged! Ran great once that was fixed. Ah, Mikuni, like the carburetors!

Yes, sometimes fuel does strange things to stuff. My one supercharged 2 stroke wouldn't make a second run, as the electrical tape spacer I made had slipped once the gas vapor got to it.
