This fuel pump looks very simple to the point that it is confusing to me.

Does anyone have one of these on their bikes to compare to?
I would like to know if this is electrically driven, vacuum driven and where would you put it on your bike?

I know some riders have chosen to by pass the pump because they are faulty in some cases. My bike is gravity fed and I would like to revert or add the pump.

 

keep it gravity fed if its been converted to it. That standard pump is electrical and nothing like that pic you posted.

the pump is the archaic mitsubi pump and they are very unreliable, still used in variations on the older VF bikes (which I change to gravity feed) and still used on KTM's which get converted to othe rpumps.

 

That doesn't look like a pump at all. It looks like a vacuum activated fuel on/off device.

You don't need a pump. Fuel injected engines need pumps to keep pressure up but carb engines don't. When the fuel supply is above the carb float level you can depend on gravity. In my 56 years on this earth, gravity has been there every day I have gotten out of bed.

 

I guess bike bandit sucks then for miss-labeling this part.

 

The info may be correct but they may have dropped the ball on the photo.

 

From Motorcycle Superstore's website's description- "Mikuni Pulse Fuel Pumps employ an engine’s fluctuation in crankcase pressure to pump fuel from a remote fuel tank to an engine’s carburetor".

 

Newton was the man ! Edison was good too just not as reliable just kidding Bill
