Are you sure the gas tank is above the level of the carbs? The fuel is in a dummy tank under the seat, and that is about the same height or maybe lower than the carbs, hence you need a fuel pump.. Even if the dummy tank is above the carbs it can't be by much so the pressure is going to be very low (Meaning the flow will be low) so I suspect the fuel pump is needed to keep up with the fuel requirements of the engine.. I have not tried running without the pump, but I am sure Honda would have removed it if they could to save a few Yen!! So I suspect it is required.

And when it's empty? Unless you can keep it full all the time :) I guess you need the pump.

gto. If you look at the posts on this site you will see how someone else has been able to use a fuel pump for a car. This is a lot cheaper then a honda fuel pump and is supposed to work as good. Hal New Albany In.

You need a new pump!!!!! Will not operate efficiently without a pump.

Even at a foot above the carbs,fuel pressure needed to fill the carbs is still 2-3 psi.At best with a full tank,fuel weight and height will only create about .4 psi .The fuel pump(unless it's fuel injected)is a pulse type and only runs with engine rotation.Just turning the key on will not operate the pump.

You can use a fuel pump for a Honda Preilude. It's pressure runds 2-3 psi. The pump price is around $60. The inlet and outlet are both on the same end.
