Hi all. I recently rerouted my fuel line and noticed that squeeze/primer bulb has an arrow imprinted on it. Should it point to the motor, or the tank, or does it matter? Thanks.

Re: primer bulb direction

the primer bulb is a (hand) pump.... an arrow on a pump points in the direction that the pump moves the fluid it is pumping..... The reason I said that is so that the next time you come across an arrow on a pump you won't need to ask ;)

awesome. thanks. I'm guessing the pump has a flap, or one way valve, or something in it to keep the fluid moving in the right direction and not back washing? thanks again.

Re: primer bulb direction

two of them.... one on each end of the bulb.... that's how it works.... squeeze and fuel can only flow out one end.... release and fuel can only flow in the other end..... repeat
