Anti-syphon valve ?????

[macojoe]

The anti-syphon valve is in the top of the tank fitting that the hose connects to.

The pick up hose comes out the tank then you have a square like fitting that the hose to the motor goes to. In that square fitting is the ball.

I removed mine long ago!! Might be all gunked up?? But I bet you go back to the fuel pump when you are done.

Things to ck

Vents need to be clear!! or they will stop the flow!!

sock on the pick up in the tank, get cloged and no gas

the anti-syphon valve

filter?? This new gas is cloging all the filters!!

the primer ball its self

the filter on the motor??

little O rings on the gas line connector

and last the fuel pump.


The quickest way to find out if it is fuel pump is to run a 6 gal tank with a different hose.

If it runs good then look at all the stuff above, if still no run then look at the fuel pump!!
