Gas pouring out gas tank vent hose

8 posts in this topic

Why do I have gas pouring out of vent hose coming from gas tank cap?

Just up and started after riding for several hours. I took apart the gas cap and see nothing wrong.

thanks

Try to avoid filling the tank up to the top. Leave a little bit of space for air and expansion and you'll avoid most of that.

I can't really understand the description but i think what's happening is the gas is sloshing around and just a little is getting out the vent hose.

What he said. If your tank was only half full then :applause:

The tank is only half full when it is occuring, and it only happens when I really start moving. it is literally pouring out. That morning I filled the tank up to the top, it did nt happen until a few hours later after the tank drained to half full. That is why its a little confusing to me.

I will try a new one-way valve, it must have up and broke. and yes its pointing the right direction

thanks,

Mike

First I would try a new hose, and maybe new cap all together. I can't think of anything else causing such pressure build up.
