Gas spitting out when filling
So after getting my gas tank changed over with a stock tank and new neck, if I try to fill it with gas full speed at the pump it stops and spits gas back out the spout. Do I just need to adjust the two openings above the spout?

If the tank can't vent very well fuel will come back up the fill spout.

I'm thinking the holes need to be larger you may have to pull the tank and install a barb an vent hose from the top of the tank to the top of the fill inlet

I thought there is just a vent valve in conjunction with the ccp. So when the ccp solenoid opens it draws air through the vent valve and vapor out of the ccp canister into a ported passing in the tb ?
