Don S,Hot Rod and 46gmcpu. Thanks guys for the replies. The tank is stock late model Chevy Tahoe/Suburban 31 gals The filler neck is a straight shot to the tank with no bends or elbows. I will try the hose trick. If that does not work I will drop the tank and look for the vent tube. If I put a hose on the vent on top of the tank what does the other end of the hose hook to? Or is it just left open and loose?
