Put some dish soap on the rubber, push into the tank hole, slip 1x2 into the handle of the tank and over the new part and pry down pushing it into the hole. Took about 2 minutes.
old valve easily pulled out with screwdriver and pliers
install difficult due to 40 degree cold temp and bushing didn't want to squeeze into fuel tank hole
install required lots of liquid soap on bushing, which popped into place by using upward prying pressure from 3"X24" plywood braced into under-shelf of gas tank
used same technique to insert valve upward into bushing
