Dry rotted rubber

  • James from PICAYUNE, MS
  • Very Easy
  • Less than 15 mins
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 dripped gas when opened on cold sub zero day
4 of 7 people found this instruction helpful.
  • Alan from RADFORD, VA
  • A Bit Difficult
  • 1- 2 hours
  • Pliers, Screw drivers
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
