Shutoff valve leaked, and gasket leaked

Difficulty
Easy
Time
30-60 minutes
Tools Used
Socket set
1. Remove hose from shutoff valve
2. Remove remnants of bushing & shutoff valve
3. Push new the bushing into tank
4. Lube inside of bushing with a very small amount of oil.
5. Push shutoff valve into the bushing until it snaps into place. This is easiest to do if tank has been removed, but it is not necessary if you have small enough hands to work under the gas tank.
6. Loosen all vibration mounts.
7. Lift each corner, remove old mount, replace with new mount, go to next corner until all four are replace. I used a piece of wood to hold up the generator between the frame and generator to remove the vibration mount.
8. Retighten each corner mount, operate generator and check for vibration
