New replacement fuel boot only for shut-off solenoid above. This is the exact replacement part made by the OEM. It keeps the solenoid plunger and spring clean to prevent binding. It also holds the plunger in the solenoid. About a 5 min job to remove and replace. I know this is a lot of money for a piece of rubber but it is a patented design, hard to get and it's less expensive than a new solenoid.
