| - | - The oil tank mounting bracket has a large grommet in it. | ||
| - | * The hole was enlarged to help cut down kinks while passing 3 lines through it. | ||
| - | * The hole was filed out to a rounded rectangular shape and a large round grommet was cut down fit the new hole. | ||
| - | - Because of tight space, short sections of copper tubing were used in place of thick rubber hose. | ||
| - | * A short piece of rubber was placed at each end of the copper lines. | ||
