ISSUE: This article summarizes the overall service procedure to be used for disconnecting and connecting the fuel line spring lock coupling.
In addition, the service tools and service part O-rings have been recently revised. The service tools (available March, 1987) D87L-9280-A (3/8") and D87L-9280-B (1/2") used to disconnect the spring lock coupling will now fit around the rubber cover on the fuel line allowing an easier disconnect. The O-ring part numbers were changed to specify color. The fuel resistant O-rings 390846-S96 (3/8") and 390847-S96 (1/2") will be BROWN in color while the A/C refrigerant Orings will continue to be BLACK.
