There are two types of quick-connects used on fuel pipes. The plastic collar type does not use any special tools for removal. The metal collar type uses J 37088-A Fuel Line Quick-Connect Separator. Refer to Metal Collar Quick Connect Fitting Service to service metal collar-quick connects fittings.
Caution: Relieve the fuel system pressure before servicing fuel system components in order to reduce the risk of fire and personal injury.
After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.Caution: Place a dry chemical (Class B) fire extinguisher nearby before performing any on-vehicle service procedures. Failure to follow these precautions may result in personal injury.
Caution: Wear safety glasses when using compressed air in order to prevent eye injury.
Repeat for the other fitting.
Caution: In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends.
This will ensure proper reconnection and prevent a possible fuel leak. During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.
