Important: Plastic quick connect fittings can be released either by squeezing the plastic retainer release tabs, or by using the appropriate J 37088-A .
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.
