Fuel Pressure Gage Installation and Removal
Tools Required
• J 29658-D Fuel Pressure Gage
• J 29658-500 Fuel Pressure Gage Adapter
Installation Procedure
Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
