TOOLS REQUIRED- J 34730-1A Fuel Pressure Gage
- J 34730-262Fuel Pressure Gage Fitting
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.
