Fuel Pump: Service Precautions


WARNING: Adhere to the following procedures any time the fuel system is being worked on in order to reduce the risk of fire and personal injury:

- Keep a dry chemical (Class B) fire extinguisher near the work area.
- Place a "CAUTION FLAMMABLE" sign in the work area.
- Work in a well-ventilated area. Do not smoke, and keep sparks and open flames away.
- Wear eye protection.
- Use caution when working near the catalytic converter to prevent the possibility of burns or fire. (The temperatures within the converter can exceed 537 degrees C (1000 degrees F).)
- Relieve the fuel system pressure prior to disconnecting fuel system components.
- Disconnect the negative battery cable except for tests where battery voltage is required.
- Use a suitable container to store or catch fuel.
- Do not replace fuel pipe with fuel hose.
- Plug all disconnected fuel line fittings and hoses.
- After making any fuel system repairs ALWAYS inspect for fuel leaks.
- Replace all pipes with the same pipe and fittings that were removed.
Do not reuse "O" rings. Always replace.
- Do not attempt repairs on the fuel system until you have read the instructions and checked the pictures relating to that repair.
- Adhere to all Notices and Cautions.

NOTE: If available, use system bleed valve (schrader) to relieve pressure.

NYLON FUEL PIPE CAUTIONS: In order to reduce the risk of fire and personal injury observe the following items:
- Replace all nylon fuel pipes that are nicked, scratched or damaged during installation, do not attempt to repair the sections of the nylon fuel pipes
- Do not hammer directly on the fuel harness body clips when installing new fuel pipes. Damage to the nylon pipes may result in a fuel leak.
- Always cover nylon vapor pipes with a wet towel before using a torch near them. Also, never expose the vehicle to temperatures higher than 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any extended period.
- Apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings. 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.)
