Fuel Pump Relay
WARNING:
-
To reduce the risk of tire and personal injury, it is necessary to relieve fuel system pressure before disconnecting fuel pipe fittings.
-
After relieving system pressure, a small amount of fuel may be released when disconnecting fuel pipe fittings. In order to reduce the
chance of personal injury, cover fuel pipe fittings with a shop towel before disconnecting, to catch any fuel that may leak out. Place the
towel in an approved container when disconnect is completed.
FUEL SYSTEM PRESSURE RELIEF PROCEDURE
1. Loosen fuel filler cap to relieve tank pressure (do not tighten at this time).
2. Remove fuel pump fuse.
3. Start engine and run until fuel supply remaining in fuel pipes is consumed. Engage starter for 3 seconds to assure relief of any remaining pressure.
