Fuel Pressure Release: Service and Repair
WARNING
To reduce the risk of fire and personal injury, it is necessary to relieve fuel system pressure before servicing fuel system components.
A small amount of fuel may be released when servicing fuel lines or connections. In order to reduce the chance of personal injury, cover fuel
line 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 complete.
PROCEDURE
-
Disconnect negative battery terminal to avoid possible fuel discharge if an accidental attempt is made to start the engine.
-
Loosen fuel filler cap to relieve tank vapor pressure. (Do not tighten until service has been completed.)
-
The TBI model 220 contains a constant bleed feature in the pressure regulator that relieves pressure. Therefore, no further action is required.
