Fuel Pressure Regulator

Removal Procedure

CAUTION: To reduce the risk of fire and personal
injury, it is necessary to relieve the fuel system
pressure before servicing the fuel system
components.

CAUTION: After relieving the fuel system pressure,
a small amount of fuel may be released when
servicing fuel lines or connections. Reduce the
chance of personal injury by covering the fuel line
fitting with a shop towel before disconnecting the
fittings. The towel will absorb any fuel that may leak
out. When the disconnect is completed, place the
towel in an approved container.

NOTE: Compressed air must never used to test or clean
a fuel pressure regulator, as damage to the fuel pressure
regulator may occur.
