Fuel Pressure Release: Service and Repair
WARNING: To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system
components.
After relieving system pressure, 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 completed.
When servicing the fuel system use the following precautions:
a.
Put a "CAUTION FLAMMABLE" sign in the workshop.

Be sure shop is supplied with an adequate fire extinguisher.

d.
Use a suitable container to catch any fuel that may leak from system during service.
