Fuel Systems

When servicing the fuel system observe the following cautions:

^ When removing or installing the fuel gauge sending unit or fuel delivery unit from a full or partially filled tank:

- Provide exhaust extraction close to the mounting hole for the fuel delivery unit in the fuel tank to draw off escaping fumes before starting work. If no extraction system is available, use a fan (but DO NOT place fan in path of fumes).
- Wear disposable protective gloves whenever handling fuel.

^ Place a "CAUTION: FLAMMABLE" sign in the workshop.
^ Furnish the shop with the proper fire extinguisher.
^ Disconnect the battery ground cable before any service work is done.
^ Place a suitable container under the connection to be opened.
^ Slowly open fuel connections, allow pressure to escape, and catch spilled fuel in container.

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

^ Disconnect line or hose, then plug all fittings.
^ Put any drained fuel in an explosive-proof container and put the lid on securely.
