Fuel Tank: Testing and Inspection

Fuel Tank:

1. To leak test the Fuel Tank, make sure that the fuel filler cap is tight. Disconnect the Fuel Tank vent line from the tee near the bypass valve (left side of engine compartment above charcoal canister). Lightly and slowly presserize the disconnected vent line with a hand pump to about:

0.63 psi (1.3 in. Hg)

2. After five (5) minutes, the Fuel Tank and its related components and hoses should still hold about:

0.50 psi (1.0 in. Hg)

3. If not, check for leaks at the fuel filler cap and in the vent system between the charcoal canister and the Fuel Tank.
