  3. Step 3: Disconnect and remove fuel tank
    • Spray the bolts on the straps holding the fuel tank with penetrating oil.
    • Loosen up the clamp at the top of the fuel neck.
    • Grab onto that hose and twist it free and pull it off.
    • Unplug the connectors by pulling out the safety tabs.
    • Unclip the green clip behind the fuel tank by prying the tab and pinching to disconnect the line.
    • Make sure you have a catch pan ready because this will leak fuel.

    • New large black lead connects to the old black lead.
    • New thin black lead connects to old black and white lead.
    • Purple and purple leads connect as do the grey ones.
