  6. Inspect for fuel leakage.
    • After assemble the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.
    • Repeat this operation two or thee times, then check for fuel leakage at any point in the fuel line.
