What can fail
The fuel hose running from the fuel filter to the throttle body can rub against the fuel pump plate underneath, causing it to leak. Leaking fuel near a spark or flame could ignite and cause a fire.
What the fix does
The fuel hose will be replaced with a curved molded hose, and a new bracket and grommet will be installed to keep it away from the pump plate. The return hose will also be replaced.
