    Default Fuel leak in lifter valley

    Where is the likely cause of a fuel leak in lifter valley and fuel filter area? Do i need to remove the manifold to fix it? Its a minor leak only when truck is running. 1996 F code 2500 Suburban

    Un bolt the fuel filter from the manifold, there may be enough slack in the 3 hoses that connect to it to inspect their connections, and the fitting for the water sensor, the o-ring can leak. First make sure there is no leak from the filter retaining ring on the top, it is difficult to make it seal.
