    Fleetwin – I confirmed today the pump I installed is not working.    The air pulse line to the pump is tight and not leaking or restricted and is providing adequate pressure and vacuum but the pump is only pumping out a few drops.    All other fuel inlet and inlet lines are confirmed as tight and not sucking air or restricted.    So I am going to remove this bad pump, install a bypass cover with the fuel port, install the correct pump and block off the outlet nipple on the manifold.  I’m sure this will cure the problem.
