Mercury Verados 300 2nd generation lift pump woes ?
Can anyone tell me if Mercury has redesigned the FSM on 2nd generation Verados ?
We keep getting, I think air in the canisters in rough water conditions .. tanks are clean, filters are new and fuel system ( lines ) are tight to the engines .. I am starting to think the plastic quick disconnects are the culprit ... thanks in advance

Can't say I've seen that problem. What I have seen is the float switch in the FSM get ,hung/stuck/go bad or otherwise not send the signal to turn on the lift pump. You need to get CDS hooked up and make sure it's working right
Also they did update the program from the early motors to look for less fuel mass used before the pump comes on. An ECM flash to a updated version should keep more fuel in the module.

Has anyone redesigned a better fuel delivery system than the OEM FSM ?
I don't like the idea of this system ... would rather the old Bosch type external fuel pump and an internal hull low pressure delivery pump system ?
