Re: Surging helped by pumping primer

Agreed on the fuel connectors…. if they are aftermarket, replace them with dealer supplied OEM. You will be doing yourself a favor! The newer BRP [OMC] connectors have yellow ends on them around the o ring area.
Use of the clear hose to diagnose air in the system, as amuller has described, is a good troubleshooting technique. Or you may just need a fuel pump kit after all those decades of service, probably should be done for reliability anyway.
Are you using one of the new plastic fuel tanks without a vent?
