Recently, I have been having an intermittent fuel problem where under idle or very low rpm, the engine would stall, and the fuel bulb would be soft. The engine also seemed to run rough at low rpm's

On Saturday, I rebuilt the fuel pump and the engine is definately running much better but I now have an intermittent problem where sometimes at idle, the engine would stall but now, the fuel bulb is collapsed (stronger fuel pump).

This problem seems to only manifest itself on the main tank, the portable works fine.

I have taken appart the vent line to make sure the fittings and hose are ok and they are. My next step is to replace the fuel supply line, connectors, and bulb.

Any other thoughts???

It sounds like the anti syphen valve at the tank outlet is sticking
