I used oil to help get some Push-Loc fittings on the fuel lines. Wanting to flush the lines with gas before connecting to the carbs, I powered up the pump and I just get a dribble out of the hose. Sorry, didn't measure volumes. Even backing the adjustment screw all the way out doesn't make much difference.
Disconnected the regulator and the pump shoots a high volume of gas (looks easily over 100 gallons/hour).

How much gas should get to the carbs?

Thanks
Roy
