2014 Montauk 190 Merc 150 Sputtering Out No Fuel at Filter
On a recent fishing trip aboard my 2014 Montauk 190 the 150 Merc began to sputter. The fuel tank is 3/4 full. It worsened as the trip went on and I turned back. Eventually the engine stalled and wouldn't restart. I checked the fuel filter and she was bone dry?? I removed the fuel demand valve and there was fuel at the base of the valve housing/pickup tube. The valve is mounted atop the inboard tank.
I sucked some fuel through the hose where it attaches to the fuel filter. Don't laugh but, it I took a little more effort than I expected. The outboard ran but sputtered and stalled. I also depressed the slot on the fuel demand valve, but no fuel flowing to the filter. I am expecting the fuel pump to draw the fuel into the filter when you turn on the key.
I don't know if its a venting problem, clogged pick up tube or the fuel demand valve. I'm going to try with the valve first as its the easiest to change. Any suggestions would be appreciated.
