I've got a problem with a 94.5 PSD I got recently. I'm not sure if it ran out of fuel or if the pump has quit. BIL thought it was starving for fuel after we pulled it for about 4 miles trying to get it started and it would only sputter and idle rough for a short period before dying. Replaced filter and there was only 1/2"-3/4" of fuel in the bowl. Been awhile since I changed filters on a PSD and I can't remember, but shouldn't the bowl be nearly full after removing the filter? Any ideas? TIA!!!!!
