My D3B--27Y03729 starves for fuel after about 1/2 hour run time, it starts at 30 psi fuel pressure and then slowly dies down to 0 and then starts missing--lower the throttle and it goes up to 10 psi. shut it of,wait 15 minutes and start it and 30 psi.
I have installed new fuel filters, cleaned the screen in the fitting at the transfer pump, blown the line out from the transfer pump to the fuel tank and fuel flow under gravity is fine, I have hooked up a fuel pump to a hose and sucked about 5 gallons out of the tank bottom and it was all clean.I also removed the fill cap to see if venting is a problem.
the parts diagram for the fuel tank shows two valves at the bottom of the tank. one a drain and the other needle valve for fuel supply. I also observed a second line going to the tank bottom with no valve. The parts diagram also shows a screen in the tank, with a part number, and after some research it screens fuel for the drain valve,of which i don't understand--
appreciate any opinions on this
