Fuel dumping into valve cover through the evaporation hose

[Lunchmoney]

03 df140 running like crap. Found the evaporation hose coming into the top of the valve cover is dumping fuel into it. Removed the camshaft actuated fuel pump and fuel shoots out of the evap hose every time the pump piston is pressed in. Problem is in the vst correct? Float stuck open or something? Removed valve cover and fuel oil mix poured out!

Yep, that's the problem all right. Float valve in the VST not closing completely.
