2003 TC35 Fuel issues

[wgreennewholland]

Hey all, new to the forum and tractor ownership. I have a 2003 New Holland TC35 and the fuel bowl keeps getting pulled down after the tractor runs for about 40 to 50 min and will suck itself dry and run the fuel bowl out of fuel and shut off. Even if the tank is topped off. Flushed the tank, replaced the fuel hoses, replaced fuel filter housing, replaced the lift pump, cleared out the return hose with air, replaced the fuel cap, replaced the 3/16 fuel hose connections and clamps between injector 3, fuel filter housing and the tank return hose. Any Ideas as to why air is getting in the fuel filter housing? tHANKS ALL

Sounds like you've done a lot of trouble shooting so far.
I can only add that I've read of clogged shut-off valves at the separator. Apparently some valves have a screen in them that can get clogged up.
Is it possible there is still junk in the tank that is continuing to cause flow issues?

Is the tank vent open?
