Every morning after sitting overnight my 01 tdi beetle is hard to start. It cranks over fine. It may take 2 or 3 trys to start. The car starts fine after the engine has been run. I think I have a fuel bleed back problem to the tank, causing air in the lines after sitting overnight. Is there a check valve somewhere in the fuel system which may cause this problem...thanks!

Try inspecting the fuel tank level sensor for leaks. I think there's a check valve there but not sure. If there's no problem there the fuel leak is at the fuel filter, injection pump, or fuel return lines.
I have a fuel level sender and recirculation valve on order. The injector pump is new and I had this problem before replacing the injector pump. I'll try the fuel level sender, fuel filter with new recirculation valve and O-rings....will post update later. Thanks
Change the fuel filter and O-rings. See my post here: http://www.myturbodiesel.com/forum/f5/hard-starting-means-bad-turbo-6985/
Hope that helps!

Thanks for your response. Have a new filter and went to the straight through style (older models w/o tee - no o rings). Still see problem after. Could it be a faulty/plugged pickup in the sending unit? Maybe b/c plugged pulling severe vacuum and drawing in air at connections?
