Fuel system Tfsi questions

[AudiCoupe]

Hi,
I've got a webasto that is not meant for a tfsi engine and is supposed to be connected to the return line on older cars apperently not on the tfsi because the return line from the FPR (fuelfilter) gets preassurized.

My question:
Does the tank on the tfsi get pressurized or could I just hook up a fuel pump to the tank to supply my webasto with fuel?

Okey, I got the anwser on a swedish forum... the tank get pressurized...

New question:
Anybody know where I could get a pressure reduction valve for gasoline?
I need to hook it up to the fuel return line and reduce the pressure to max 10psi...

Please if anyone know who makes such a valve please tell me because I can not find one!
