In Italy we say Nourice....or Anourisse.... or Neurice.....or else Anourice.....

It's a cockpit draft, and with this, there're not any problem of draught.....

Probably in England you call it FUEL SWIRL?!?

However....if i want to fit the fuel pump Bosch 044 out of tank.....how can i do it?! Have you some photos or other material?!?
