[alfa] GTV6 fuel pump/filter orientation

[Shures <shures@xxxxxxxxxxxx>]

The system pressure is close to 40 PSI and should not surge due to the 
by-pass nature of the pressure regulator.  The pump supplies fuel to the 
fuel rail and injectors at a pressure and volume sufficient to allow the 
pressure regulator to constantly by-pass fuel back to the tank.  Choking 
the hose AFTER the regulator cause the pressure to rise significantly 
(I've seen 65# in an instant).  I doubt surging will occur unless there 
is a low fuel condition but suspect others will reveal the real reason 
for the U shaped hoses.  Could it be to get the electrical contacts to 
the rear of the car and away from the normal direction of travel?
