Fuel level phenomena

[petlee10@me.com]

Guys,

What I am going to relate I have experienced in my 335i, GTR and even my Cayman S.

Why is it when my petrol tank is full (above half tank) the acc pedal feels livelier than when the petrol tank is low ?

Isnt the fuel pump suppose to regulate the pressure of the fuel going into the cylinder head ?

I've experienced this too!

Car feels way better with a full tank...

Why I feel less fuel faster ?:confused:

fuel tank's pressure shouldn't causing any fuel delivery pressure up or down ... and our R35's pumpS is damn powerful already la~

answer will be...: Is that because more fuel more weight then feel more stable?:D

This has been reported in NAGTROC forum. Essentially it is pressure built up from fuel vapor. You can hear pressure is released every time you open the filler cap.

em...pressure makes fuel easier to pump.
