2nd fuel pump
 

Hi all
I have been driving my mates rs wgn on and off and ran out of fuel after 320km
from a full tank.
Got it back to the station and it only took 35 ltr,
Can someone explain to me how the 2nd fuel pump is wired up?
Does it cut in and out as the other side of the tank gets lower on fuel?
Does it have its own relay?
Thanx
Chris

Maybe your fuel gauge isn't accurate and it wasn't that low on fuel. There is only one pump

RS Liberty Wagon tank is 60 litres.

The seccond pump is a jet pump i think. so it uses the return fuel to pump the fuel over to the other side. Check for blockages in your return line and in tank
