Fuel tank capacity

[deadscoob]

Hi All,

I know each tank is approx 40 litres, but does anyone know the minimum needed to actually provide fuel - are the pickups right at the very bottom so if there are a couple of litres it'll get to the engine, or does it need X more?

Cheers

If using the factory fuel system then I think you will need about 5 litres in each tank to get reliable fuel flow.
The flat bottoms do not help utilise the full capacity. A small sump would have helped.

Realistically, you have about 65 litres of useable capacity.

That looks like a very neat solution. Who's going to try it out first?

Have in my tanks now, no sense of fuel starvation on hard turns or accel on the track. I like it.

Nice to know, but did you modify the pick up tube to get to the bottom of the tank?

I put a line from the -6 fitting directly to the Holly mat. no other modifications needed. The mat can even be sideways in the tank, fuel only half way up the Holley mat and it still picks up fuel and no air. Nice stuff.
