I've been looking at the Dallara tank I have in the garage and it appears to only have a single HP fuel pump within.

What prevents fuel-starvation? Does the tank contract around the pump as the fuel is used up?

Cheers!

Years ago my bladder had built in baffles, now I would use the small squares of fireproof foam you stuff down the filler tube.

From past experience the bladder tank is built with three components.

There is an ali tank with a bolt on lid, this hold a special re-enforced rubber bladder.

The bladder is placed in the tank and the bladder filled with a plastic foam like a scrubby, the lid is then bolted on the top to hold it all together.

The resulting tank can now take a major hit without leaking.

I rolled my Datsun race car at 120 mph, the car landed on the tank, car was almost destroyed, not a drop of gas came out of the tank.
