Fuel tank foam, good or bad?

[hollowpockets]

Hi knowledgable people out there.

Would like some info to act on really, I know a few of you have swirl pots/double pumps or fancy in tank baffles but not got the funds to go down that route and the car would nevr get finished.

So had a look at tank foam, anyone know pro's/cons of this stuff? Bear in mind that I'll only do a few track days a year and will eventually do a swirl pot set up. It's more for short term.

How much is needed to be effective in a noble tank?

Does it need to be one large block or can several smaller 'cubes' be stuffed down the filler neck?

Does it sink to the base or float around up top if the blocks are too small?

If it was to sit in front of the tank outlet would it restrict flow to any real effect?

Thanks!

Ah right i see. Is the sensor in the tank a lever type? I guess it would affect that too.

I noticed pro alloy do a race tank with collector and outlet on the other side which looks good but no price on they're page, anyone know how much? would that save having another pump and swirl pot?

Cheers

The Pro-alloy tank is mine & to my design, it has a proper fuel collector inside with a dip tube sensor & is foam filled via the cover plate at the top, fuel exits on the left hand side as viewed from the rear & the finished tank is insulated.

Cheers Kev, tank sounds good, what sort of money are they asking for one including foam and sensor?
