how do you make a swirl pot?

As title. People are asking me to make swirl pots. I have never done it before so I'll be honest.
Whats the internals like?
Is it just an open cylinder inside?
Fuel in, fuel out and breather?
Anyone know?

Found this using google - http://www.fortunecity.com/silverstone/impala/1012/cars/tech/swirl/swirlfaq.html.

Has advise about what goes where and why.
Seems sensible advice, but ymmv.

alloy cylinder,fuel from tank and return to tank at top, fuel to engine at bottom. Breather is a good idea to!

That sort of size! And maybe a baffle just to make sure! The idea is to make sure you dont get fuel starvation on cornering, as long as designed so fuel outlet to engine can neversuck air it will be fine!

would a bleed nipple be more suitable than a breather, or is this what you mean?

just thought, wouldnt need one anyway would it, with the return at the top

just get an piece of RVS tube...

tig weld close the both ends.

(or in ally)

then just connect the entrance (at the top) to the output on the tank...

then hook the top of the pot to the return of the tank, now you have an closed circuit...

now just hookup the pump to the swirlpot.
and if you have return, i would also hook it up to the swirlpot...

Tks

TKS is exactly right, there is no need for breather etc.

Inlet in the side near the top, feed to hp pump from bottom of pot, return from fuel rail and return to main tank teed together in the very top of the pot so it's always brimfull.

Job's a goodun.

I usually use a 6 to 8" length of 3 or 4" exhaust tube with ends welded on, just Migged on, nowt special. If you make the base a square and weld round tube to it you have nice corners to drill to bolt it down with.

Thought a swirl pot was so named as it was designed to swirl the fuel to get rid of air etc? In which case the inlet and outlet pipes should be mounted tangentialy to the main body to promote swirl.

That applies to water i think Mike..but might be just dreaming again

Yes, that would be to get air out of coolant.

We have all assumed that the original question was referring to a fuel swirl pot, which is just an anti-surge tank.

No need to get air out of fuel, you'll not have probs with that.
