im lookingto buy a swirl pot for when i do my 20ltr convertion to stop fuel starvation. i have been looking around at different ones and have become slightly cofused!! why do all the ones i have looked at have 3 - 5 inlets/outlets?
in my mind there should just be one inlet and one outlet.
can anyone shed some light on this?

you need at least one outlet and one inlet and then a breather outlet. Without a breather outlet a swirl pot is useless

just buy an injection tank.. its already got one in it
depending on what you are using the car for, i woudl of thought for normal use the standard in tank one will suffice, if not you'll need something like

because it only works to a point!
it all depends on the spec and intended use of the car!
you can't get gsi/gte tanks new anymore iirc?
You wont need one on a road car.
The injection tank doesnt have a 'Swirl pot' as such, it just has a dish shaped baffle aroung the pickup, but even that is not enough for high G sustained cornering that you will encounter on a track if running a high pressure fuel system.
You want a swirl pot with a minimum of 3 outlets. one for the feed FROM the tank via a low pressure facet pump, one from the feed to a secondary high pressure pump which feeds the rail, and another for the return. (on a 3 inlet, the return line is 't'd off, one to the swirl pot, and one back to the tank). On a 4 outlet pot, one connects to the pressure regulator return, and the other connects to the tank return.
A swirl pot does NOT have a breather, if it had one it would properly pong of fuel constantly and be a serious fire risk!
