Going to be plumbing my fuel tank next week and am wondering if i should add a swirl pot?. I'm not likely to be doing any track days and if i do only 1 or 2 a year at most. I'll be running a 2.0 zetec on R6 throttle bodies and MS. I have currently got 8mm fuel line and return ran through the tunnel ready and some braided fuel line coming next week.

adding a swirl pot will obviously cost more in fittings a 2nd pump and the pot itself. Is it worth the extra money. This is meant to be a Low cost build afterall.

cheers

I would add a 1" deep cup sized sump into the bottom of the tank then arrange the pickup so it draws from within this which will provide a 1/8 pint comfort zone in your situation.

My low pressure pump failed on an event so I bypassed it, my tank is set like this and it caused no issues so have not bothered to restore it.

I can't find the pic of mine, but that's what I did.
A small pot on the bottom of the tank, about 1" deep, 3 or 4" diameter, but crucially, only fed by a 1" hole, so fuel goes in easy by gravity, but can't slosh back out under cornering

If you are using the standard flat bottom tank and intend on doing fast road and track I would say a swirl pot is very much needed with fuel injection. If you have a sumped tank then you won't.

Sump & baffles or swirl pot
My standard box tank with no sump or baffles needs a swirl pot for quick roundabouts, use to cut out or splutter just after the roundabout
