Don't buy those hose finishers. They work out almost as expensive as actual fittings and are shit. I did my car in those then had to re do it with proper JIC fittings. Expensive lesson learnt. There is a way you can calculate how bug the swirl pot needs to be. On mine we worked out that a 1l pot would provide 30 seconds of surge protection for 300bhp, which would be plenty in my case so we made the pot as small as possible, 1litre, but you might need a bigger one depending on power.
Goes into an alloy fuel filter in the engine bay.
Nice setup mate and good advice, I know it's tempting to go for the cheaper option but spend money in the right areas and you'll save your welt allot of time and maybe even money. Ask lots of questions mate, I'd say 1.5l+ tank would be idea for any sub 500bhp car.
