If I'm not building a race car/track car do I really need a swirl pot on my 7 type????

Yes mate, cornering might cause surges. I had a new tank mate with insitu swirlpot. Pretty good.

FI + unbaffled tank or no swirlpot = juddery highspeed cornering. Even MPi tintops of the 90s needed them.

No. All I've got on mine is a small well on the bottom of the tank (about 1/2 pint capacity) where the fuel outlet is. No swirl pot, no tank baffles. I only get starvation if the fuel gets down to 1/2 a gallon. Thats road and track (even full gas through alpine hairpins) and when it does give a slight hick-up I just take it as a warning to top up.

Well to be fair that small well is effectively a swirl pot!

No not for the road i'd say.

If you use a Landy fuel pump, you get the pump, swirl pot and sender unit - all in one package

Same as bmw in tank one.
