In an ideal world one of these would be fitted, but are they absolutely neccessary for an injection 7 car if the tank is baffled, can't see where one would go if one was to be fitted.

you could have a small pot welded on the underside of the tank, effectively all you are trying to do is stop the injection pump run dry as they use the fuel to help lubricate them so it can lead to failure and obviously lack of fuel to the injector rail.

If well enough baffled or as said with a small cylinder by the pickup onthe underside of the tank you can do without, optherwise you run a lower pressure pump from the tank to an external swirl pot, then the swirl pot feeds a head of fuel to the high pressure injectino pump.

I think the Landrover fuel pump assembly has a built in swirl pot as well as a sender unit. It is about the size of an Aero filler cap. Quite a good little unit.

See the parallel thread on this subject within the last week recommendation was to use a golf pump with built in swirl pot

Don't think it is completely necessary, but don't make the same mistake I did. I mounted my fuel tank and fuel pump at roughly the same level, and fuel injection pumps really need fed fuel, the don't really suck fuel so you need a head of pressure behind them. I would think if you raise you tank a few inches and make sure your pump is below the level of the tank you should be ok, of course after saying that, if you plan to use it on track day, you would probably be better installing a swirl pot.
