Well said Lynn!

I have a similar system on the DAX
But I run a single LP filter after the Pollack valve / selector and a lot smaller swirl pot (about1.5litres)

Heat build up is a bit of a problem and U have heard from another forum that the small UK style delivery vans (Diesel) use a small radiotor in their return from fuel rail to assist with the cooling

I will see what I can find next time at the breakrs befre buying a new unit for the car

OK I am running a 3.9 Range Rover engine and run a Facit Red top on the Low pressure and a Bosch HP pump for the EFi (Said to be good to fuel for 350 hp) Yes at times the Facit pump hammers on air whenyou brake on a 1/2 tank of fuel but the engine is always fed. The Swirl pot would run the engine for about 3 minutes at idle (We did it in error as I filled one tank with fuel and was drawing from the other (empty one))

Cheers
Ian
