Thanks for the advice so far. My donor tank was rotten, but had 2 (I think) little pipes fitted to the left side. 1 for the feed, and 1 for the return. I was hoping to fit a similar system, but to an external swirl pot. My main problem is how to connect these 2 pipes, and what to use. I presume I need to things in this order:- Fuel tank, filter, swirl pot, fuel pump, then feed to front of car. Any more help would be gratefully received.
