All my fuel related stuff is here
There's a drawing in there that shows the layout I used but the wiring is different to what I did in the end. I still haven't got round to fitting an inertia switch either. I stuck my swirl pot as high as possible with a large bore feed down to the injection pump to try an guarantee it never ran dry
The swirl pot needs to go up in the engine bay as close to the feed to the fuel rail as possible really to act as a header for your main injection pump (assuming you haven't got a sump fitted in the main tank in which case you don't need it at all).
is the 5 series Sportster tank baffled?
