lift pump versus intank injection pump
Chaps,
I have a seperate lift pump, swirl pot and injection pump which works fine but is bulky and more bits to go wrong or leak.
How do these in tank fuel pumps work? I mean why don't they gulp air when cornering hard with a low fuel level?
If I made a new tank to suit does anyone have diagrams or could you point me to a site with an idiots guide?
Cheers

Really the tank needs a sump - a small 'pot' which protrudes below the main tank and will hold enough fuel to supply the pump during a
hard corner. The in-tank pump sits in this sump.
There are pumps with a sort of built-in sump, but I'm not sure how those work.

Look for posts on this very subject over on the WSCC.
They've had several threads on the modifications needed and how to achieve it with some helpful photo's too.

Ha! solved it simply. Junked the lift pumps, junked the swirl pot and fed the injection pump directly from the tank.
Difference is I have a tall thin narrow tank which only holds 10l - enough for 6 laps or so
Works perfectly. Anyone want to buy a couple of hardly used Facet Red Tops complete with fittings!!!
