Fuel Tank Thickness and Pump Compatability?
fuel tank and pump ?
I am about to start building my fuel tank and have a couple of small questions
1) can i use the bike's pump / filter assembly on the bottom of the tank?
2) does the bikes pump/ filter assembly include its own swirl pot?
3) minimum thickness of tank wall in ally? and steel?

my tank is 1.6mm alloy which i thought was as thin as you would want to go, its not the sides that will fail its the joints where the weld sits that
will crack and leak.
If its an in tank fuel pump (injection normaly) then they have baffle plates but you still want to help it by welding it in a pot which is then welded
to the bottom of the tank, this means you have to turn the car over to stop fuel getting to the pickup.
Sorry about my spelling, im an engineer and only work in numbers.

Using a Bike Fuel Pump
I think it is a very good idea to use a Bike Fuel Pump. I have a Hayabusa powered BEC and have fitted a Suzuki GSX R1000K7 fuel pump. this has several
advantages. The main one being that the Suzuki fuel pump regulates the pressure at the pump so only needing one fuel pipe to the engine. It comes with
a fuel sender which with minimal modification works well to indicate fuel level. The under bonnet area is clear of any unneccessary fuel lines or
pressure regulator. So I would strongly recommend using one. There is no swirl pot on the Suzuki pump but is was easy to make a circular area to mount
the pump in and act as a swirl pot.

I have the bike pump mounted in the bottom of my tank on my R1 install, martin Keenan put a boss on the bottom of the tank for me to bolt the pump to.
I have no sump and have had no problems of fuel starvation to date. Car hasn't seen much continuous track action yet though, only used on road
and hillclimbs.
