They will be 1/8" or less in thickness. As for fuel flow, you will want
as big a fuel feed to the surge tank as you can get, using a Hi Volume,
low pressure feed pump. No need for floats or valves either - just make
sure you vent the top of the tank back to the main tank so the surge
tank is always right full - vapour pressure does not cause the level to
drop. The little (smaller than regular BarBQ tank) refillable bottles
would likely be best to use. Actually, if you use an external (frame
mounted) EFI pump, you don't even have to drill any holes or modify the
tank at all. Just unscrew the valve assy, and modify a pipe plug to
accept the required lines. Feed line goes either top or bottom, outlet
to the bottom, and small vapour bleed at the top.
If you decide to use an intank pump, buy a brand new, unpurged
tank.(they are cheap enough) and you can cut, drill, and weld with
impunity (after removing the valve, of course).
