Okay, I sent an email to Mike McCluskey and he replied straight back with the following:

Paul;
All the Comp.s and SC's had the 42gal. alloy gas tanks from AC Cars. It was a baffled sump with two pick-up tubes. A main and reserve. The electric pumps were only hooked up to the reserve pick-up tube and then ran up the chassis along with the main fuel supply hose to the engine mechanical pump which all the engines had. It tee'd into the output port on the Carter or AC engine fuel pump. It was primarily a system to get back to the pits when you started to run dry on the main circuit, not to boost performance or flow.

Does anyone know if there is a "reserve" pickup on the standard Kirkham fuel tank?
