My 67 coupe has the foot pump in it with the harness plugged in & two hoses going thru the fire wall. I mounted a tank where the bag is supposed to be. Now assume I need a pump. I can't find any loose wires coming from the fire wall that would possibly power a pump motor. I can't find any info as to how it originally was put together. I've got the larger hose from the foot thing thru the firewall going to the tank. The smaller one I have no idea where it would go. Nor do I know where the small hose from the nozzles go. So far I haven't found a decent drawing or diagram of this system. So any input would be appreciated ......what pump motor, wire to power a pump motor etc etc Thanks !!!!!
