'72 Demon, Stock Tank - Elec. Pump & Filter mounting?
That is how I have mine.......Tank , filter , pump at the rear of the tank. -8 to carb with regulator past the end of the carb , and gauge and return plumbed off of the regulator. The return line runs out of the bottom of the regulator , the gauge off of the front port.
Not a great pic , but you can see the regulator hiding behind the accumulator.
