My '65 Morgan with a 2.2 l. full race TR-4 with Weber carbs uses about 10
gallons per hour when racing at Thunderhill using a 3.7:1 rear axle ratio.
Your Stromberg carbs are designed to operate at a fuel pressure of about 1.5
to 2.5 lbs. per sq. in. I would recommend that you use facet electronic
pump (they make one that is rated at 1.5 to 3.# pressure) or use a pressure
regulator if you use a pump of higher rated output.
