Here's a math-based answer. > Estimate the horsepower of the engine, here what a 1961 318 had per the 1961 318 specs (230 HP I think) > Figure the brake-specific fuel consumption. (BSFC) = (..."an engine typically requires .5 pounds of fuel per horsepower every hour at wide open throttle.") Take these numbers and multiply them together and divide the product by six. 1961 Poly 318 = 230 HP (230HP x .5 lbs) / 6 lbs = 19.1 GPH So a fuel pump that produces at least 20 GPH of fuel. Feel free to double check my math. :) Here is a reference. https://help.summitracing.com/app/answers/detail/a_id/5245/~/what-size-fuel-pump-do-i-need%3F Thanks, Gary H. > -------Original Message------- > > > I have a friend who wants to go to an electric fuel pump for a 61 318 > Poly.
