I believe we had a little misquoted or miscalculated number for the required flow for the injection pump on a 4020. What I see on the NE test about the max fuel use in ..gallons per hour.. (GPH) is 6 plus something lets just call it 7 per hour. A pint of flow per minute at 8 pints to a gallon calculates to 7.5 gallons per hour. You do need to add in some extra flow for pump and injector return but I believe that is only a small percentage of the GPH used by the engine. One gallon per minute is 60 GPH, the 3 gallons per minute suggested is 180 GPH, I am not even sure if black smoke rolling tractor pullers use that much. In my opinion if he can produce a pint a minute or to be safe a pint and a half a minute he should have plenty of fuel flow. Carbureted cars used to have a required pumping spec out of the fuel pump by cranking the engine with the starter a certain length of time. I do not know if a 4020 repair manual contains such a spec.

No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
