I had asked a question earlier last week about model 100 pump HP ratings and someone asked me to post the model information from the pump tags, so here goes. My pump options are as follows: 1) 9554-25, p/n 691-127-C91, s/n 7M51352, 1000/2500rpm 2) 6A-100A-9281-A10, p/n 681-257-C92, s/n 7R4165, 700/2500 3) 631-559-C91, s/n 422523, 700/2400rpm 4) 6A-100A-9236-B3, p/n 681-257-C92, s/n 7L46572, 700/2500 5) 6A100A9274-11R, p/n 687-034-C91, s/n 7C20709, 700/2400 6) 6A-100A-9348-C1, p/n 681-242-C91, s/n 7M2287, 2600
Those are the pumps that I have to choose from. I"ll be using one of these to replace the multi-fuel pump on a military 478 Hercules to install in my tractor. I"ve been told the model 100 pumps are a good changeout for the multi fuel pumps to make it work for a farm application, but I don"t know anything about the model 100 pumps. I"d like to be as close to 175 engine HP as possible on a stock pump setup. Any feedback on which of these pumps would work best for me would be appreciated. Thanks.

Today's Featured Article - The Fordson F Ignition System - by Anthony West. A fellow restorer contacted me earlier this year asking for some help and advice on a model F that he was restoring. He had over a period of months spent a fair amount of his hard earned cash on replacement parts for the old "trembler" ignition. Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!! If i said that this was a little frustrating for him that would be "conservative" in fact the problem had reduce
