I have a 1959 IH Farmall 560D tractor. Im guessing its the D282 engine. Serial number on tractor is 21089. Im not sure if its the early or late model 560D. It is nut pumping fuel and i have the chance to purchase a new old stock injector pump at a good price. Heres the question..... The beginning of the model or part number on the existing pump is "DGBFC". The model or part number on the new one is "DGFCL". They both "LOOK" very very similar. Same locations for all the lines and cables and mounting and overall appearance is almost exact. Will the new one "DGFCL" work for me as a direct replacement? Where can i find compatibility information or another that will work if the one mentioned wont? Thank you.
