Your engine can be adapted to use the old (1983) vintage dual mechanical fuel pumps. You will need to purchase two fuel pumps from Bombardier. Part number 438559 and 393870. Actually both are the same fuel pump, but one of the comes as a "kit" including a special "J" hose that goes between the two pumps. You will have to unscrew one brass plug at the front of the block and install a second fuel hose barb in order to feed the pulse line to the second pump. (the block is already for the new hose barb. ) You will see it when you get ready for the installation.
