I am replacing my mid 80's 150 HP powerhead with a used 200 HP unit (S/N 0B129605) and have a question regarding the fuel pump (which didn't come with the new 200 powerhead). The 150 used a Design II pump and has two pulse ports cast into the block that match the fuel pump. The 200 has the mounting pattern for the Design II pump, however only has one pulse port cast into the block and what appears to be a hose to another port. The parts diagrams don't describe this configuration and I have assumed that I need to find the special 90 degree pulse line fitting to connect the hose to the other port on the back of the fuel pump?? So many different fuel pump variations.....
