Fuel Hose Connections

[drb1313313]

I have a 1976, 70HP The fuel pump hoses were rotted off after years of sitting around. There are three ports on the pump, to where do these nports connect too? The front one is too supply line, the middle and back ones I dont know, Does anyone Know which goes to what?

Re: Fuel Hose Connections

The three lines are 1) fuel inlet -- comes from the fuel tank. 2) Fuel outlet -- goes to the carb inlet. 3) pulse line -- comes from the pulse port on the engine. That line has the pressure/vacuum pulses that works the pump diaphram.
