1972 50hp Dual Carb fuel lines, is this right?

[rfields109]

I have not received my OMC service manual yet and thought you guys might be able to help. I am wanting to know how the fuel lines should be connected on this old motor ?

I currently have them connected
Line 1 - Fuel pump outlet in to the upper carb bottom supply connection.
Line 2 - Carb to Carb "small outlet on the side of each carb"
Line 3 - Out the bottom of the lower carb to the intake manifold.
Line 4 - Bottom of the Intake manifold to the pulse in on the back of the fuel pump.

A picture would be worth a 1000 words !
Thank You for the help,

Rusty
Planning to go catch some Crappie! IF the rain ever stops...!

Thanks everybody we finally have the motor running smoothly. The fuel pump was weak, the hose ends were not opening the vent and staying on tightly.
Rebuilt the fuel pump, idled in tank, replaced fueld line ends with GOOD ONES, OMC OEM. Readjusted Idle speed and air adjustments on the water and all is well.

Thank you for the education!
