does anyone have a correct diagram or pics of fuel line routing from where the line enter the outside of the motor to its complete layout under the motor cover ? its a 1977 1150 mercury tower of power inline 6 cyl. when i bought the boat the fuel line had no ball primer and was cut or rotted off where it comes out of the boats stern.

Re: fuel line routing for 1150 mercury

On that motor, there is a quick disconnect on the starboard side of the motor. The fuel line connects there. The primer bulb is between the motor and the fuel tank or water seperator.

Under the cowling, the fuel line runs a couple of inches from the quick connect to the black plastic cap of the fuel pump. Then the fuel line runs from the back elbow nipple on the fuel pump to the top carb cover tee, mid carb cover tee and the bottom carb cover el.

Some serial groups have twin fuel pumps on the transfer ports. Let me know if you have those and I can explain that routing.
