I recently purchased a KEC440-23LC motor for a gokart project i am working on. the only problem is that i can not find any information on how to run the fuel lines. if any one can help it would be greatly appreciated.

68nova200,
The fuel pump mounts to the underside of the dual intake manifold. The bottom port of the fuel pump is for the impluse line from the crankcase. The other 3 ports located around the middle of the fuel pump will have an arrow indicating the flow. 1 of the ports is the fuel inlet from the tank, the other 2 go to the carbs. The lines from the pump to the carbs run up between the carbs and arch over top of each carb to the fuel inlet port.

I suggest putting clamps on the fuel lines before you put them back on. I was having problems with them blowing off at high RPM's last year. It was a lot easier putting them on again after I had to rebuild the fuel pump. I also found that if you have the impulse line to long it you can't get the pump mounted again. The other lines might be breather lines, are they smaller than the fuel lines?

They are overflow / vent lines.

ok so they dont connect to anything. now does this take premixed gas or is it automatic?

The overflow/vent lines do not connect to anything at the bottom, they are just held in place by small brackets. The fuel premix @ 50:1 ratio. Do you know the year of the engine, the 76 model requires high octane of 91.
