2003kawasaki eliminator fuel line hook up. - KX 125 kawasaki Motorcycles

You need a hand held engine scanner to see what the sensors are telling the engine computer. This is how mechanics today diagnose engine troubles. One thing you could check is if the fuel pump is putting out the correct fuel pressure at the injectors.

the line with the filter on the end goes to the pipe at the pump inlet and the other goes to the out let line back to the tank
the primers sucks fuel from the tank through the pump into the float diaphragm and back to the tank the action is to fill the pump and main jet system with fuel and to eliminate any air in the carby

there should be a main fuel line which is the largest size and a vacume line which is smaller in diameter cheers

go to sears and purchase the fuel filter and fuel line kit for the chainsaw. in that kit will have a hook that you fish through the outside of the tank to the inside, you attach the new fuel line after attaching the fuel line to the fuel filter, to the hook, then pull it through the hole. disconnect the hook from the fuel line, cut the small piece off where the hook made the hole and attach to the carburetor. finish by pushing in the fuel filter inside the fuel tank. the kit will also have more detailed instructions and possibly with illustrations. if sears doesnt have the kit, check with a lawnmower repair shop.

Hi owjbhend...
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line...lubricate the fuel line with some vaseoline very lightly...about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.

Hi

Some bikes have a vacuum petcock. Whenever the bike started up the petcock opened itself up and whenever it shut down, the petcock shut down too. Check to see if the petcock is set to on. Check to see if the fuel line is hooked up. Check to see if you have a vacuum line, and if it's hooked up. Check to see if the gas tank were possible vacuum locking due to a clogged vent. Alternately haul off the carbs and clean them out. Check to see if the fuel filter is clogged. Also after cleaning the carb and refitting it you will need to add vacuum to that fitting. It is a safety devise to shut the fuel off to the carb. In case the rider forgets a small hand vacuum pump from harbor freight will do the job just fine

it really should not matter as long as fuel pressure is the same on both

No you can not eliminate that line. It is a fuel return line for unused fuel the computer returns back to the fuel tank. The computer senses the fuel pressure going to all injectors although the fuel pump can produce more fuel than the computer wants. That is the reason for the third line

this could be a number of problems,check the voltage with a volt meter,not a test light at the fuel pump connection. make sure you have 12V,if so unhook the fuel supply line,turn key to ON not START, and make sure the pump will continue to flow,( obviously cqatch the fuel with a pail,or put a hose on it to pump it into a pail,don't let it leak all over the place.)if the pump continues to flow with out shutting off,your pump,filter,and electrical for your pump is ok.it could be a restriction in the return line,or the regulator may not be functioning.un hook the return line as close to engine as possible,install hose on it and route to a pail to catch fuel,with supply line hooked back up,start van and see if it works,if it keepd shutting off,you've now eliminated return line problems.check the regulator.

It may be something with the carb like a float, valve, or jet problem, but don't rule out vapor lock. Make sure that the fuel lines are protected from the heat of the engine. Sometimes rerouting/shielding fuel lines can make a difference. Just a thought. Best wishes.
