Why is fuel not getting to the carburetor?
No fuel at your carburetor can be caused by many things. It could be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Another logical cause could be the fuel pump. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.
How do I know if my fuel return line is clogged?
Symptoms of a Bad or Failing Fuel Return Hose
- Strong fuel odor, engine misfires, and decreasing power. One of the first symptoms of an issue with the fuel return hose is an excessive fuel smell.
- Carburetor flooding, engine stalling, and hard starting.
- Fuel leaks.
How do you tell if a carburetor is clogged?
Four Signs Your Carburetor Is Failing
- Engine Performance Reduction. As mentioned above, combustion starts and keeps your engine running.
- Black Exhaust Smoke. You shouldn’t see black smoke coming out of your exhaust pipe even if you drive a diesel.
- Engine Backfires or Overheats.
- Starting Difficulty.
What causes a blockage in the fuel line?
We’ve had problems with two hoses in the past three years. A blocked outboard fuel line prevents fuel from getting to the motor. It generally starts with a partial blockage, where playing around with the fuel hose and pumping the primer bulb will get the motor to start or keep it running.
What to do if there is no fuel in the tank?
Crank over engine – if there is no fuel discharge from the fuel line, check for kinked or bent lines. Disconnect fuel line at tank and blow out with air hose, reconnect line and check again for fuel discharge.
Why is ethanol bad for the fuel line?
Ethanol is a problem for a lot of reasons, not the least of which is fuel line decomposition, including delamination. Some of those little pieces can end up clogging jets leading to carb rebuilds. Phase separation leaves globs of ethanol in the fuel that the engine cannot run on.
What to do if no fuel is coming out of the Idi?
Never crank an IDI for longer than 15-seconds at a time. Hold a cup underneath the depressed valve to catch any spraying fuel. I like to wear safety glasses, just in case a drop or two sprays out of control. For the most part, if there is fuel, it will lightly dribble out of the valve.
