If the fuel lines are backwards, the engine will not run. To check if the fuel lines are backwards, remove the spark plug and look into the cylinder. If you see fuel on the piston, then the fuel lines are backwards.
- Open the hood of your vehicle and locate the fuel lines
- Examine the fuel lines to see if they are labeled with an “IN” or “OUT” designation
- If the fuel lines are not labeled, trace the lines from the fuel pump to the engine to determine which line is which
- The line that goes from the pump to the engine is the “IN” line, and the other line is the “OUT” line
- Once you have determined which line is which, start your vehicle and check for leaks at each connection point
- If there are no leaks, then your fuel lines are installed correctly

Which Fuel Line is the Return Line?
The return line is the fuel line that returns unused fuel back to the tank. It is typically located on the passenger side of the vehicle.
Will a Car Run With the Fuel Lines Backwards?
No, a car will not run with the fuel lines backwards. The fuel system in a car is designed so that the fuel flows from the tank to the engine. If the fuel lines were reversed, the engine would not be able to draw fuel from the tank and would eventually stall.
In addition, running a car with the fuel lines backwards can damage the fuel pump and other components in the system.
What Happens If I Put My Fuel Filter on Backwards?
If you put your fuel filter on backwards, the engine will not run. The fuel filter is designed to only allow fuel to flow in one direction. If you put it on backwards, the fuel will be blocked from reaching the engine.
What Happens If Fuel Line is Kinked?
If a fuel line is kinked, it can cause the engine to run erratically or stall completely. In some cases, it can also lead to a fire.

How to Install Fuel Lines
If you’re installing new fuel lines or replacing old ones, there are a few things to keep in mind. First, always use the correct type of line for your vehicle. Second, be sure to measure the lines carefully before cutting them to length.
Third, when attaching the lines to fittings, use two wrenches to avoid cross-threading. Finally, it’s always a good idea to test the lines before putting everything back together. Here’s a step-by-step guide on how to install fuel lines:
1. Choose the right type of fuel line for your vehicle. There are several different types on the market, so consult your owner’s manual or a reputable automotive parts store for guidance.
2. Measure the fuel lines carefully before cutting them to length.
Once they’re cut, there’s no going back!
3. Attach the fuel lines to their respective fittings using two wrenches (one on the line and one on the fitting). This will prevent you from cross-threading anything.
4 . Test all of the connections before putting everything back together again .
Conclusion
If you’re not sure which way the fuel lines go on your carburetor, it’s important to know how to tell if they’re backwards. Otherwise, your engine will run very poorly or not at all. Here are a few tips:
1. Check the position of the choke lever. If it’s in the wrong position, it’s likely that the fuel lines are backwards.
2. Look at the position of the air filter.
If it’s mounted upside down, that’s another sign that the fuel lines are installed incorrectly.
3. Try starting the engine. If it won’t start, or if it runs very roughly, chances are good that the fuel lines are backwards.
4. Finally, take a look at the carburetor itself.
