Running out of fuel while towing is something many drivers try to avoid at all costs. But what if it happens? Is it really as bad as we think?

Running out of diesel while towing can cause several problems, including engine damage and additional maintenance. The effects depend on the situation, but it's always best to avoid running out of fuel while towing.

It might seem like a minor issue, but letting a diesel run dry while towing can lead to a host of complications, both immediately and long-term. Diesel engines are more complex than gasoline engines, so a dry tank can introduce air into the fuel lines, causing the engine to sputter or stop. In this article, we will take a deeper look at the consequences of running out of fuel while towing, the steps to take to avoid it, and how to minimize potential damage.

What Happens When a Diesel Engine Runs Out of Fuel While Towing?

Running a diesel engine dry can lead to immediate engine failure. If you're towing heavy loads, this could cause a hazardous situation, leaving you stranded and potentially damaging the engine.

When a diesel engine runs out of fuel while towing, it often leads to air entering the fuel lines. This can prevent the engine from starting or cause it to run erratically. Additionally, repeated occurrences could result in costly damage to critical components like the fuel pump.

Running a diesel dry while towing is risky because the engine works much harder than usual. The strain from pulling a heavy load combined with a lack of fuel can cause the fuel system to become compromised. This can result in an increased likelihood of clogging the fuel filters, damaging the fuel pump, or even breaking down internal components. The longer the truck runs without fuel, the higher the chances of serious damage.

What Are the Risks of Running a Diesel Out of Fuel While Towing?

When you’re towing, your engine works harder than normal. That means more fuel is being consumed. Running out of fuel puts extra stress on various parts of the engine. Let’s break down some of the primary risks:

1. Fuel System Damage

A diesel engine relies on pressurized fuel to work smoothly. Once the fuel runs out, air enters the fuel system. The fuel pump struggles to function without fuel, leading to damage or complete failure. Fuel pumps are essential for ensuring that fuel moves properly from the tank to the engine. If damaged, fuel system repairs can be expensive and time-consuming.

2. Clogged Fuel Filters

Diesel fuel filters trap dirt and debris before they can reach the engine. If the fuel level is low or empty, the pump can suck up debris that has settled at the bottom of the tank. This can result in the filters becoming clogged, leading to poor engine performance or breakdowns.

3. Difficult Restarting

It can be incredibly hard to get a diesel engine started after it runs out of fuel. Often, you will need to prime the system or bleed the fuel lines to remove the air. This process can be complex and may require professional help, especially in the middle of a towing job.

4. Engine Overheating

When towing heavy loads, the engine is already under pressure. Running out of fuel adds to the risk of overheating, as the engine can’t receive the proper fuel flow it needs to operate at its optimal temperature. In some cases, this can lead to even more severe damage, such as a blown gasket or warped engine components.

How to Prevent Running Out of Diesel While Towing?

It's always better to take preventative measures than to deal with the consequences of running out of fuel while towing. Here are some steps you can take:

1. Monitor Fuel Levels Closely

When towing, always keep a close eye on your fuel gauge. It’s easy to forget that your consumption rate has increased when towing a heavy load. Try to top up your fuel tank when it’s about a quarter full to avoid any surprises during your journey.

2. Carry Extra Fuel

In some cases, carrying an extra can of diesel may be a smart move, especially if you are towing long distances or in areas with limited access to fuel stations. This way, you have a backup in case you get caught in a situation where refueling isn't immediately available.

3. Know Your Vehicle’s Fuel Range

It’s essential to know how far your vehicle can travel on a full tank, especially when towing. Some vehicles consume significantly more fuel when towing, so knowing your fuel range can help you plan stops ahead of time.

4. Install a Secondary Fuel Gauge

Having a secondary gauge installed can help you monitor fuel usage more accurately. This is especially useful for vehicles that don’t have a precise fuel gauge or if you’re unsure of the vehicle's fuel consumption when towing.

What to Do if Your Diesel Engine Runs Out of Fuel While Towing?

If you’ve run out of fuel while towing, the most important thing is to stay calm. Don’t attempt to start the engine again without addressing the issue first. Here’s a step-by-step process:

First, check the fuel tank to confirm it’s completely empty. Then, assess the situation and, if possible, refuel your vehicle immediately. Once refueled, you may need to prime the fuel system and bleed the lines to get the engine running again.

Step-by-step Guide:

1. Stop Safely: Find a safe place to pull over. If you’re towing, try to stop on a flat surface, away from traffic, and ensure the safety of yourself and others.

2. Check for Fuel: Confirm that the tank is empty. It’s easy to assume there's still some left, especially if your gauge is inaccurate or you're unsure of the tank’s exact capacity.

3. Refuel: If you’re in a position to do so, add fuel to your tank. If you're in a remote location, consider having a spare fuel can with you.

4. Prime the Fuel System: Many diesel engines need to be primed after running dry. Follow your vehicle’s manual instructions for this process. It may require turning the ignition on and off a few times or using a hand primer.

5. Bleed the Fuel Lines: If your vehicle requires it, you may need to bleed the fuel lines to remove any air trapped in the system.

6. Start the Engine: Once you’ve refueled and primed the system, attempt to start the engine. It may take a few attempts before the air is cleared and the engine starts running smoothly again.

7. Seek Professional Help: If you’re unable to restart the engine or feel that there’s damage, seek help from a mechanic or roadside assistance.

Conclusion

Running out of fuel while towing is not ideal, and it can lead to costly damage if not handled properly. While it’s not always avoidable, taking precautions can reduce the risk and ensure that you’re not left stranded on the road.
