We’ve put together this quick-fix guide for RV fuel pump problems to ensure you arrive at your destination safely and without your fuel pump malfunctioning.

Throughout the post, we’ll discuss the symptoms you’ll encounter, the possible problems that may be causing them, and possible treatments.

So, before we start, let’s go through everything we’ll need in the following.

Things You’ll Need

What Do RV Fuel Pump Problems Cause?

Faulty RV fuel pumps can be a significant source of performance and drivability concerns with your RV. Furthermore, this might cause other issues for your RV.

If the air-to-fuel ratio is wrong or the cylinder is not receiving fuel, the pistons will not fire. It might result in your RV not starting at all, causing mileage or efficiency concerns.

As a result, it’s best to address RV fuel pump problems as soon as you see them.

The Symptoms and The Problems Behind Them

Most issues have a structured solution that you can implement immediately. But when your RV fuel pump fails, one thought often comes to mind.

“What do I need to do here?”

It can be answered in a single sentence. Examine the symptoms to identify the issue that needs to be resolved. 

So, let’s look at some of the symptoms that might occur with RV fuel pump problems, as well as some easy remedies.

Whining Fuel Tank

It is one of the first signs that an RV fuel pump is malfunctioning. While operating, the pump begins to make a loud whining noise. But generally, it’s meant to hum softly.

It indicates an issue such as inadequate fuel, a faulty pump, or tainted fuel within the system. On the other hand, a whining fuel tank is quite simple to repair.

You may either add gasoline or replace the pump to remedy one of these RV fuel pump problems. You can also replace the gas if you suspect it is tainted.

Difficulty Starting The Fuel Pump

Another sign you may have is difficulties starting up. When the ignition is turned on, your RV’s fuel pump operates continually.

It may cause them to wear out or deteriorate over time. Weakened fuel pumps may continue to pump fuel, but your RV will struggle to start due to low pressure.

The issue here is a faulty gasoline pump. So, the ideal approach would be to replace the gasoline pump. It will ensure that the remainder of the RV’s systems remains in good working order.

Stalling At Excessive Temperatures

This symptom arises from a variety of issues within your vehicle. However, you must solve the problem if you see excessive temperatures on your RV’s thermometer.

The increasing temperature might signal a problem with the motor in the RV fuel pump. If this problem persists, it may indicate that the RV fuel pump is aging out over time.

The ideal solution would be to diagnose the pump precisely. Replace the gasoline pump motor if it isn’t operating. Otherwise, completely replace the gasoline pump.

Sudden Loss of Power During Stress

A malfunctioning RV fuel pump might also be detected when it falls under a stressful scenario or accelerates. Driving uphill or carrying a significant weight are both stressful circumstances.

The engine tends to shut down in these circumstances. It happens due to the compromised parts’ inability to keep up with the RV’s fuel consumption. As a result, the RV cannot sustain power and complete the work.

The RV loses power, so the fuel pump can no longer manage fuel pressure. As a result, the optimum remedy would be to replace the gasoline pump.

Low Gas Mileage

This sign indicates that your RV’s engine is being over-filled. Excess oil is not remaining in storage. It dries up.

The cause of this is a defective valve in your fuel pump. Because the valve isn’t functional, it’s not opening. It allows more gasoline to enter the engine than is necessary.

In this scenario, you must repair the gasoline pump to restore the RV’s perfect mileage.

Car Not Starting

Finally, we get to the most severe symptom on our list. This problem occurs when your fuel pump fails to start.

The RV will not start no matter how many times you turn the keys since it does not have enough fuel to start the engine.

However, this no-start issue might also be due to anything else. To correctly conclude this one, you’ll need to diagnose your RV.

Furthermore, gasoline pumps are standard on all RVs and are built to last. They degrade and eventually cease to function.

As a result, it is pretty unusual for a gasoline pump to fail. Aside from mileage, another cause of fuel pump failure is maintaining the gasoline at less than 14 percent of the fuel tank’s capacity.

So, replacing the RV fuel pump is your best choice here. But first, contact a competent mechanic and have the entire RV inspected.
