What if your RV fuel pump started making some loud noise while you’re on the road? That can be pretty scary, especially if you still have a long way to go.
So, you need a quick fix that can make sure that your RV doesn’t stop running before you reach your destination. It’s all available at the click of a button, right?
But, here’s the catch:
Finding the perfect quick fix guide can be quite the challenge. If that’s the problem you’re facing, you’ve stumbled upon precisely what you need.
We have prepared this quick fix guide on RV fuel pump problems to make sure you reach your destination safe and sound without your fuel pump failing.
Throughout the article, we’ll tell you about the symptoms you’ll find and the probable problems causing them and possible solutions.
So, before we jump right into it, let’s check out what we’ll need in the next section.
Things You’ll Need
What Do RV Fuel Pump Problems Cause?
Faulty RV fuel pumps can be a significant pain that causes performance reduction and drivability issues with your RV. Moreover, this can lead to other problems for your RV as well.
If the air ratio is off or the cylinder’s not getting the fuel, then pistons won’t be firing. This might lead to your RV not starting at all, let alone cause mileage issues or inefficiencies.
So, it’s wise to fix the problems the moment you notice the symptoms.
The Symptoms and The Problems Behind Them
Most problems have a systematic solution that can fix them pretty quickly. But when your RV fuel pump starts acting up, one question always comes to our mind.
“What do I have to fix here?”
This can be answered in one line. Check the symptoms, and you’ll find the problem that you have to fix. So let’s see the kind of symptoms we can face with RV fuel pumps, with quick fixes.
Whining Fuel Tank
This is one of the first symptoms that an RV fuel pump shows when it has a problem. The pump starts making a loud whining noise while running. But normally, it’s supposed to hum quietly.
This shows a problem like insufficient fuel, a damaged pump, or contaminated fuel inside the system. However, a whining fuel tank is pretty easy to fix.
To solve this problem, you can add some fuel or change the pump itself. Or, you can change the fuel already if you think it’s contaminated.
Difficulty Starting The Fuel Pump
One other symptom that you can face is difficulty starting up. The reason behind it is that your RV fuel pump runs continuously when the ignition is on.
This might lead to them wearing out or weakening over time. Weakened fuel pumps might keep pumping fuel, but your RV will face considerable difficulty when starting for low pressure.
The problem here is a weakened fuel pump. So, the best solution here would be to change the fuel pump itself to make sure the rest of the RV’s systems stay healthy.
Stalling At Excessive Temperatures
This symptom appears for multiple problems within your vehicle. But, it’s important that you address the problem when you see high temperatures on your RV’s thermometer.
The rising temperature might indicate a problem in the RV fuel pump’s motor. If this problem continues, it can mean that the RV fuel pump is wearing out with time.
The best way to solve this would be to diagnose the pump accurately. If the fuel pump motor isn’t working, replace it. Otherwise, replace the fuel pump altogether.
Sudden Loss of Power During Stress
You might also get an indication of a bad RV fuel pump when it gives in during stressful situations or while accelerating. Stressful situations include driving uphill or carrying a heavy load.
In this case, the engine tends to shut down due to the weakened parts’ inability to keep up with the RV’s fuel demands. For this reason, the RV can’t maintain power and finish the task.
The RV fails to maintain power, which means the fuel pump can’t regulate fuel pressure anymore. So, the best solution would be to replace the fuel pump itself.
Low Gas Mileage
This symptom means that your RV’s engine is getting filled up more than necessary. Excessive oil does not remain stored. It leaks away.
The problem behind this would be a faulty valve in your fuel pump. Due to the valve not working, it’s not opening, which leads to more fuel pouring into the engine than necessary.
So, in this case, you have to get the fuel pump fixed to get the RV back on its ideal mileage again.
Car Not Starting
Lastly, we have the most severe symptom on our list. This issue comes up when your fuel pump is in a no-start condition.
No matter how many times you turn the keys, the RV won’t turn on because it’s unable to get enough fuel to kick into the ignition.
However, this no-start condition might be for some other reason as well. So you’ll need to diagnose your RV to conclude this one accurately.
Moreover, fuel pumps are found on all RVs and are made to last. And with time they wear out and stop working.
So, it’s not uncommon for a fuel pump to stop working. Other than mileage, another reason behind the fuel pump failure is keeping the fuel at less than ¼ of the fuel tank’s capacity.
So, your best bet here would be replacing the RV fuel pump. But call a professional technician and get the whole RV checked first.
