A fuel pump is one of the most important components of your vehicle. It can be quite problematic if your fuel pump breaks down in the middle of your travel. So, before you depart on your journey it is highly recommended that you take your RV to a workshop to ensure that everything is working properly.

There are a lot of problems that your Fuel pump can potentially run into. This is why we will be going over some common RV fuel pump problems and how you can sort them out.

RV Fuel Pump Problems

  1. Fuel Pump Stalling

One of the most common problems you will run into is that your fuel pump will start stalling when the temperatures reach a certain point. You will also notice higher temperatures on the thermometer when you’re having this issue.

Most often than not the actual culprit behind this issue is the fuel pump motor. So, if you have just recently bought the fuel pump replacement then you should have a mechanic take a look at your fuel pump motor.

If it is not working properly then the only option is to get it replaced. Overall, it would be a cheaper alternative because you will not have to pay for the whole fuel pump.

If you’ve had the fuel pump for a long time and changing the motor does not fix the stalling issue, then it is likely that your fuel system has worn out. The only option left in this scenario is to grab yourself a fuel pump replacement and have a mechanic install it for you. This will surely fix the stalling problem for you and you can go on your travels without any issue.

  1. Power Loss

Another quite common issue is that your RV will lose power whenever you’re going uphill or carrying a somewhat heavy load. Your engine will seem like it is shutting down and you’ll lose control over the engine. This problem occurs when the fuel going into the engine is not sufficient.

One of the biggest functions of the fuel pump is to maintain the fuel pressure that is going into the engine. When the pressure is below a certain amount your engine will start losing power and you won’t be able to get your RV to work if there is excessive load inside it.

Sometimes using low-quality fuel can cause your RV to behave like this. So, the first fix you can try is to change the fuel already present in the tank and then try doing some heavy lifting with your RV.

If that does not work then the only option, you’re left with is to get yourself a fuel pump replacement. It can be a bit costly but the new fuel pump will last you several years so you won’t have to worry about changing it anytime soon.

  1. Mileage Issues

As mentioned above the main function of a fuel pump is to supply the engine with an adequate amount of fuel to keep everything running. But if you’re running into mileage issues then it is likely that your fuel pump is injecting more fuel into the engine than necessary.

If you’re constantly having issues with your mileage then you need to get your fuel pump checked immediately. This issue is mainly related to valves in your fuel system which are not opening/closing properly.

This is why there is more fuel getting injected into your engine. This issue can be quite damaging for your engine because all of this excess fuel will leak away.

After consulting a mechanic, you can have your fuel pump fixed or replaced altogether. Make sure to buy the new fuel pump from a reliable brand otherwise you’ll end up facing the same issues again. Doing the proper research can save you thousands of dollars in the long run.

These were some common problems that you might run into with your RV fuel pump. If you’re having any other issues or the mentioned fix is not working for you then we recommend that you go to a workshop and get your vehicle checked properly. This will take the guesswork out of the equation and you’ll be able to pinpoint the exact issue in no time.
