Where Is The Rv Generator Fuel Line Hooked Up

The fuel line for an RV generator is typically connected to the onboard tank. The process of connecting the fuel line depends on the specific type and make of your generator, as well as other factors such as whether it runs on diesel or gasoline. Generally speaking, you will have to remove any cap from the fuel port before attaching one end of a rubber hose to it while connecting the other end to your onboard gas tank.

You then need to secure both ends with clamps and turn on the power switch located near either end of your RV’s fueling system in order for it to be operational.

The RV generator fuel line is hooked up to the tank of the recreational vehicle, typically on one side. This allows for easy access and refilling when needed. In some cases, it may also be connected directly to a gas station pump or other external source so that you can quickly refuel your RV’s generator in case of an emergency situation.

Onan Generator Fuel Line Size

When it comes to the fuel line size for an Onan generator, you will want to make sure that you use a 5/16 inch fuel line. This is important because this size of fuel line is specifically designed for the Onan generator model and ensures your generator gets just the right amount of necessary fuel. It is also important to note that if you are connecting multiple generators together, then it’s recommended to use a 3/8 inch fuel hose when doing so.

Onan 5500 Fuel Line Size

The Onan 5500 generator requires fuel line size of 3/8″ to ensure proper flow and performance. It is important to use the appropriate size fuel line in order to prevent any blockages or other issues that could arise from using an incorrect size. Additionally, a clogged fuel line can cause the engine on your generator to run inefficiently and potentially damage it over time.

Make sure you always use the correct fuel line size when replacing parts for your Onan 5500 generator!

Onan Generator Not Getting Fuel

If your Onan Generator is not getting fuel, the first thing to check is whether or not the fuel tank has enough fuel in it. If there is not enough fuel, make sure that you fill up the tank with fresh gasoline and add an appropriate amount of oil as recommended by Onan. Additionally, check the air filter on the generator to ensure that it’s clean and clear of debris.

Finally, verify that all wiring connections are secure and free from corrosion.

Onan Generator Fuel Pump Replacement

Replacing the fuel pump on your Onan generator is a straightforward process that can be done at home with minimal tools. First, make sure to disconnect the negative battery cable. Then drain the existing fuel from the tank and remove it from its mounting location.

After that, you’ll need to unscrew and remove any connections attached to the old fuel pump before carefully removing it from its housing. Finally, attach all of your new components and fill up with fresh gasoline or diesel before turning it back on for testing purposes.

Where Do Fuel Lines Connect?

Fuel lines connect to the fuel tank and run along the frame of your vehicle, leading up towards the engine. Depending on where you’re located, they may also be referred to as gas lines or petrol lines. The main purpose of fuel lines is to transfer gasoline from your fuel tank into the engine so it can power your car.

Fuel line connectors are generally made out of metal or plastic and attach onto both ends of a piece of tubing which carries liquid fuel from one place to another. These connectors can come in several different shapes and sizes depending on their application; for example some vehicles might have a few small-diameter tubes that feed directly into an injector rail while others might use larger diameter hoses connecting each cylinder bank with a separate connector attached at each end. In addition, these types of connections need to be properly sealed off in order for them not to leak any combustible liquid and cause potential damage or fire hazards near the engine bay area.

Where is the Fuel Line Located?

The fuel line is one of the most important components in a vehicle’s engine, as it carries fuel from the gas tank to the engine. It is usually located on or near the firewall, underneath the hood of your car. The fuel line can be made up of rubber hoses and metal tubes that are connected together with clamps or fittings.

In order to access this part, you’ll need to remove some other components such as air intake parts and plastic covers. Once these have been removed, you should be able to identify where your fuel lines are located; they’re typically a few inches away from each other and will have a black color. If you suspect there may be an issue with your fuel line then it would be wise to take it into a mechanic for further inspection right away – any potential leak could result in dangerous gases being released into your vehicle’s cabin which could cause serious health problems if inhaled by passengers.

How Does Rv Generator Get Fuel?

An RV generator is a great way to have access to electricity while camping or enjoying the outdoors. But, just like any other type of engine, it needs fuel in order to run. There are several different types of fuels that you can use with your RV generator, depending on what type of generator you have and what kind of fuel availability is available in the area where you’re camping.

The most common type of fuel for an RV generator is diesel. This fuel option tends to be more reliable than gasoline because it does not vaporize as quickly and provides a cleaner burn when compared to gasoline. Additionally, diesel generators also tend to cost less upfront and last longer than their gasoline counterparts.

Propane powered generators are another popular choice for RVs since propane tanks can easily be refilled at campgrounds or even from home if necessary. Propane has many benefits over traditional fossil fuels such as being non-toxic, having no odor or smoke emissions, and providing quiet operation due to its low combustion noise level.

Why Wont My Generator Work in My Rv?

Having a generator that won’t work in your RV can be a frustrating experience. It’s important to understand why it isn’t working, so you can make the necessary repairs or purchases to get back on track. Depending on the type of generator and its age, there are several potential reasons why it may not be operating properly in your RV.

One common problem is inadequate fuel supply; if the fuel tank is empty or near empty, then the generator will not generate any power. Similarly, if there are blockages in the fuel line preventing adequate amounts of gasoline from reaching the engine, this could also cause problems with starting and running. Additionally, an old spark plug may need to be replaced as they will weaken over time and no longer produce enough power for ignition or continued operation once started.

Lastly, some generators require regular maintenance such as oil changes which must be performed at least every few months depending on usage; failing to do so could lead to damage of internal components and prevent proper functioning when needed most. By understanding these potential issues causing your RV’s generator from working properly, you can take steps towards getting back on track quickly!


This blog post has provided a thorough explanation of the RV generator fuel line, including what it is and how to hook it up. It’s important to make sure that your RV generator fuel line is set up correctly in order to ensure that your vehicle runs safely and efficiently.
