Changing The Fuel Filter On An Onan 5500 Generator: Step-By-Step Guide

The Onan 5500 generator has two fuel filters, one before the fuel pump under the generator, and one below the carburettor. The latter has been known to leak, and Onan has addressed this issue by recommending the use of a new filter before the fuel pump and an adapter to replace the filter under the carburettor. This adapter, part number A026E529, is screwed into the carburettor, and the fuel hose is then slipped over it and clamped. The new filter is part number 0149-2341-01.

The Onan 5500 has two fuel filters

To replace the old filter with an adapter, you will need to buy the adapter with part number A026E529. You can then screw this into the carburettor where the old filter was, and attach the gas hose.

The new primary fuel filter has the part number 0149-2341-01. This should be placed before the fuel pump.

The old filter #0149-2629 leaks fuel at the seams

If your old filter #0149-2629 is leaking fuel at the seams, you should replace it with a new filter, part number 0149-2341-01. This is because the old filter is prone to leaking, which poses a fire hazard.

To replace the old filter, first, make sure you have the correct replacement filter, part number 0149-2341-01. You will also need an adapter, part number A026E529, which you can purchase from Onan.

• Remove the clamp at the fuel hose at the inlet of the fuel filter.
• Remove the fuel hose from the fuel filter.
• Use an 11/16-inch deep socket to remove the old fuel filter.
• Thread the new adapter, part number A026E529, into the carburetor by hand until the thread sealant engages, and then tighten it further by hand for 1-1/2 turns.
• Reinstall the fuel hose and install a new clamp (part number e5r03-1951-08 or similar) to secure the hose.

By following these steps and using the correct replacement parts, you can address the issue of fuel leakage at the seams of the old filter #0149-2629 on your Onan 5500 generator.

Onan recommends a new filter before the fuel pump

The Onan 5500 generator has two fuel filters, one before the fuel pump under the generator and one below the carburetor. The fuel filter below the carburetor has been known to leak fuel at the seams. As a result, Onan recommends putting a new filter before the fuel pump and removing the filter under the carburetor.

To do this, you will need to purchase an adapter with the part number A026E529 and a new filter with the part number 0149-2341-01. First, remove the clamp at the fuel hose at the inlet of the old secondary fuel filter. Then, remove the fuel hose from the fuel filter. Finally, use an 11/16-inch deep socket to remove the fuel filter.

Now, you can install the new adapter. Thread the replacement fitting part by hand until the thread sealant engages, and then turn it an additional one and a half times. Reinstall the fuel hose and install a new clamp.

The primary fuel filter (the one before the fuel pump) should be changed out at normal service intervals or when the generator is brought in for a fuel filter change. This filter is easily accessible from underneath the RV. To change it, first, remove the fuel line from the fuel filter. Be sure to plug or pinch off the fuel line to prevent leakage. Then, remove the rubber grommet from the oval hole to reveal the fuel filter. Use a deep well 9/16" socket to slowly turn the old filter counterclockwise and unscrew it from the fuel pump. Put some high-temperature thread sealant at the base of the threads on the new fuel filter. The new fuel filter will fit inside the oval hole, allowing it to connect to the fuel pump. Tighten the new filter with a socket, being careful not to overtighten. Finally, replace the rubber grommet and fuel line.

An adapter is needed to replace the filter under the Carb

The Onan 5500 generator has two fuel filters: one before the fuel pump under the generator, and one below the carburettor. The latter has been known to leak fuel at the seams, and Onan has addressed this issue by recommending the use of an adapter instead of a filter. The adapter, with the part number A026E529, is screwed into the carburettor, and the fuel hose is then slipped over a barbed fitting on the adapter and clamped into place. This adapter is long enough that the existing fuel hose will still reach it.

To install the adapter, first, remove the clamp at the fuel hose inlet of the old fuel filter. Then, remove the fuel hose from the filter and use an 11/16-inch deep socket to remove the filter itself. Thread the new adapter on by hand until the thread sealant engages, then turn it an additional one and a half times. Finally, reinstall the fuel hose and a new clamp.

The new primary fuel filter, which should be placed before the fuel pump, has the part number 0149-2341-01.

The new primary fuel filter is 0149-2341-01

To change the fuel filter on an Onan 5500 generator, you will need to purchase the new filter, which is an affordable and simple fix for generator performance issues. The old filter is located under the generator and can be accessed from underneath.

The first step is to remove the clamp at the fuel hose inlet of the old filter. Next, remove the fuel hose from the filter. Then, use an 11/16-inch deep socket to remove the old filter. Now you can install the new primary fuel filter, part number 0149-2341-01. Thread the new filter onto the fitting by hand until the thread sealant engages, and then turn it an additional one and a half times. Reinstall the fuel hose and secure it with a new clamp.

The new primary fuel filter is a high-quality, authentic Onan product that is easy to install and will improve the performance of your generator.
