The Stihl BR600 is a backpack blower that has been known to have issues with its fuel line. The OEM line is often too short, making it difficult to replace the fuel filter, and the line from the carb to the primer bulb can be too loose, causing leaks. To address these issues, some users have recommended purchasing a new fuel line hose kit, such as the Proline® kit, which fits the Stihl BR600 model. Others have suggested measuring the internal diameter of the line and purchasing a new line with a smaller diameter, or cutting the existing hose back by 10mm to create a tighter fit. While some users have expressed dissatisfaction with Stihl products due to these issues, others have found solutions, such as using a coat hanger to push the line forward and then replacing the filter.

What You'll Learn
Stihl BR600 fuel line length
The STIHL BR600 is a backpack blower that uses a fuel line hose to transport fuel from the tank to the engine. The fuel line hose is a critical component of the BR600's fuel system, which also includes the carb, primer bulb, and tank.
The STIHL BR600 fuel line length is not specified by STIHL or any third-party vendors. However, the fuel line is designed to fit the BR600 specifically, ensuring it is the correct length and diameter. The fuel line kit for the BR600 is available as an OEM replacement part, with some users opting to purchase this instead of measuring and cutting a new hose to fit.
Some users have reported issues with the original fuel line, stating that it is not tight enough on the carb nipple, causing leaks. This has prompted some to seek alternative solutions, such as measuring the internal diameter of the line and purchasing a new hose with a smaller diameter. However, others have suggested that sealant may not be necessary and that a tight fit should be the primary goal.
The BR600 fuel line kit, part number 4282-007-1014, is available from several vendors and has received positive reviews for its exact replacement length, perfect fit, and helpful installation instructions.

Hose diameter
The STIHL BR600 backpack blower is a powerful machine, but some users have reported issues with the fuel hose line. The problem appears to be centred around the connection between the hose and the carb nipple, with the hose not fitting tightly enough, resulting in leaks. This issue has caused frustration among users, as it leads to gas/oil spills after a few minutes of running the machine.
To address this problem, it is important to determine the correct hose inside diameter. However, the exact inside diameter of the hose for the STIHL BR600 has not been explicitly stated. Users are advised to physically measure the internal diameter of the line and then convert it to fractions and decimals. This measurement can then be used to select a replacement hose with a corresponding inside diameter.
It is recommended to order a new line directly from Stihl to ensure the correct length and diameter, guaranteeing a tight fit without the need for sealants. While waiting for a replacement, a temporary solution suggested by users is to cut the existing hose back by 10mm to create a tighter fit on the barbs. However, it is important to note that this may not be a permanent fix, as clips or ties might not work in the tight space around the bulb.
To prevent leaks, users should focus on achieving a secure fit rather than relying on glues or sealants. A non-hardening aviation form-a-gasket product can be used, but the primary goal should be to ensure the hose is properly sized and fitted to the carb nipple. This will help avoid the inconvenience and mess of fuel leaks during operation.

Fuel filter replacement
The Stihl BR600 is a backpack blower. It is a common complaint that the fuel line is too short to replace the fuel filter through the filler neck. The dealer recommends removing the fuel filter through the top of the fuel tank. There is a plug in the top of the tank that holds the fuel line and must be pulled out of the tank, along with the fuel filter.
To replace the fuel filter, first, check the inlet prefilter screen located under the diaphragm base cover. Also, check the diaphragm for any small tears or cuts or excessive sag. If all appears to be okay, a simple fuel cleaner addition of 2 ounces with fresh fuel will likely resolve the problem. Leave the fuel filter in a small container of cleaner overnight along with the new fuel mixture within the saw, then blow it out with compressed air and reinstall.
If the fuel filter still needs to be replaced, a coat hanger can be used to push the line forward and then grabbed with pliers to put the new filter on. Alternatively, a sharp razor blade or similar tool can be used to taper one end of the tubing back by about 3-4 inches. Poke a small hole in the pointed end, insert a thin wire, then thread the wire up into the hole in the tank where the old line was, and out through the fill hole. The wire allows the tubing to be pulled into the tank. A little clean oil on the tubing will help with the insertion. Pull the tube through, cut off the tapered end, install the new fuel filter, and connect the hose to the other connection. Be careful not to cut the nipple end too short.
There are also various fuel filters available on Amazon that fit the Stihl BR600.

Sealant type
The Stihl BR600 backpack blower is known to have issues with its fuel line, which can be too short or loose-fitting, resulting in leaks. While some users recommend using a sealant, such as Permatex Non-Hardening Aviation Form-A-Gasket, along with a zip tie to secure the connection, others advise against relying on glues and suggest focusing on ensuring a tight fit.
To address the issue, it is recommended to measure the internal diameter of the hose and choose a replacement hose with a slightly smaller diameter to ensure a snug fit. It is also suggested to consider purchasing a new fuel line, such as the Tygon fuel line, which can be bought from local outdoor power equipment dealers or repair shops.
The Stihl BR600 fuel line is a common point of discussion among users, with many seeking advice on how to address leaks and connection issues. While sealants can be used as a temporary solution, the focus should be on finding the correct hose diameter to ensure a tight and secure fit, preventing leaks and ensuring the safe and efficient operation of the equipment.
It is important to note that the Stihl BR600 fuel system operates with pressurised fuel, and understanding the pressure, suction, and flow dynamics is crucial for proper maintenance and troubleshooting. Therefore, while sealants can be a quick fix, ensuring the correct hose fit and diameter is the recommended approach to address fuel line issues in the Stihl BR600 backpack blower.

The OEM line on the STIHL BR600 has been criticised for its loose fit, resulting in leaks. The hose from the carb to the primer bulb does not fit tightly enough on the carb nipple. As a result, users have had to cut the hose and measure the internal diameter to find a suitable replacement.
To address the issue, it is recommended to purchase a new fuel line hose kit that ensures proper fitment. The Proline® fuel line hose kit for Stihl BR600 blowers offers a 120-day warranty and is known to fit the BR600 model perfectly. Alternatively, users can opt to buy a Stihl fuel line from an authorised dealer, ensuring they get the correct length and diameter for their machine.
While some users have suggested using sealants to address the loose fit, others advise against relying solely on glues. It is recommended to focus on achieving a tight fit, and if necessary, using a tie wrap to secure the connection. Additionally, it is suggested to replace the push primer bulb along with the fuel line to ensure a durable solution.
