Whether or not you need a fuel filter for your Buddy Heater depends on the type of hose and tank you are using. If you are using a low-pressure quick-connect hose, you do not need a filter. However, if you are using a rubber hose and a 20-pound tank (or larger), the rubber can deteriorate and give off an oily liquid residue under high pressure, which can clog your heater. In this case, a fuel filter is recommended to prevent clogging and ensure proper fuel flow. Some sources suggest that a regulated hose made from better material that does not deteriorate under pressure eliminates the need for a filter, while others recommend always using a filter as a low-cost insurance policy. Ultimately, it is up to the user to decide whether or not to use a fuel filter based on their specific setup and preferences.

What You'll Learn
The function of a fuel filter
Some diesel engines use a bowl-like design to collect water at the bottom of the filter, as diesel floats on water. The valve at the bottom of the bowl can be opened to drain the water, leaving only the fuel.
In the context of a Buddy Heater, opinions vary on the necessity of a fuel filter. Some users claim that when using a low-pressure quick-connect hose, a fuel filter is unnecessary. However, others recommend using a fuel filter when connecting to alternative 5 or 20-pound tanks instead of the standard 1-pound propane tanks to avoid intermittent functioning issues. It is worth noting that the filter is more crucial for the hose than specifically for the fuel in this case.
The decision to use a fuel filter with a Buddy Heater may also depend on the type of hose used. Standard hoses may leech oils, causing clogging in the heater, whereas Mr. Heater sells special hoses that do not leech and are less likely to gum up the system. Therefore, while a fuel filter is not always mandatory for a Buddy Heater, it can be a worthwhile precaution to prevent potential issues, especially when using certain types of hoses and fuel tanks.

Whether a fuel filter is necessary
The main issue with using a Buddy Heater is the potential for oily substances to be squeezed from the rubber of some hoses under high pressure, which can then get pulled along with the propane flow and clog the heater. This problem can be avoided by using a regulated hose, which never applies high pressure to the hose and therefore does not require a filter. If you are using a low-pressure quick-connect hose, you do not need a filter.
Some users have also reported that their Buddy Heaters worked fine without a filter, even when using larger tanks, and that the filters caused issues with their heaters. However, others consider the filters a low-cost insurance policy and would rather add a few extra bucks for more confidence.
Mr. Heater, the manufacturer of the Buddy Heater, recommends using a fuel filter with their product. Their website describes the fuel filter as an oil trap that prevents oily particulates from clogging the fuel flow. They also sell special hoses that don't leech and gum up the system, which can be used without a filter.

The impact of hose type
Mr. Heater offers a range of hoses, including the 10' buddy hose, which is designed to withstand high-pressure propane flow without leaching any oily contaminants. This specific hose does not require a fuel filter because it is constructed to prevent the release of oils and plasticizers. However, other hoses used with the Buddy Heater system may require a filter to capture these contaminants and prevent clogging or flow issues.
The fuel filter acts as an oil trap, ensuring that the oily particulates stick inside it, thereby filtering the fuel before it reaches the heater. This is particularly important when using rubber hoses that are susceptible to leeching oils under high pressure. The filter helps maintain consistent fuel flow and prevents blockages in the heater's lines.
It is worth noting that the hose type and quality can vary, and not all hoses are created equal. Some users have reported issues with certain hoses, even when using a fuel filter. Therefore, it is recommended to follow the manufacturer's guidelines and choose hoses specifically designed for the Buddy Heater, such as those offered by Mr. Heater, to ensure compatibility and safe operation.
Additionally, the type of fuel and connection can also influence the need for a fuel filter. For example, when using commercial propane or natural gas, a fuel filter may not be necessary. However, when connecting to alternative fuel sources or larger tanks, a fuel filter can help prevent intermittent issues or blockages.

High pressure and oily residue
Oily residues can accumulate in fuel filters, pressure regulators, fuel mixers, or control solenoids. LPG is particularly susceptible to this issue, which can lead to corrosion and blockages. In the context of a Buddy Heater, the need for a fuel filter depends on the type of hose and fuel tank being used.
If you are using a braided steel cable or a low-pressure quick-connect hose with a 1-pound propane tank, a fuel filter is typically not necessary. However, if you are connecting to an alternative 5 or 20-pound tank, a fuel filter is highly recommended to prevent intermittent issues and blockages.
The primary purpose of a fuel filter is to trap contaminants and ensure the smooth flow of fuel. When there is a build-up of oily residue or other impurities, the filter can become clogged, restricting the flow of fuel and impacting the performance of the heater.
High pressure is a contributing factor to the presence of oily residues in fuel filters. Excessive pressure can force oil through the PCV valve and into the air intake system, leading to potential clogging and engine performance issues. Regular maintenance, including the replacement of oil passages and filters, is crucial to mitigate this problem.
Additionally, the type of air filter used can influence the presence of oily residues. Some aftermarket air filters are oiled from the outside before use to enhance particle trapping. While this is normal and intended, it is important to follow the manufacturer's recommendations for replacement to avoid excessive oil build-up and potential engine issues.
To summarise, high pressure, in combination with other factors such as oil passage blockages and improper maintenance, can contribute to the accumulation of oily residues in fuel filters. Regular maintenance, including the use of appropriate hoses and filters, is essential to prevent clogging and ensure the optimal performance of Buddy Heaters and similar equipment.
