Pump sprayers are a convenient way to apply pesticides, herbicides, and other liquids. However, it is not advisable to put diesel fuel in a pump sprayer due to the potential damage it can cause to the equipment. Diesel fuel can ruin spray motor seals and other components, leading to costly repairs or replacements. While some individuals have reported using diesel fuel in pump sprayers with varying degrees of success, it is generally recommended to use alternative fuels or dedicated diesel-compatible sprayers to avoid any potential issues.

What You'll Learn
Pump sprayers designed for diesel fuel exist
Some pump sprayers that are designed for diesel fuel include the Wylie Diesel Spot Sprayer and the 35C Hand-Held Compression Sprayer from Sprayers Plus. The Wylie Diesel Spot Sprayer is a spot sprayer that is compatible with diesel as a chemical carrier. The tank, fittings, hose, and pump are all designed for diesel, and the sprayer is powered by a 12-volt Remco pump with a maximum output of 1.8 GPM. The 35C Hand-Held Compression Sprayer is designed for construction chemicals and tougher situations, including diesel. It features a chemical-resistant hose that is impervious to the solutions and chemicals it is approved for, as well as a pressure relief valve for safety.
In addition to these purpose-built diesel sprayers, some people have reported using cheap hand pump sprayers with diesel fuel without any problems. These sprayers are typically replaced every few years, as they can get very nasty from the diesel fuel. Some brands mentioned include Chapin, Atwoods, Solo, and Rural King. However, it is important to note that not all cheap sprayers will work with diesel fuel, and the seals on common garden-type sprayers may fail if used with diesel.
When using diesel fuel in a pump sprayer, it is important to follow the manufacturer's instructions and take the necessary precautions to avoid damage to the sprayer or injury to the user.

Diesel fuel can damage seals and o-rings in some sprayers
While it is technically possible to use diesel fuel in a pump sprayer, it is not recommended, as it can damage the sprayer's seals and o-rings. Some pump sprayers are made to handle diesel fuel and other petroleum products, but cheaper sprayers with plastic components are more susceptible to damage.
Diesel fuel can cause seals in cheap garden sprayers to swell up, and it can also ruin spray motor seals. It can also melt parts of the packings and cause the pump to wear out faster. As such, it is advisable to use a pump sprayer designed for diesel fuel or to buy a cheap hand pump sprayer that can be disposed of after use.
If you intend to use a pump sprayer for diesel fuel, look for one with Viton seals, as Viton offers better resistance to chemical attack by oils. NBR or vinyl hoses can soften when exposed to diesel fuel but may still work for a season.
To avoid damaging your pump sprayer, you can use alternatives such as cooking oil for emulsion formation or a mix of diesel and motor oil. It is also important to clean your pump sprayer after each use with a good detergent and water.

Mixing diesel with other substances can reduce damage
Mixing diesel with other substances can cause serious damage to engines and machinery. However, in some cases, the impact can be reduced by mixing diesel with the right substances and taking certain precautions.
One of the most common issues with mixing diesel is when it is accidentally mixed with gasoline in a vehicle's fuel tank. Diesel fuel is heavier than gasoline, so it sinks to the bottom of the tank, leading to the injection of both fuels into the engine. This can result in incomplete combustion, characterised by large amounts of black smoke. The vehicle's computer tries to compensate by adjusting the fuel-air mixture, leading to reduced power and performance. Additionally, the diesel fuel may not burn completely, leaving deposits on pistons, valves, and spark plugs, causing serious damage over time. Mixing gasoline and diesel can also lower the octane rating of the gasoline, affecting the fuel's ability to ignite at the right time and potentially damaging pistons and rods.
However, mixing diesel with other substances, such as motor oil or lubricants, can be done for specific purposes. For example, some people mix diesel with motor oil to treat and protect wooden surfaces, such as the boards on a flatbed. In this case, the ratio of diesel to motor oil is important, with recommendations ranging from a 50/50 mix to a 2 parts diesel to 1 part motor oil ratio. Additionally, when using a sprayer, it is crucial to use one that is diesel-compatible to avoid damaging the sprayer's seals and motor.
Another instance where mixing diesel with other substances can be beneficial is in the case of storing pumps for long periods. It is recommended to remove the fluid section of the pump and dunk it into a bucket of light motor oil, such as 10w30 or 10w40. This helps prevent rust and keeps the o-rings and packings in good shape.
It is important to note that mixing diesel with the wrong substances can have disastrous consequences. For example, mixing diesel with DEF (AdBlue) can ruin the entire fuel system and possibly an engine if not addressed promptly. Similarly, water or sugar mixed with diesel can cause significant engine damage, including cylinder wall and piston ring destruction.

Some people use cheap pump sprayers with diesel and throw them away
It is not advisable to put diesel fuel in a pump sprayer. The diesel will ruin your spray motor seals and other parts of your pump. It will also make your pump wear out faster.
However, some people do use cheap pump sprayers with diesel and throw them away. If you are going to use a pump sprayer with diesel, it is recommended to buy a cheap hand pump sprayer and then throw it away after use. Some people also recommend using a pump sprayer that is designed for diesel.
One user recommends using a 3.5-gallon Chapin 1949 concrete form board sprayer. Another user suggests using a backpack pump sprayer. It is important to note that the cheap tanks might come with some kind of NBR or vinyl hose, which will soften but still work for a season. Therefore, it is recommended to use nitrile or Viton seals, which hold up better to diesel and offer better resistance to chemical attack by the oils in the fuel.
Additionally, it is important to empty and clean your pump after each use with a good detergent and water.

Diesel fuel can be used as a carrier for Garlon 4
While it is possible to use diesel fuel as a carrier for Garlon 4, it is not recommended to use diesel fuel in a pump sprayer. This is because diesel can ruin the spray motor seals and damage the pump, causing it to wear out faster.
Some people have used diesel fuel with Garlon 4 successfully, but they tend to use cheaper pump sprayers that can be thrown away afterward. One example is the Chapin 3.5-gallon concrete sprayer 1949. However, it is important to note that the manufacturers of sprayers cannot recommend their use with diesel fuel due to liability issues.
If you are looking for a cost-effective option to use with Garlon 4, diesel fuel may be a suitable choice. However, it is important to be careful and avoid damaging your equipment.
Garlon 4 Ultra Herbicide provides instructions for an oil-water mixture spray that includes diesel fuel. It is important to note that water or mixtures containing water should not be added to Garlon 4 Ultra, as this may create a difficult-to-break emulsion.
Before using any sprayer with diesel fuel, it is essential to check that it is diesel-compatible and can handle petroleum products.
