Chainsaw fuel lines are an essential component of the machine's engine, and occasionally they need to be replaced. There are several options available for purchase, including fuel line hoses made from PVC or petrol tubing. The process of replacing a fuel line can be challenging, and there are a variety of tools and techniques that can be used to feed the line through the holes in the fuel tank.

What You'll Learn
Using a hemostat to guide the line
Hemostats are a fantastic alternative to needle-nose pliers, which can be taped up to work on small engine fuel lines, but this can be a cumbersome process. It is recommended to get a pair of long-billed, curved hemostats for working on fuel lines, and a small set for your toolbox. You can also get a locking and a non-locking pair, which will be useful for a variety of tasks.
When working on the chainsaw fuel line, the hemostat can guide the line through the engine housing, and its curved shape can help to navigate tight bends and corners. The long, thin nose of the hemostat is perfect for this task, and its locking mechanism will ensure a tight grip on the line without slipping.
For those with older eyes, a cheap pair of reading glasses can be useful for close work, and a magnifier can also help guide the line through the housing.

Cutting the line to a sharp point
When replacing the fuel lines on a chainsaw, it is important to cut the end of the line to a sharp point. This is because a sharp point will fit through the hole in the fuel tank, and you can then grab the end with hemostats.
To achieve this, start by cutting the end of the fuel line at a sharp angle, creating a long, thin point. You want the point to be narrow enough to fit through the hole in the fuel tank. If you are struggling to get the line through the hole, you can try a few different techniques. One is to use a tool that often comes with small engine fuel line kits. This is a thin piece of wire attached to a key ring. Thread the wire through the hole, attach the line cut to a sharp point to the wire by poking it through, and then close the end of the wire tightly with some pliers.
Another technique is to cut the fuel line in half vertically and then pull the rest through with pliers. You may need to poke the uncut side with a screwdriver while pulling. If you have a genuine set of fuel lines that are cut to a specific length, you can try leaving them in boiling water to soften them before attempting to pull them through.
By following these steps and techniques, you should be able to successfully feed the fuel line through the hole in the fuel tank and secure it in place with the help of tools like hemostats or pliers.

Using boiling water to soften the line
Boiling water can be used to soften a chainsaw fuel line, making it easier to fit. This method is safer than using a heat gun, although it may not heat the line enough to make a difference.
To soften the line, boil some water and fill an unbreakable, insulated mug with it. Then, dip the hose ends in the hot water for a few minutes. This will soften the line and make it more pliable. It is important to act quickly, as the line will begin to harden again as soon as it starts to cool.
If the boiling water method does not work, you can try heating the brass fitting in boiling water and installing it while it is still warm. This can be more effective than heating the line itself, as the fitting will not suck the heat out of the plastic line, causing it to cool and shrink.
It is important to prioritize safety when working with fuel lines. Always ensure that the fuel tank is empty and that there are no sources of ignition nearby.

Pliers to pull the line through
Pliers are an essential tool when it comes to pulling fuel lines through on a chainsaw. The most commonly recommended type is needle-nose pliers, which are ideal for reaching into tight spaces and manipulating small parts. They can be used to remove the fuel lines from the carburetor and pull them out of the fuel tank. Bent needle-nose pliers are especially useful for grasping the tubing and pulling it through the tank.
To avoid damaging the fuel lines, some people suggest padding the jaws of the needle-nose pliers with strips of rubber or slipping short pieces of rubber tubing over the tips. This provides a secure grip without scratching or scraping the fuel lines. Others recommend cutting the fuel line in half vertically and then using the pliers to pull the rest of the line through. If the fuel line is particularly difficult to pull through, a small amount of lubricant can be sprayed onto the line to aid in its passage.
Hemostats are another tool that can be used in place of pliers for pulling fuel lines through. They are similar to needle-nose pliers in functionality but offer a different mechanism for grasping and manipulating objects. Hemostats are useful for reaching into tight spaces and can be employed to pull the fuel lines through the tank.
In addition to pliers, other tools such as scissors or snippers are necessary for cutting the fuel lines to the appropriate length. It is also important to wear protective gear, such as work gloves, to safeguard against potential hazards during the repair process.

Using a screwdriver to poke the uncut side
If you're struggling to get your fuel lines through the holes in the fuel tank, there are a few methods you can try. Firstly, ensure you have plenty of fuel line to work with. If the line is too short, it can be difficult to get it through the holes. One method is to cut the end of the line to a sharp, long point. This will make it easier to grab the line with a tool and feed it through the hole. You can use hemostats, which are specialised pliers, to grab the line and pull it through. If you don't have hemostats, you can try using needle-nose pliers instead.
Now, for the method that involves using a screwdriver: if you have a good amount of fuel line to spare, try cutting it in half vertically. Then, while pulling on the cut end, use a screwdriver to poke the uncut side. This will help to feed the line through the hole. It's important to be gentle and careful during this process to avoid damaging the fuel line.
If your fuel line is a genuine set that comes cut to a specific length, you might want to try a different approach. In this case, boiling the lines in water for a while can make them more pliable and easier to work with. This method can be useful if you don't want to cut the lines or if you don't have a spare line to work with.
Additionally, some fuel line kits come with a thin wire attached to a key ring. You can thread this wire through the hole in the tank, attach the fuel line to the wire, and then use pliers to pull the wire and line back through. This method can be useful if you're working in a tight space or if the fuel tank is in a difficult-to-reach location.
Remember, when working with fuel lines, it's important to take your time and be patient. It's always a good idea to have some spare line on hand, as it can be delicate and prone to damage during the installation process.
