How To Replace Fuel Lines On Leaf Blower
Article and Pictures by Mark Trotta
What began as a simple "drain the old fuel and refill" turned into yet another project. As the old fuel mixture poured out, so did broken pieces of the old fuel line!
Replacing the fuel lines on this Poulan leaf blower started with taking off the carburetor. After the carb was removed, the plastic gas tank came off with two mounting bolts.
There are two fuel hoses that run from the carburetor to the gas tank. The longer, thicker one has a filter on the end of it and pulls the gas/oil mixture in. The shorter, thinner line comes from the primer bulb, and returns excess gas/oil back to the tank.
Fuel Line Replacement
On the top of the gas jug, there are two small holes which the fuel lines go through. The longer gas line is 3/16" ID and shorter gas line is 3/32" ID.
To help get the hose through the tight opening, carefully cut the end of the hose at a 45-degree angle with a sharp razor blade.
The angled end helps put it through the small holes.
Once the hose is about a half-inch into the jug, grab it and pull it through with a pair of needle-nose pliers.
Since the blower is usually held at a slight angle downward, you want the fuel filter to sit near the lowest part of the tank.
While re-installing the fuel lines to the carburetor, it helps to lay the blower on it's side.
I no longer use Ethanol-blended gas in any of my lawn equipment. Look for non-Ethanol gasoline in your area. Also consider canned gas, which is convenient, but more expensive than pump gas.
The Poulan BVM200VS leaf blower requires a 40:1 gas/oil mix, which is 3.2 ounces of oil per one gallon of gas. Not all two-stroke engines take the same fuel/oil mixture. Check that you are using the right ratio for yours.
