Fuel Line
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 791766

This is a fuel line replacement intended to keep a lawnmower's engine running smoothly. It is long enough to make a couple of fuel lines, just cut the fuel line to the desired length and keep the rest as a spare. When a mower doesn't start easily or performs poorly when running, the fuel delivery system may have a problem and will need repair. The fuel line that supplies gas from the tank to the carburetor may be cracked or broken. When this occurs, it is best to replace the fuel line before it becomes a flammable hazard. This is an OEM replacement fuel line sourced from the manufacturer and is sold individually. This replacement part is compatible with different Briggs & Stratton mowers. Remember to use work gloves and drain the gas tank before the installation of this part.
