Einleitung
This guide is to replace all the fuel lines, grommet, fuel filter, ventilator, purge bulb and gas cap vent gasket. All of these parts come in a Echo Fuel Line Repower Kit. This repair is necessary when there is cracking in the purge valve, the fuel tank grommet is leaking, or the purge bulb is pulling excess air or no fuel when depressed. The ethanol that exists in fuel will eventually cause this repair to be necessary at least once during the lifetime of the trimmer. The ethanol will crack the fuel lines and purge bulb, as well as causing the fuel tank grommet to expand and become improperly sealed. No special skills are required for this repair and should be very straightforward. This repair is also applicable to many models of Echo trimmers and leaf blowers.
NOTE: ethanol-free fuel is available at most hardware stores in pre-mixed cans and will prolong the life of the fuel system components

After lines are disconnected, pry grommet from the gas tank. This can be done with a flat head screwdriver as shown or a pair of pliers.

It is going to be a tight fight so be sure to oil or grease the perimeter of the grommet to ease installation
-
Insert the fuel filter through small hole in the gas tank.
-
Use fingers to reset grommet into the fuel tank. It can be tough but it will squeeze in with enough effort.
