Replacing The Air Purge And Fuel Filter - Husqvarna 545RXT AT Workshop Manual

10.5 Replacing the air purge and fuel
filter
The air purge facilitates the start of the engine when it is
cold. The fuel pump fills the carburettor with fuel before
the engine is started. The fuel pump also prevents
blockage of vapor bubbles in the narrow fuel channels.
If the pump does not work it must be replaced.
1. Remove the cover over the fuel pump.
2. Remove the fuel hose (A) from the connection on the
carburettor.
3. Clamp together the spring clip and pull off the fuel
hose (B) from the fuel pump.
4. Remove the screws (C) and lift off the fuel pump with
the suction hose and fuel filter attached.
See figure 5.
5. Use a small screwdriver and pry the fuel hose (D) off
of the fuel pump (E) to replace any damaged parts.
See figure 6.
6. The fuel filter (F) must be replaced with a new filter if
it is dirty. See figure 6.
7. Make sure that the filter is placed curved forward in
the fuel tank. See fig. 6 pos. G.
