Fuel-supply line

On injector engines hoses and pipelines have to resist to pressure more than in 5 bars. Hoses are made therefore of the special material possessing the high resistance to pressure, and in junctions they are screwed together one with another or connected by collars.

Removal of toplivoprovodny hoses and tubes


  1. Purity – the first precept during the work with fuel system. Before work you have to clear at least that place in which will work in order that dirt did not get to an open fuel-supply line.
  2. Removal of collars: nippers to squeeze metal loops. Because of it the buckle will extend then the hose of the pipeline can be removed rotary motions.
  3. If it is impossible, for the end of a hose to establish a small rozhkovy key and to wring out a collar to them.
  4. At installation you have to apply bolted connections instead of coupling collars.
  5. During the work with models with the 5-cylinder engine and system of injection of KE-III-Jetronic it must be kept in mind that the fuel system is under pressure even later long time after shutdown of the engine.
  6. At removal of a fuel-supply line keep in readiness a rag that fuel incidentally did not scatter to you in eyes.
