Technical characteristics


In our engines with fuel injection hoses and gasoline pipe lines should maintain pressure more than in the 5th bar. Therefore hoses are made of a material steady against pressure, and in junctions are in most cases screwed together or supplied with tightening collars.

Dismantle топливопроводов and fuel hoses


  1. Purity – the basic law at works on fuel system. You should clear previously at least of dirt that area where work will be made in order that dirt did not get in opened топливопроводы.
  2. Weakening of tightening collars: nippers flatten out a metal loop on its perimeter. At the expense of it tightening the collar extends, and the fuel hose can be removed rotary motions.
  3. If it is impossible, establish on the hose region a rozhkovy key and wring out them a hose.
  4. At installation you should use the screw instead of tightening collars.

     Important: the fuel system still long time after switching off of the engine can be under pressure.

  5. When unscrewing a gasoline pipe line keep in readiness a rag in order that to you gasoline did not scatter in eyes.
