From the fuel level sensor in the tank, the fuel line goes through the fuel filter to the engine. The fuel lines leading to the individual elements of the fuel system are made of particularly durable material, as they must withstand a high operating pressure of 3 bar. The fuel line connections are additionally equipped with clamping or threaded clamps.
Cleanliness is a prerequisite when working with the power system. When carrying out work, make sure that dirt does not get into the removed pipelines and hoses.
1. Flatten the metal loop with pliers to loosen the clamping collars. In this case, the clamp is stretched and the hose can be removed using rotational movements.
2. Using a thin screwdriver inserted into the loop of the clamp, stretch and loosen it by turning the screwdriver to the right and left.
3. Turn the hose from side to side to remove it.
4. If this fails, wring out the hose with a wrench.
5. When reconnecting hoses, install threaded clamps instead of clamping clamps.
6. Threaded clamps are reusable. When tightening, do not apply too much force, otherwise the threaded connection will break and the clamp will be broken. In addition, a clamp that is too tight can pinch the hose.
7. Do not overtighten pipe connections that are screwed in with hollow screws. Before doing this, check the degree of wear of the sealing rings and replace if necessary.
8. Remember that the fuel system is under pressure for a long time after the engine is turned off.
9. When removing the fuel line or hose, use a rag to avoid getting fuel in your eyes.
