Removal fuel lines and hoses (Renault 19)

From the fuel level sensor in the tank, the fuel line goes through the fuel filter to the engine. The fuel lines leading to individual elements of the fuel system are made of particularly durable material, as they must withstand high operating pressure, which is 3 bar. The connection points of the fuel lines are additionally equipped with clamping or threaded clamps.

Cleanliness is a must when working on the fuel system. When working, make sure that no dirt gets into the removed pipes and hoses.

1. To loosen the clamps, flatten the metal loop with pliers. This will stretch the clamp and allow the hose to be removed using a twisting motion.

2. Using a thin screwdriver inserted into the loop of the clamp, stretch and loosen it by turning the screwdriver right and left.

3. Remove the hose by turning it from side to side.

4. If this does not work, squeeze the hose using a wrench.

5. When reconnecting hoses, install threaded clamps instead of clamps.

6. Threaded clamps are reusable. When tightening, do not apply too much force, otherwise the threaded connection will be torn off and the clamp will be broken. In addition, a clamp that is too tight can squeeze the hose.

7. Do not overtighten the pipe connections that are tightened with hollow screws. Before doing this, check the degree of wear of the sealing rings and replace them if necessary.

8. Remember that the fuel system remains 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.
