1.3.3.5.1. Fuel hoses
Precisely it is difficult to define fuel leak until leak becomes essential and, therefore, it is easily visible. Fuel tends to evaporate quickly as soon as it contacts with air, especially in a hot motor compartment. Small drops can disappear before you are able to define the place of leak. If you suspect that there is a leak of fuel in the field of a motor compartment, then cool the engine and start it, it cold at an open cowl so far. Metalli chesky elements tend to contract in a cold state, and rubber hoses tend to be weakened so any leaks will be more obvious while the engine heats up from start from a cold state.
Carefully check all rubber hoses and metal fuel-supply lines departing from the fuel tank. Check the weakened connections, worn-out hoses, the twirled fuel-supply lines and other damages. Pay special attention to pipes of ventilation and hoses which often resteep slopes are howled around a hose of a jellied mouth and can be blocked, doing a tank difficult filled. Follow fuel feeding and returnable hoses to a forward part of the car, carefully examining them completely on signs of damages or corrosion.
