Why can't fuel be added to the fuel tank?

It may be due to hot weather causing increased internal pressure in the fuel tank, which leads to fuel splashing out during refueling, triggering the fuel pump nozzle to shut off. Alternatively, fast refueling speed can cause fuel splashing and nozzle shut-off, or the complex structural design of the fuel tank's piping system may result in fuel splashing and nozzle shut-off. There are three key points to note when installing a fuel tank: 1. Storage location: The fuel tank must be placed in a safe location to prevent fire hazards. The tank or fuel barrel should be stored separately in a visible area, at an appropriate distance from the diesel generator set, with a strict no-smoking policy enforced. 2. After placement: The highest fuel level must not exceed 2.5 meters above the base of the diesel generator set. If the fuel level in a large fuel depot exceeds 2.5 meters, a daily fuel tank should be installed between the depot and the generator set to ensure the direct fuel delivery pressure does not exceed 2.5 meters. Even when the diesel generator set is turned off, fuel must not be allowed to flow into the diesel engine by gravity through the fuel inlet or injection lines. 3. Resistance requirements: The resistance at the fuel port must not exceed the specified value for all diesel generators. This resistance value is based on the fuel tank being half full.
I have encountered the situation where the fuel tank cannot be filled several times. The most common issue is the fuel cap getting stuck and not opening fully, and sometimes the cap ages and deforms, requiring replacement. Additionally, the fuel filler inlet may be blocked by dust or leaves, which needs to be cleaned thoroughly. If the exhaust system is not functioning properly, fuel may flow back out because the fuel tank needs to vent during refueling to prevent overflow. There is also the possibility of the anti-rollover safety valve getting stuck, which is originally designed to prevent leaks during accidents but now obstructs fuel intake. During inspection, first ensure the cap opens and closes smoothly, clean any debris from the inlet, and try adjusting the angle of the fuel nozzle to avoid forcing it in and damaging the tank. It is recommended to regularly clean the fuel filler inlet and inspect the cap's sealing strip to reduce the frequency of such issues. Addressing small problems promptly ensures smooth driving at critical moments, avoids delays in travel plans, and minimizes disruptions.
