The fuel tank is a key component of the fuel system. Its job is to safely store diesel fuel and protect it from contamination. If your tank is cracked and leaking, has leaking connections, or is heavily contaminated inside with sediment that cannot be removed, it is time for a replacement. Continuing to operate with a damaged tank not only risks fuel loss but, most importantly, contamination of the injection system, leading to costly failure of the pump and injectors.
If the old tank was contaminated, the fuel lines must be flushed before installing the new one to prevent dirt from reaching the new pump.
The fuel level sender and suction strainer must be transferred from the old tank. This is a perfect opportunity to inspect them and, if necessary, replace them with new ones.
After replacing the tank, you must install a new set of fuel filters (e.g., from the REDX brand) to ensure the entire system is clean.
Ensure that the supply and return lines are correctly connected and that the hose clamps are tight to prevent air from entering the system.
Answer: Yes, if it is heavily contaminated and the dirt is blocking the suction strainer. This restricts fuel flow to the pump, causing a loss of power, especially under load.
Question: Can I weld a cracked plastic tank?Answer: It is highly not recommended and dangerous. Repairing a cracked fuel tank is very difficult, not durable, and risks leaking again. A replacement is the only safe and reliable solution.
Question: What is the main cause of tank cracking?Answer: The most common causes are mechanical damage (impacts) and material fatigue from constant vibrations, especially if the tank mountings are loose or damaged.
