If you're experiencing issues with your fuel tanks not equalizing, you're not alone. This is a common problem, especially among truck drivers, with various potential causes. One possible reason is an obstruction in the tank vent, which could be caused by debris, a broken fuel cap chain, or even a plastic bag. Another cause could be an issue with the valves, which may not have the same flow rate or be fully open. Additionally, the crossover could be undersized or plugged, and fuel additives or partially ripped tinfoil could also be factors. Resolving the issue may involve checking and clearing the vents, ensuring valves are open and functioning correctly, and addressing any potential obstructions.

What You'll Learn
The crossover could be plugged or undersized
If your fuel tanks are not equalizing, one possible reason could be that the crossover is plugged or undersized. The crossover tube allows fuel to flow between the two tanks and maintains equal fuel levels on both sides of the aircraft. If this tube becomes obstructed or restricted, it can You may want to see also If your fuel tanks are not equalizing, there could be several reasons, including blocked return lines, air leaks, or faulty valves. In this case, the issue could be attributed to the valves not having the same flow rate or not being fully open. Cross-over valves, which regulate the flow between tanks, may stick or fail due to wear and tear. This can result in a restricted flow rate. To test if this is the issue, manually open and close the valves to check for smooth operation. If they are sticking, lubrication can help. However, if they are severely worn, the valves must be replaced to maintain proper fuel equalization. Additionally, the selector valve, which switches fuel flow between tanks, may be unresponsive or not fully open. To test this valve, manually switch it between tanks while observing the flow. If it is not functioning correctly, cleaning it may restore its functionality, but replacement may be necessary for long-term reliability. It is also important to inspect the fuel lines for any blockages or restrictions that could be impacting the flow rate. This includes checking for debris, sludge, or contaminants that may have accumulated over time, especially if low-quality fuel has been used. By addressing these potential issues, you can ensure that your valves are functioning optimally and that your fuel tanks have the opportunity to equalize. You may want to see also If your fuel tanks are not equalizing, one of the possible causes is a problem with the vent tubes or restrictions in the vent line. The vent tubes are located on top of the fuel tank. They should be checked to ensure they are clean and clear of any debris, such as bugs or dirt, which can cause blockages. To address this, some people suggest removing the vent tubes and cleaning them with a suitable cleaner, such as WD-40, and then blowing air through them to clear any blockages. It is also recommended to check for any obstructions in the tank vents, as these can cause issues with fuel tank equalization. In some cases, the problem may be related to the fuel return line being restricted. This can cause an imbalance in fuel levels, with one tank receiving the majority of the fuel. To diagnose this issue, it is recommended to pull the return line loose at all connections and check for any restrictions. If a restriction is found, it may be necessary to clear or replace the affected component. Another potential issue could be an obstruction in the supply or return lines from each tank. This can cause an imbalance in the fuel levels as the flow rate is affected. To address this, it is recommended to check the lines for any obstructions and ensure that the valves are functioning correctly and have the same flow rate. Additionally, it is worth noting that fuel additives, such as partially torn tinfoil, or rubber from a fuel nozzle, can also cause blockages in the fuel lines and contribute to the issue of fuel tanks not equalizing. You may want to see also If a chain on your fuel cap has broken off and fallen into the tank, it is essential to address the issue promptly. While some suggest that leaving the chain in the tank may not cause immediate harm, it is important to take preventive measures to avoid potential complications. Firstly, it is crucial to prevent fuel contamination. Ensure that the fuel cap is secure and tightly closed to avoid any contaminants from entering the tank, which could lead to issues with your vehicle's performance. To remove the broken chain from the tank, you can try using a magnet or a tool with grabber fingers. A telescoping magnetic stick or a long magnet can help retrieve the chain, especially if it is made of a magnetic material. If the chain is still attached to the filler neck, you may be able to fish it out. If the chain is detached from the cap and fallen inside the fuel hose or other fuel components, you may need to consider disassembling those parts for repair. In some cases, welding or using a product like JB Weld might be an option to reattach the chain. However, if you are uncomfortable with performing these tasks yourself, it is advisable to seek professional assistance. Additionally, it is important to inspect the fuel tank vents for any blockages. Blocked vents can cause issues with fuel equalization and should be cleared to ensure optimal fuel flow and tank performance. You may want to see also Debris in the tank can include a variety of materials, such as a gatorade bottle wrapper, the seal off a jug of fuel additive, a baggie, or a chain from the fuel cap. These objects can partially or completely plug the tank or the crossover shut-off, restricting fuel flow and causing an imbalance between the tanks. To resolve this issue, it is necessary to inspect the fuel lines and cross-over lines for blockages and remove any debris or contaminants. This can be done through a thorough visual inspection or by using a compressed air system to clear blockages, being careful not to damage the lines. In some cases, it may be necessary to replace severely damaged or blocked lines. Additionally, it is important to ensure that the tank vent is unobstructed, as a restriction in the vent can also contribute to fuel tank equalization issues. Regularly inspecting and cleaning the vents can help prevent blockages and ensure proper fuel tank equalization. You may want to see also There could be a few reasons for this. One common issue is vent problems. Another could be a restriction in the line. It might also be that the valves are not the same flow rate or are not fully open. You can try "burping" the tanks by removing the caps for a while and allowing the remaining fuel to equalize. You should also check the vent tubes on the top of the tank for any debris, such as bugs. It could be that the crossover is undersized or plugged. It might also be worth checking the chain on your fuel cap to ensure it has not broken off and fallen into the tank, which could also cause the issue.Bunded Fuel Tanks: What's the Meaning and Benefits?
