What are the effects of removing the fuel tank on a car?

Removing the fuel tank will not have any impact as long as it is properly reinstalled. Below are some relevant details about the fuel tank: 1. It is a container for fuel in a car and a specialized vessel in the hydraulic system for storing hydraulic oil or fluid; 2. The fuel tank must have sufficient capacity, with the suction and return pipes inserted below the minimum liquid level to prevent air suction and splashing of return oil that can create bubbles. The distance between the suction and return pipes should be as far apart as possible, with a partition installed between them; 3. To maintain oil cleanliness, the fuel tank should have a sealed cover around its perimeter, equipped with an air filter. The bottom of the fuel tank should be at least 150mm above the ground. Adequate attention should be paid to the anti-corrosion treatment of the inner surface of the fuel tank.

Last time I removed the fuel tank for car modification, I realized how risky it was. The fuel tank isn't just an oil storage container; it's connected to the entire fuel system, including the pump, pipelines, and filter. After removal, if not properly sealed or reinstalled, the risk of fuel leakage is extremely high. This doesn't just cause engine stalling or difficulty starting, but may also lead to fires. Especially in modern cars, emission control components like the carbon canister can be affected - dashboard warning lights are the least concern, long-term issues include environmental pollution or even violating emission standards. What worries me most is safety: gasoline vapors meeting sparks can cause explosions. So unless it's professional racing modification for weight reduction, ordinary car owners should never attempt this - it's best handled at a repair shop.

Years of driving experience have taught me that tampering with the fuel tank is asking for trouble. It's connected to the engine's fuel supply system, and removing the tank can cause the fuel pump to run dry and burn out. A disrupted fuel line means the engine won't start or will shake like a tractor. Evaporating residual gasoline can leave an unpleasant odor inside and outside the car, even attracting rust that damages the undercarriage. I've seen cases where improper reinstallation after removal led to leaks, staining the garage and requiring lengthy repairs. The fuel tank is designed as part of the vehicle's balance; removing it alters weight distribution and affects cornering stability. For routine maintenance, it's best to visit an auto repair shop—they can handle fuel line replacements properly and avoid these risks.

As a modification enthusiast, removing the fuel tank can indeed enhance performance, shedding dozens of pounds for a more exhilarating acceleration. However, it must be handled professionally: either reconnect the fuel lines properly or install a temporary fuel reservoir, otherwise, the fuel pump running dry could get damaged. The risk of fuel leakage is high, with gasoline fumes filling the car, which is unsafe and pollutes the air. After modification, thorough testing of the sealing and fuel supply smoothness is essential. In fact, the fuel tank is connected to the emission system, and tampering with it improperly might trigger the warning light, affecting the annual inspection. When I modify, I always proceed with caution, ensuring everything is secure before hitting the road.
