What consequence might occur from insufficient clearance in standard drop tubes?

Insufficient clearance in standard drop tubes can lead to an increased risk of leaks. When drop tubes are incorrectly installed or positioned too close to other components or the tank itself, it can result in improper sealing or pressure issues. This may cause fuel or other fluids to escape, which not only poses environmental hazards but can also create safety risks. Adequate clearance is essential to ensure that the drop tubes function correctly and that any potential fluctuations or movements do not compromise their integrity. Ensuring sufficient space during installation minimizes the chance of wear and tear on the tubes and seals, ultimately helping to prevent leaks over time.
