AI Technical Summary
Technical Problem
Water intrusion into the intake port of an air filter case connected to a fuel supply inlet pipe during vehicle washing poses a risk, potentially damaging electrical components downstream.
Method used
A vertical wall extending circumferentially on the fuel supply inlet pipe between the intake port and fuel cap is designed with a height exceeding the distance from the pipe's outer surface to the air filter case, preventing water from entering the intake port.
Benefits of technology
Prevents water entry into the air intake, reducing exposure to electrical components and simplifying the structure without altering existing components.

Abstract
It prevents water from entering the air intake. [Solution] The fuel inlet pipe 10 is provided with a vertical wall 30 extending in the circumferential direction on the outer surface of the fuel inlet pipe 10, between the intake port 22 of the air filter case 20 provided on the outer circumference of the fuel inlet pipe 10 and the fuel cap 40 that closes the opening 11 of the fuel inlet pipe 10. The height of the vertical wall 30 in the radial direction of the fuel inlet pipe 10 is made longer than the length from the outer surface of the fuel inlet pipe 10 to the outer surface of the air filter case 20 at the intake port 22.
