8mm 5/16" rubber multi-purpose fuel hose pipe tube is a flexible hose used for transferring various types of fuels from one location to another. The inner diameter of this hose is 8mm, which is equivalent to 5/16 of an inch. This small diameter makes it suitable for use in tight spaces or for transferring small amounts of fuel.

The hose is made of rubber, which is chosen for its durability and resistance to heat, chemicals, and weathering. It is also reinforced with layers of fabric or steel wire to provide additional strength and support. The hose is flexible and can be easily bent or shaped to fit the needs of the application.

This type of fuel hose is commonly used in automotive and industrial applications, and can be connected to tanks, pumps, and other equipment using metal or plastic fittings at the ends of the hose. It is also resistant to UV damage, which makes it suitable for use in outdoor applications.
