Question by: Scott T on Mar 19, 2026, 9:21 PM
got a tight turn coming off the tank. how sharp can i bend this 5/16 fuel hose without kinking it?
Answer by: Customer Support on Mar 21, 2026, 6:02 AM
For tight routing, the minimum bend radius on this hose is 2.5 inches. Staying at or above that bend radius helps it keep its shape and flow, especially with the 2 spiral polyester reinforcement.
