Fill pipe repair collar and method of use

摘要

A device and method of use for the repair of a leaking fuel tank fill pipe are provided. The device and method of use are designed to create a durable repair of a leaking tank fill pipe without the cost, time, and difficulty associated with replacing an entire diesel fuel tank on a semi-truck tractor. The device is a collar which threads onto damaged threads on a fill pipe neck and creates a leak-resistant seal with the fill pipe neck. A tank fill cap can then be screwed onto the collar, which forms a leak-resistant seal with the fill cap. The device may have one or more mechanisms to retain the collar on the tank fill pipe neck. The method of use may include re-cutting damaged threads on the fill pipe neck with the collar device.
