Blocked Tank Breathers/Drains

In this short video we look at and deal with a blocked tank breather/drain and use a simple but effective way of dealing with it.

On this occasion it was completely blocked in one side and required the use of a small drill bit and battery operated drill.

If left unattended, it can cause water to sit in the pipes and then overflow back up into the tank filler hole and drip into the tank and fuel. And as we know, fuel and water don't mix which can then lead to engine running problems.
