Mikuni BST Fuel Piece Seals X2 - N198006

A tiny seal that can cause a big problem when it fails.

These Mikuni fuel T-piece seals sit around the fuel connections between carburettors. Over time, the original seals can harden, flatten and deteriorate, leading to fuel leaks between the carburettors.

Ideal to replace during a carburettor rebuild rather than putting everything back together with old seals and discovering a fuel leak afterwards.
