BBI Injector Supply Tubes: 2003-2007 5.9 Cummins


Why you need new supply tubes:

It is always a good idea to install new supply tubes when you install new BBI injectors. The supply tubes have an edge filter inside which breaks up all particles bigger than 50µm into smaller pieces to avoid heavy injector failures.

Your old tube edge filters likely have worn edges causing particles over 50µm to get into the injector. Also the sealing cone on the tip of the supply tube can show some wear over multiple assembling processes; Leading to leakage between the injector and the supply tube so it is always worth it to add supply tubes to your injector purchase

Overnight shipping charges vary, if the cost is higher than the estimated flat fee you will be contacted for authorization to charge the difference.
