New Injector Tube for 2003-2007 Dodge 5.9L Part # 1050

Bosch# F00RJ01572
Part# 3979419 – 4929864

Cummins & Bosch both recommend replacing these tubes everytime the injectors are replaced.
Leakage at the tube is a common problem… Which causes hard start and no-start symptoms.

Would you rather use Bosch made in China injector tubes… or these made in USA injector tubes?
