Replace your rusted out coolant bypass tube with this stainless option from PPE. This upgraded tube is specifically designed for use with the factory water pump. TIG welded 304 stainless steel construction looks great and prevents corrosion. 

If your encountering fitment issues with upgraded pump housings or replacement coolant tubes, this is the solution. PPE's tube provides additional clearance where it counts. We recommend these tubes when installing our high performance LB7/LLY water pump. 

Comes with O-Rings
