I blew an injector line on a 20 yr old Cummins right at quitting time just as I pulled into Prince George. ... Ryder showed up first thing in the am pulled the line & took off to find a replacement. New lines were only 3 weeks out & the local parts places didn’t have the right lines. Soooo, the owner just happens to have the same engine in one of his trucks, tells Ryder to pull the line outta his truck n I’m back in business by lunch time!!! One word for this outfit, from the owner Jeff, Ryder, and the wonderful ladies in the office, WOW!!
