  • Avoid breaking glow plugs & causing more costly repairs
  • Checks compression via the injector bore
  • Held in place with the truck's own injector hold down clamp
  • Threaded to accept a common 1/8" NPT compression gauge

This tool was conceptualized by one of our own technicians. The common practice of checking compression through the glow plug port can create problems. Glow plugs don't always like to come out of the engine very well and have been known to break off causing much more extensive and expensive repairs - up to and including cylinder head removal. The 99-1079 tool was created to avoid that issue altogether! 

Instructions 

Thanks for having that fuel pump in stock for my 5.9L. Worked great.
