Another premium bolt-in lift pump option for your 6.5L turbo diesel!

Great for low ground clearance installations, or applications where larger integrated pump/filter kits will not fit without hanging below the frame.  Accomplish the same task in a more compact, distributed package and support the fuel requirements of all 6.5L applications. 

 Georotor design with one moving part and no vanes to wear delivers quiet operation, and dependable fuel delivery.
