Review on Ford 3C3Z-9T517-AG Fuel Pressure Regulator Kit for F-Super Duty 6.0 - All You Need to Know About 3C3Z9T517AG by Jeff Jackson

Revainrating 5 out of 5

Still working in my truck after 25,000 miles

Works great on my 2005 Ford f350 6.0l. Installed this kit a few months ago. Now the engine has driven about 40,000 km with this blue set of springs with "0" problems. Maintains my fuel pressure and doesn't feel any lag from loss of pressure. My truck always drives 15k plus kilometers negative. This is a great kit, exactly the same kit that Ford dealer will sell you with the same part numbers.

Pros
  • GOLS certified
Cons
  • Working speed
