Description

2011-2016 LML CP3 Conversion Kit with PowerFlo 750Why convert your LML's Fuel System from a CP4 to a CP3? The stock CP4 is only capable of supporting up to ~500 RWHP. A CP3K is capable of supporting 600+ RWHP in conjunction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ RWHP. The CP4 was introduced as a cost reduction to the LML platform since a smaller amount of fuel is required when running the more efficient piezoelectric injectors.

Why convert your LML's Fuel System from a CP4 to a CP3?

  • The stock CP4 is only capable of supporting up to ~500 RWHP. A CP3K is capable of supporting 600+ RWHP in conjunction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ RWHP.
  • The CP4 was introduced as a cost reduction to the LML platform since a smaller amount of fuel is required when running the more efficient piezoelectric injectors. Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms.

  • High Pressure Fuel Rail Line
  • Fuel Rail Plug and Nut
  • CP3 Block Adapter with O-ring
  • (3) CP3 Block Adapter Bolts (Flange Head, M8x1.25x35mm)

Nice shirt but size up one to two sizes.
Size: Large, Color: Clay
I love this shirt. it is good quality. I got the clay colored one. I really like it. They do run small. I normally wear a medium. So I got a large. It fits pretty well. It is a tad bit tight, but I am losing weight(145LBS) So far. So it should fit fine in a few weeks. I am 5,2 135Lbs. I probably should have gotten the XL.

Slim fit for the winner
Size: Medium, Color: Clay Floral Print
Beautiful orange shirt and I love the metal buttons. Very comfortable and I like the slim fit. It appears more tailored. I'm a tall guy at 6'4" and the length for a medium was perfect.
