Improve your LML Duramax's reliability and fueling capability with a CP3 conversion. Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms. Failures of the CP4 are extremely costly and require replacement of the entire fuel system. Our kit provides you with OEM fit-and-finish features like a brand new Bosch CP3 with heavy duty 10mm cam, Fleece exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and our valley feed line to support aftermarket lift pump applications. Features: Heavy Duty CP3 with 10mm displacement cam High flow CP3 feed and return fittings Preformed feed and return fuel lines Kit Contents: CP3 to rail high pressure fuel line High flow CP3 feed and return fuel fittings Preformed feed and return fuel lines CP3 mounting adapter Dosing injector fuel lines and mounting bracket FCA extension harness Low pressure fuel feed lines Hardware kit Application Notes: This kit has been tested for use in stock application trucks that did not utilize a fuel lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 2 psi. Engine surging may be induced by the additional fuel pressure of a lift pump operating at pressures over 2 psi. For higher lift pump pressures, FCA table values will require adjustment.

Fair quality all cotton Oxford with wide choice of colors
Size: Small, Color: Sky Blue
This is real oxford cloth with the warp dyed and weft left white. It's actually 100% cotton. I've ordered several other "100% Oxford" shirts on Amazon that were not. Amazon's own Essentials brand OCBD is better than this Cotton King brand and only half the price, but it is not offered in even a fourth of the colors. I like all the pastels. Amazon's "Stretch" version is not Oxford cloth or cotton at all. These Cotton King shirts are a bit lighter weight than the non-stretch cotton Amazon Oxford shirts which are about the same weight as the original Brook's Brothers or Lands' End "Sail Rigger Oxford" which is their current heavyweight oxford as well as their "Hyde Park" Oxford from the past. The Brooks Brother's USA-made Oxfords may be worth it, but I don't have a use for them. Their imported "Friday" Oxfords are just overpriced. Lands' End has been changing their sources and the fit is inconsistent often with sleeves that are too short and very few color choices. The all-cotton Amazon Oxfords are at least as good as the Lands' End and Brooks Brothers Friday shirts, sell for as little as Lands' End's lowest sale prices, and fit better, but the color choices are few. I've only bought these Cotton King in a few colors the others aren't offering. They're more expensive, but still half the price of the Friday shirts and worth just as much.
