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.

Size: 25-Foot, Style: Expandable Fabric
This hose easily kinks, which restricts the flow. But it is easy to manage the kinks, you just need to be aware of them. It is easy to handle and store. Great quality. I will buy this hose again.

Very compact
Size: 50-Foot, Style: Expandable Fabric
The hose is flat, so it doesn’t take up much room, which is great. However, being flat, it’s way more challenging to roll it up, but overall still a really good hose.

Leaked after 2nd Use
Size: 50-Foot, Style: Expandable Fabric
It leaks. I read many reviews and finally decided on this Camco EvoFlex water hose to use with our new travel trailer. I loved that it was flat, light, and flexible. On our 2nd campng trip it started leaking. The water was seeping through the hose near the connection to the faucet. (it was not dripping from the faucet connection) There must be small holes in the hose. We did not notice it at first because it was so slow, but after a few hours we checked on our hook ups and we noticed water puddling and dripping down the hose. Luckly we had a back up that was not this brand that we switched to. We tried it again the next day hoping we had just set it up wrong, but it continued to leak water through the hose. I was disappoinnted because this hose was what I was initially looking for.

Awesome Hose for the Price and the Perfect length
Style: -20-Degree, Size: 12 Feet
We loved this product and was so great over the winter. It is so think and does not freeze over the winter. Temp was 0 and below and it had no issues. The length is perfect for a camper hookup and you are not always tripping or having a bunch of hoses laying around. It was so easy to use and install. The hose is stiff so it does not kink but is easy to move around. It is very thick so it has held up well.
