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.

All 3 dogs, 3 different sizes and ages love it! Can’t go wrong!
Size: Medium, Style: Bristle Bone
Great! Super great! When you HAVE TO GET THEM OUT OF YOUR HAIR! This toy is durable even without the beef flavored insert! I have a Border Collie who has too much energy and an Aussie who can’t sit still and a small stray who is constantly figuring out a way to steal these from the other two! Safe, effective and actually cleans their teeth! This might well be my first Amazon review because this toy deserves it!

Bully approved
If he wants something to gnaw on he will sit with it but he doesn't really play with it. Which is probably the point. It's lasted. The ends are the most chewed. Overall great for a chewer!

Surprisingly Durable
Color: Green
Our dog is an aggressive chewer. She has destroyed other toys meant for "aggressive chewers" in less that 6 hours. This toy has lasted 17 days and it's still going. It does have areas were the seam has given way and a very small amount of stuffing has come out. She has "killed" the squeaker. But the toy is still usable. We just played Tug of War this morning. It will not last forever. It is showing it's "age". But the durability is there. I am ordering more.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.
