Cp4

Hey guys. I’m on the 6.5 side. My dad just bought a 2013 lml. Are you guys converting over to cp3 pumps. How many miles are the cp4 lasting? Thanks

CP4 could last a few thousand mile and there’s some that have over 400,000 miles and still running fine.
Might be something in one of these.

Most conversion kits are around $1800 than Labor is about the same. So your talking about $4000

Google “duramax LML How many miles are the cp4 lasting”

My 2013 had catastrophic injection pump failure at 52,000 miles. Pump filled whole fuel system full of metal shavings. Luckily, warranty covered the bill. This will be my last Duramax. Of course, everyone but Cummins uses the CP4. There was a lawsuit filed in Texas this month on the CP4 failures.

The L5P doesn't use the CP4.

Good to know. This will most likely be my last diesel regardless.

Could there be a way to put some kind of device (filter etc.) post pump to contain all the debris?

While it's not absolute, it is an improvement.

Quote:
The System Saver Inlet Valve was designed to offer you the piece of mind in the event of a CP4 Pump failure. The important difference between the OEM valve and the System Saver is the improvement made to the screen, which is upstream of the valve inlet. The OEM screen is a single 80 micron layer, and is a very flimsy design. In extreme cases the factory screen can actually tear, introducing massive amounts of debris (from the failed pump) to the injectors. The System Saver Valve screen is rated at 25 microns and is wrapped in two layers. This improved micron rating and double wrap construction will do a much better job of keeping debris from entering the rest of the fuel system. It is also constructed in a (manner) where it will not be able to tear or de-laminate from the filter housing. Another benefit to the screen is the fact that it will load up quicker than the factory screen in the event of a pump failure. This will choke off the valve sooner, which will bring the truck out of service and shut it down in a shorter amount of time.
