I have had two replacement CP3s. The factory one started leaking at one year. The second one began to seep fuel also at one year. The dealer was instructed not to replace for a mere seeping problem. It took another year to start leaking like crazy. It was replaced 12/15/05. They did not check or replace the lift pump. My truck is bone stock,no gages, nothing. DC needs to quit calling any of us owners liars and just fix an unmodified truck. Gages causing the pump to leak, come on DC!

 

I had an '04.5 4x4 dually that had a boost and egt gauge, as well as bed-mounted exhaust stacks. These things were done by the selling dealer, WHILE THE TRUCK WAS STILL NEW. I bought the truck brand new with that stuff already on it.

 

when I purchased my truck brand new from the dealership I asked to talk to the service manager to ask him a few questions. I met him right away and asked him "what can I do" he asked "what do you want to do" he was very helpful and answered me straight up. He encouraged me to install gauges, even to modify the exhaust, just NO PROGRAMMERS, and NO K&N AIR FILTERS. He said those two things together or combined would stop any warranty on the engine or possibly the driveline.
