Looks like if your an owner in select states, you can get a claim award. These CP4 pumps were notorious for failure due to improper specs for low Sulphur diesel and if they grenade, it would take out the entire fuel system including tank, filter, pump, rails, lines and injectors. Was costing $10-12k for a fix.
I ran a lift pump and lubrication for mine and so far it's still running fine for my boy after 11 years.
GM could have bought a lot of pumps for $35 million, but they never admit their faults until lawyers collect their millions!
2500 HD ZR2 uses an entirely different pump, including a lift pump.
