The 15-19 pump interchanges with earlier 2011-2014 MY vehicles and displaces 15% more than the stock pump. Great for your hot tuned 11-14 truck to ensure proper rail pressure. PATENT PENDING The CP4 pump Bosch should have built, the CPX. • Pinned lifter buckets to prevent rotation and stop failures. Even during a gel. • New feed port, preventing any contaminated crankcase debris from entering the plungers and barrels. (Built in disaster prevention kit) • Direct drop-in replacement, no aftermarket fuel lines or components needed. • No additional labor or modifications to install. • 24 Month no questions asked replacement warranty. Three variations: 11-23 applications with the updated 15-19 pump output. (7.5mm) 10% over for hot tuned trucks (8.25mm) And the infamous 10.3mm 38% over pump. This CPX keeps the OEM, four pumps per engine revolution that the Chinese eccentric pumps do not. The OEM Bosch system is timed, and designed to pump to the bank that is requesting fuel (firing). This is to ensure peak nozzle pressure and less harmonics of high pressure fuel, having to cross over via the balance tube, from one rail to the other. Eccentric pumps will skip every other firing event. Two pumps per revolution vs the OEM four.. And just to point out, the whole “US diesel fuel doesn’t have enough lubricity for the CP4.” That’s a lie. I have disassembled, measured and under microscope, inspected pumps with over 500k miles with essentially zero wear. The flaw was nothing to stop the roller lifter from rotating in a vacuum event. (Gel, filter change, low pressure feed issue.) This is why the LML Duramax pumps drop like flies. There is no lift pump to keep positive pressure on the plungers and barrels. This allows a slop, or gap between the cam and the lifter roller. Which allows it to turn. Similar to a roller cam in a engine. When there is no lifter guide or link bar. The lifter rotates, destroying the cam and lifters and filling the engine with hardened metal filings. These filings, are what fills your fuel rails and injectors with debris, ruining them. All 2011 - 2023 RCD CPX CP4 pumps are modified internally in a 5 AXIS CNC to return fuel to the tank. This prevents debris from entering the injector in the instance of a failure. "DISASTER KITS" ARE NOT NEEDED!

Failure to do so can result in forfeiture of the entire core charge return • All cores must be returned to original warehouse that original shipment was sent from. In most cases, we do not provide return shipping labels for cores, if a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to. DO NOT rely on the return address on the original label as a source for where to ship to • If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount • Cores that have been disassembled or have missing and/or damaged major components will not receive full core credit • Cores must be returned in the original packaging the new part was shipped in. Most manufacturers design special packaging for their products to protect them while in transit. Failure to reuse this packaging can result in damage to the core(s) which could lead to the forfeiture of your core return. Specifically regarding Bosch, they have a strict policy that core returns must be in their original packaging. If the original packaging is not used, the part number must be clearly identifiable on the part itself. If neither of these core criteria are met, no core return will be available. • Returned cores must match the same vehicle fitment as the new part purchased. For instance, if you purchase a replacement turbo for a 2007.5-2012 Dodge Ram 6.7L Cummins, the returned core must have a fitment of that same application. • We have the right to alter this policy (i.e. extend the terms) for any reason.
