***IMPORTANT NOTES**
-The center nut for the replacement hub should be torqued to 60nm OR 44 ft/lbs,
– The custom threaded adapter is torqued to 60 ft/lbs.
–TRANSFER OVER THE SPRING FROM THE OEM FITTING TO THE NEW FITTING; otherwise your pump will fail very, very fast.
-Factory rail pressure sensor is 1875 BAR. When it fails, it’s very expensive to replace, so some customers like switching to the 2200 bar sensor as it’s much more economical. It’s only required for above 200 hp builds. If your factory sensor is working correctly, do not try to do this preemptively, as you will likely create more problems than you will solve.
-If you have ANY debris in your fuel system, it will clog the internal screen on the HPFP. Often this will blow out the plug and cause a fuel leak. Bosch has made it clear that this is not an issue with the pump but rather not enough prep being done, so make sure your fuel system is completely clean to avoid buying two (or more) HPFP’s! As of this writing, the only CP3 failures we have seen have been due to debris in the system. The pumps are extremely reliable, and we have had 0 failures/warranty claims for actual pump defects.
-If you are not getting fuel to the injectors, but your aux pump is running, make sure you don’t have the fuel filter lines reversed!
-This kit does not require tuning unless you are currently tuned. In that case, you will likely need a tune update. See above for metering valve part numbers. You are still responsible for confirming the part number you receive with your kit and coordinating with your tuner.
-Some customers have chased fuel rail pressure codes. If your rail pressure code is too high, it’s likely a software issue and will need a tune update. If it’s too low, it’s usually mechanical in nature – injector or fuel rail.
-2015 CRUA/CVCA Customers only: You will have to do a lot of bending on one of the fuel lines. We are working to come up with a custom solution; however, getting a custom line built that can handle 35,000 PSI is not an easy task, so for the time being you will have to make do with bending. With over 100 kits sold to 2015 customers as of this writing and climbing, this does work. Our updated steel gears and brackets reduce the need to clearance the bottom mounting bracket below the pump. However, some clearancing will still be required.
-We will update this list with any other patterns we find. If you have any helpful hints, please email them over, and we will update the listing as needed. Please note one-off experiences may not make the list, but as patterns emerge, they will make it up here.
