Just out of curiousity, how do you know yours is on its way out?

check it at the dealer my buddy works at. he let me borrow the scanner and the rail pressures are between 12,000 and 15,000 psi at full throttle. it is on it's way out like i said. not out but almost.

Was that driving it on the road with a load on it or just revving it in the shop? Trying to figure out how to check mine. Thanks.

I assume that is with your TST turned up some, if so you may find you need a pump upgrade not just a replacement. Even a new stock unit may just not keep up with all the fuel your engine is requesting. I know there are a couple companies that are moding the CP3s I just can't remember who they are off the top of my head.

One other thing to remember if you had a pressure box on your truck like the EZ, the readings shown on your obd-2 scanner won't be accurate. They will read lower then actual.

This is from http://www.relentlessdiesel.com/

We've finished with design and performance testing of stage 1 pump mods.

It dyno'd an increase of 86 HP over the stock CP3. This was done in a truck that had two boxes, a set of custom Relentless Diesel Injectors and a FASS fuel system.

We are now doing durability testing on that product.
That kit will sell for $1495.


We are currently working on our stage 2 pump mods and will have more solid numbers in a few weeks. Performance gains should be 30-50 HP more than Stage 1. Additional cost will be under $1000.

We'll be doing a more formal product release mid to late January '06.
