Matt Saunoras Posted January 18, 2014 Share Posted January 18, 2014 Anyone know the differences between 3C3Z-9A543-AARM and 4C3Z-9A543-AARM? Obviously one is for the straight rail 03 and the other fits the wavy rail 04. Possibly different pressure output? Quote Link to comment Share on other sites More sharing options...

Matt Saunoras Posted January 18, 2014 Author Share Posted January 18, 2014 HA I found that in the coffee table book. So what happens when you put an 04 pump into an 03? Quote Link to comment Share on other sites More sharing options...
Aaron Posted January 19, 2014 Share Posted January 19, 2014 Higher output at constant IPR You could sell it to some of the forum weenies as an upgraded 03 pump for 03 only - for an additional 600 bucks. Kind of like the "Spartan TCM" for the 2008 trucks. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted January 19, 2014 Author Share Posted January 19, 2014 Well I am going to have an answer for you guys because I just "fixed" an 03 no-start with an 04 high pressure pump. Long story short I diaged a truck for a towing company in their garage after hours. 03 no start, sawtooth ICP. Owner says wait there's a high pressure pump around here somewhere, let me find it. I said, yeah smallish box, should have a 3C3Z part number. He says okay btw if you want the job it's yours. After some digging around we find a pump, pull it out, everything is there. I'm in autopilot so I throw it in. Truck starts right up, running like a top. Shut it down. Gather up my shit to leave for the night, grab the box to toss the core in and there it is, the label. 4C3Z-9A543-AARM I'm thinking you have got to be kidding me.
