P7100 Number Identification

People refer to specific P7100 pumps by numbers like this:
160hp(838)
175hp(841)
180hp(885)
215hp(887)
and I have seen others, but these seem the most common.

Where do the #885 & #887 come from?

I can't find anything like this on either of my trucks' pumps. My pumps are both marked CPL 2174, and I understand that. I've found a pretty complete rundown of CPL numbers, and what CPL was used in what application.

:thankyou2:

Add 911(180 pump)
and 913(215 pump)
160 are auto 94-95
175 are manuals 94-95
885 and 911 are autos 96-98
887 and 913 are manuals 96-98

I'm not sure i understand your question. If you are asking where you find those numbers, they are on the left side of the pump behing the throttle bracket, right below the #2 DV. The id plate looks like this.

Thanks Dave! Knowing where to look is the whole secret. I can just see the edge of the plate behind the throttle position sensor & pivot plate. Can't read it until that stuff is out of the way.

Here's information on pump #s and CPLs I've collected to this point:

Bosch P7100 FI pump numbers Ram CPL #s (engine data plate)
--------------------------------------------------------------
215hp - 887 - 913 ................ 2023*> 2175
180hp - 885 - 911 ................ 2022*> 2174
180hp - 866 uncommon. ....... ??
160hp - ??? ........................1863*> 1968 - CA EGR & Auto
.......................................... .... *> revised to next CPL by TSB 11-18-96
160hp/175hp - 841 - 854 - 838 ... 1549, 1550, 1815, 1816, 1959 49 State.

I've got a 13mm pump that has the number 800 as the last three, I'm guessing they used just the case, it's an old PDR race pump.

i have two motors that have a flexplate (auto) on them with 887 pumps. never saw the truck they came out of. are you sure a 887 is only on a manual?

i thought a 887 and 911 was auto, 885 and 913 manuals.
 
I have an 847 pump, still trying to figure what it goes to ... Engine was battleship grey and sitting on the floor when I got it and don't know the source. I have been told CPL 1552 and CPL 1914 ???

What about a 938? My buddy who bought my 95 said that's what it has on it. CPL # is 1959, 160 hp auto.

They were going to time it today, and said the plunger lift was at 6.65mm already, which is roughly 17*. Truck starts too good and runs to warm EGT wise to be timed that high. I swear it's stock, I never touched it, and the only thing done to it when I bought it was the stock plate was slid 3/4 forward.
 
Excuse the newb. question, but what are the CPL numbers, and how do you "decode" them off the stock plate? I got two lines off of mine yesterday. The lady I bought the truck from had her husband run off on her, thus selling the truck to me at a discounted price. Problem was, they replaced the old motor with a new one. I think it's a 215, but I'm not sure. It's got 913 at the end of the second line. Trying to figure out where "887", and "2174" numbers come from.
 
The CPL is the list off what exact parts are in YOUR engine, it is found on the left side of the timing cover

Thanks. Now, which is the more accurate way to check the pump? The CPL number or the I.D. tag on the pump?

The only accurate way to check the pump is with the i.d. tag on the pump. The CPL is for the entire engine (pistons, cam, injectors, pump, etc). For instance, my truck is a CPL 2174 which is a 180hp with a 911 pump, but i have swapped pumps (several times :) ) so now my CPL 2174 engine has a 913 pump from a CPL 2175 engine. Your usually safe checking the CPL only, but that's assuming no one has swapped out the pumps in the past.

Hope this helps,

Dave
