Ok, so pump water pump started leaking from the weep hole and I was about to order a Bosch replacement when I saw this thread (great BTW).
Couple of questions:
Where is the best place (price wise to get the IH pump)?
Which coolant filter should I use if I am running Rotella ELC?
Also, please convince me this is a better way to go. I am still debating the cost factor. New Bosch pump with coolant bybass filter will run me about $220 and no need for modifications. Not sure what this will total out to? Sorry, money is tight right now an thank you much!

Here are some part numbers from NAPA. You can look at them in detail at NAPA's website to make sure they are the same as the water pump used by the Original Poster of this thread. I found them by searching on a replacement water pump for a 2000 International 4700 with a T444E engine.
Part Number: TWD ASCWPHD7315
Part Number: TFW 43545HD
Part Number: TFW 43545

I run a Donaldson ECF4085. Probably the easiest to find is a NAPA 4070. Basically any coolant filter with 11/16-16 threads THAT HAS NO CHEMICALS INSIDE will work. Common alternates for the NAPA 4070 are:
AC-DELCO - WF108
BALDWIN - B5134
BIG A - 96070
CARQUEST - 89070
CUMMINS - 3300721
CUMMINS - CW2011
DELUXE - WD-7320
DELUXE - WD-7330
DETROIT DIESEL - 23524403
DONALDSON - P554685
FLEETGUARD - MK13092
FLEETGUARD - WF2050
FLEETGUARD - WF2077
FLEETGUARD - WF2101
FORD - E7NN-8A469-A
FORD - E7NN-8A469-AA
FRAM - PR3383
IHC-NAVISTAR - 1610682C91
IHC-NAVISTAR - 1820358C1
JOHN DEERE - RE11992
KENWORTH - KW2011
LUBER-FINER - LFW22038
LUBER-FINER - LFW4685
MANN & HUMMEL - WA940/18
MERCEDES-BENZ - 235 244 03
NAPA - 4069
NAPA - 4070
PUROLATOR - W54451
WIX - 24069
WIX - 24070
WIX - 24087

There's another line of coolant filter that offer increased filtering efficiency, but they tend to come with higher prices, they are:
High Efficiency Coolant filters without additive
BALDWIN - B5088
BALDWIN - B5090
CUMMINS - 3098689
CUMMINS - 3098690
DONALDSON - ECF4085
FLEETGUARD - WF2122

Great info, thank you!
Is this really worth all the work?

You're Welcome.
I don't know if it's worth it, as I have a Dieselsite filter with an OEM pump.

Does anyone know if the upper radiator hose for the International water pump goes through the serpentine belt or around it? I already have the around the belt (dual alt upper hose) and do not want to go back to one that goes through the belt.

My lifetime warranty water pump from O'Reilly has failed after 2 years. I had few options as I was on the road at the time. The warranted free replacement will not be going on the truck but will be used for an emergency spare. I will either go OEM (apparently not airtex as many on DieselStop swear) or the International. I do not currently have the coolant filter but do have Diesel Sites 203 degree thermostat and billet housing.

Judging by the pictures, the International pumps uses the same thermostat housing, but it DOES NOT use the same thermostat. So your existing hose should work just fine.

I am almost done with my install on my 2003 7.3 Excursion. The molded hose did not fit for me either as it was too short. I am going with the gates flex hose. Good news! this mod is now available as a kit from Dieselsite! They are currently out of stock waiting on more of the lower radiator hose that they had custom made. Their price is about the same as I spent on just my water pump from the local International dealer. This is a no brainer as I have been chasing parts for a couple of days to complete it.



New 7.3L Ford Powerstroke water pump with Coolant Filter all in one! Finally a complete bolt-on system that utilizes the International cast iron water pump, modified to fit the 7.3L Powerstroke. Fits all 1999 -2003 7.3L engines.

This kit comes complete for a super-clean install! Includes:

International thermostat,
DieselSite billet aluminum thermostat housing,
custom lifetime silicon lower radiator hose,
stainless steel housing bolts,
all plumbing hardware for conversion
and high quality bolts for installation
Will not work on Dual Alternator Trucks

When they get the hoses back in stock I will buy one to replace the flexible Gates hose.

Other than the coolant filter boss, I'm still confused as to what tangible, measureable benefit people are perceiving with the IH cast iron water pump over the Ford aluminum water pump?

"Other than the coolant filter boss, I'm still confused as to what tangible, measureable benefit people are perceiving with the IH cast iron water pump over the Ford aluminum water pump?"

Other than the eventual problems of cavitation and electrolysis associated with so many dissimilar metals, high mileage AND a spinning iron based wheel (creates an electrical charge) that further aggravates the problem along with a steel thermostat housing that corrodes against the aluminum housing, not much.
