RE: removal of metal tube in water pump?
If I remember correctly the tube is notched/slotted atthe end so you need to twist it like 90 degrees (counter clockwise I think) and then it should just pull out. It'll probably have some build up on it so a little wiggling while pulling hopefully should beak it free. As stated above it's just an o-ring sealing it

RE: removal of metal tube in water pump?
A common problem with the 1994+ Magnum water is the metal tube return line from the heater. In addition to it freezing in place due to corrosion, there is also a problem with corrosion making it nearly impossible to keep from leaking later after it has been re-inserted with a new o-ring even if the o-ring was properly lubricated prior to insertion.
You can try soaking the water pump in the cleaning product you can buy in supermarkets called 'CLR' which stands for Calcium, Lime and Rust cleaner.
I remember reading one post where a Ram owner fixed the leak after he replaced his Magnum water pump by coating the top of the metal tube where it inserts into the water pump with 'Plumber's Bronze' with a a glue like material filled with metal particles.
Another option is to replace the water pump with one from the 1992-1993 model year Magnum 5.2V8 which had back then a conventional screw in heater tube return line. See archived post below:

" I have researched the heater fitting issue and have found a replacement for
the press in tube with the o-ring. I work at a NAPA and mentioned this in
another thread a couple days ago, but I wanted to get good solid research in.
The water pumps on a early Magnum (92-93) have a threaded heater fitting and
are the same both in height of pulley and mounting pattern. They are also the
correct rotation on the impeller.
Here are some part numbers, whether you have a press on or bolt on pulley:
NAPA part#
58-447- bolt on pulley, threaded heater fitting
58-559-pressed on pulley, threaded heater fitting
I looked both of these pumps up for a 92-93 Dakota with a 318.
Both are rebuilts for about 50-60$.
Just thought I would satisfy some curiousity.

*EDIT*
The part number for the press-on pulley does not show up at NAPA's website.
