Hydraulic pump: rebuild or replace?

[Wallace White <wallace@remdesign.com>]

I'm gearing up for a full-on assault on the embarassing hydraulic system
on my car. I've got the Jorgen rack on the way, and I started taking a
closer look at the pump last night. It is leaking primarily (quite a
bit!) at the seam between the two halves of the pump. Smaller leaks are
coming from two of the giant draglink screws; one of those is right
under the pressure line to the bomb, and I can't say for sure that
there's not a leak where the line meets the pump. 

I took a look at the Bentley's pump rebuild pages last night, and it
looks like there are a host of special tools involved. But I know that a
number of people on the list have rebuilt these. Does anyone have a
description of the process, sans VW 3642 or whatever? 

Am I better off just buying a "new" (rebuilt, probably) pump to replace
it? I don't have a pressure gauge to check it, but I don't believe
there's much wrong with the pump besides its seals. I've heard no
moaning to indicate a bad bearing. But, if the rebuild takes a lot of
time and won't necessarily fix it, I should go ahead and get a new pump.

Thanks, as always, for any and all help.
