Fellow 2003 3670RL owner,
My 3670 pump did the same thing about a year ago. I found the O-ring online and replaced it with minimum effort. the only tricky part is to remove the hydraulic fluid from the reservoir first. here are the specs on the part: MSC Industrial supply, pkg of 2 Viton 70 O-rings #348, part #02245827 and cost about $10.96.
Make sure to thoroughly clean the reservoir area and don't forget to remove the old seal from the reservoir groove before re-assembling it.

Good luck.

I would have used a boat bilge pump
Pulling a 2004, 2980 RL an oldie but goodie.
