I went through this with the red tag pump off my '86 5ktq. The pump was
leaking at the joint between the pump body and the rear accumulator. I
pulled it apart and replaced the o-rings. It still leaked, but not as much.
I pulled it apart again and ran a bead of RTV silicone around the outer edge
of the body. This stopped the leak for about 2 weeks but then it started
seeping again. I was about to pull it apart again and use an old aircraft
mechanics trick for sealing crankcase leaks - run a silk thread around the
joint and bolt it up. I even got some silk thread, but the car was totalled
before I tried it out. The green tag pump on my '91 200q has never leaked,
for which I am profoundly thankful.
I think there is another o-ring inside which can be changed - it does
not come with the rebuild kit and has to be ordered separately.
