How to add a permeate pump to a Watts WP-RO4 system where the membrane and post-filter are integrated?

I purchased the Watts WP-RO4 system from Costco, which is the model that all filters and membrane are integrated in one piece. Now I want to install a permeate pump, but realize that it should be installed after membrane but before
the T-branch to the tank and the post-filter. However, since this is a one-piece system, such location is not available.
Is there any way to install a permeate pump to such a system?
Hi, Matt,
Here is the picture of my RO system with membrane removed: http://picasaweb.google.com/changfan/UntitledAlbum#5307947169654548738.
One the back, there is a tube at the permeate output of the membrane connecting to the tank, and another permeate output after the blue post-filter. Thanks.

Sounds like your going to have to do some custom fabrication. I don’t know your unit in particular but if you have a filter located after the membrane is it filtering the permeate only? If this is the case I would pull the membrane housing apart and normally there is a o-ringed shaft that the permeate is going through before it hits the filter. So would chop the filter off the permeate output and install my pump there. I would have to see how the end of the housing looks, if you can post pictures on photobucket and link them here we might be able to help you more.
