Fly High Sacs

[bjeremi]

I purchases a couple of fat sacs off of ebay that I believe are factory sacks for the rear compartments in either a supra or a moomba. They are the 275lb sacks. My question is I want to eventually plumb these in but that will be a winter project right now I just want to use them until the seasons over. There are three fittings on the sacks one with a cap and two that without that appear to be just some sort of quick release fitting. What fittings do I need to plug these two open ones and fill the sack manually with a regular aerator pump? Do I need special ones from fly high or is there an alternative. Thanks.

Can you post a pic? Waterbed parts can usually be used for plugs on fat sacs. I have fly highs and I don't remember any of the sacs having special fittings.
