Thanks for your reply. I really want to keep the canister that is on the truck now because it has been decorated.

Your comments have given me a new idea though. I have seen some new cars that use cannister type filters. Perhaps I can find one of those that I can adapt. I am sure that they have been built to handle high pressure and volume. Thanks again.
