Ok, I've got the canister mounted where Factory Five recommends. (I'm doing a completely stock build.) I hooked up the two hoses to it, one from under the intake manifold and the other from the gas tank. I used the small diameter extensions on the top of the canister and the two large ones don't have anything hooked to them. Is this right? Do they have to have a dust sheild on these large openings or can I leave them open. Sorry, I just simply forget how it was set up in the Mustang. Thanks for the help!
