Anyone know where I can find some hard vacuum hose cheap? Advance wants $5 for 3 feet. Napa has regular rubber hose by the foot cheapest I found, but not hard hose. I am tenatively going to replace all of the vacuum hose on my 2 5.0's and my roommate's all at the same time this wekeend and so I'm looking for like 20' (yes, all of the hard line under the hood) or something like that. Plus, I'm not sure if 3' (the incriments advance sells in) is going to be long enough for the longest single piece I need anyways (from pass fenderwall to rear of intake). Thanks.
