    Hi Jim, new here but a FTE and Ford vehicle enthusiast since my 55 ford Niagara. My question refers to the air cleaner on your 460 with the second air inlet controlled by manifold vacuum. I was looking at a post from 2011 and I saw you posted a pic of your air cleaner. I have one on my E350 RV with a 351 W. Its a non catalyst with 2 air pumps like your 460. Someone messed up the vacuum lines (missing and plugged) I need to verify that the manifold vacuum that drives the air pump dump valve that feeds the air cleaner comes from the ATC in the air cleaner. Thats my last line to figure out. I have backfiring in the exhaust on engine decel since that dump valve was disconnected and continues in default mode and pumps air to the exhaust.
    Gary said to pm you LOL.
