very interesting. I was contemplating this swap myself. I went to www.hitechperformance.com (http://www.hitechperformance.com) and looked at the exploded view of the 12je pump. It appears that the intake bolts to some other piece which then bolts to the pump. So it looks like the intake should just come right off. If that's not the case I guess I would use loctite on the bolts and silicone for sealer. Let me know how this turns out as I will probably be doing the same thing very soon. Good Luck
