I am replacing the valve cover gaskets because they leak and drip down onto the intake manifold YUK. In doing the passenger side I had to remove the AC compressor and mounting bracket to get the valve cover off. (WHEW!) When I looked down, I noticed there was what looks like a vacuum port blocked off on my fuel pump. Anyone know what it should be connected to? I could not find anything in the 7525 manual,Thanks.
