    hi I hope someone can answer some the questions I have. I have a 88 Fleetwood fwd, a few years ago I put on a 4.9 in it. the smog pump is on the engine because I thought I need it. can you anyone please tell me what do I do with all the parts that connect to the smog pump if I remove the pump. the cables, the hoses.

    Remove the hoses from the cat, manifold, and air duct and cap the holes. Remove the diverter valve. Remove the pump and install the substitute brace (from a 4.9) that bolts from the AC compressor to the bracket behind the timing cover. Install 4.9 length belt.
