Ok this is probably really dumb, but I just bought an 89 RS from some guy in Chicage. I drove it about 1/2 way home and it started making a high pressure vacuum leak sound. When I got it towed the rest of the way home I popped the hood and this engine is so jury rigged it's ridiculous. I need to go through and replace prectically the entire Emmissions system because I don't know what goes where. Things are missing, sensors are not plugges in. I can't figure out for the life of me where the leak is. So what I am looking for is a list of every component for the emmisions system, the fuel system, and the ignition system. Thanks for anyone who can help. A beginning to end list would really help. It's for an LO3 TBI.

FUEL SYSTEM IGNITION EMISSIONS
1. Gas Tank 1. 1.
2. Fuel pump
3. Fuel Filter
