debi, you did not tell us what engine size your F250 is. To pass emission inspection I think you will further need an EGR valve. An Air (SMOG) pump, which fits into the bracket the alternator also fits in and runs from a separate belt from the alternator. AIR hose/tubing/valve. This was a 3-way: one output went into the exhaust ahead of the cat; another went into the heads via a manifold at the back of the engine. Charcoal evap. canister. You will need two if you have dual tanks. Various vacuum hoses, one-way valves, thermo valves, etc. I attached a few images, but can not be more specific due to engine size. Hope this helps somewhat....let us know. Good Luck

Besides the great images, there is lots of info [http://www.supermotors.net/|on here]

debi, you did not tell us what engine size your F250 is. To pass emission inspection I think you will need an EGR valve, which on the 351 HO was under the carb and used a passage in the cast iron 4V manifold to get exhaust. So, if it is put on another intake manifold it will look good but won't work. An AIR (SMOG) pump, which fits into the bracket the alternator also fits in and runs from a separate belt from the alternator. AIR hose/tubing/valve. This was a 3-way: one output went into the exhuast ahead of the cat; another went into the heads via a manifold at the back of the engine. Charcoal evap. canister. You will need two if you have dual tanks. Various vacuum hoses, one-way valves, thermo valves, etc which actually control the EGR, AIR, etc. I attached a few images, but can not be more specific due to engine size.
