Hey guys I have a 1995 ford 150 I want to removing all the Emissions stuff it has the tube that goes from head to head and the tubes that goes to the pump up front. what all do I have to do to take that stuff off and I'm replacing the oil pan and pan gasket should I put sealant on the corners of the gaskets? Thanks

Why do you want to remove the smog equipment, you'll have absolutely no gains from doing it performance-wise, I can tell you because I've had to remove most of mine for lack of spares in my country, my mileage actually went down about 2 MPG...

You just need to plug the two holes in the back... I can't remember the size of the plugs required right now, you can remove the Thermactor (smog air pump) and run a shorter belt (some engines might require a delete pulley, see that the new belt route won't cause problems). There are some issues with the EGR, I've been told you should leave it alone, take the pump and the tubes out and be done with it.

Assuming we're dealing with a '95 5.0L here...
The crossover tube at the back of the heads can be removed. The holes in the back of the heads can then be plugged with a pair of 5/8-11 x 3/4" long bolts. Leave the vacuum lines that supply vacuum to the TAB and TAD solenoids, but plug the top port on each.
If your FEAD has the upper idler with the tensioner located just below the alternator, you'll need a 94" belt (940K6). The routing of the belt is as follows: from the crank pulley around the water pump pulley, to the ps pump, to the ac compressor, under the tensioner, to the alternator, then back to the crank pulley. You won't use the upper idler pulley in this configuration.
