Whats the best/easiest way to delete the crossover tube and the AIR pump?

Just unbolt the crossover tube and plug the holes in the back of the heads(old spark plugs work for the holes). For the air pump either you need an air pump delete pulley for a 5.0 mustang or just remove the insides of your pump and leave the bearing.

Sweet! I can buy some regular plugs and put them in the holes too right?? And wouldn't I need a bypass pulley for a 5.0, or do I need one for a mustang??

They're marketed for mustangs. Only 'off road' vehicles can go without emissions, so the bypass pulley is fit drag cars. You can also go with a shorter belt and remove the smog pulley. I don't remember the length though. You can also take the cross-over pipe off and put a pipe cap where the solenoid threads on, then reinstall the pipe.

Alright, so the one from a mustang should bolt right on my truck right, its the same motor....

There is no need to delete the crossover tube. The air tube warms the cats at start up and provides o2 to help catylization. The crossover tubes are part of the egr. Defeating the egr will create more emissions and lowered mpg as well as illuminating the cel. Just cut the air tube. It will just pump air into the atmosphere. Or if you want to get creative you can connect it.to an air tank and have your own air compressor. For the cel pull the codes and you will know what is causing the problem.

The crossover pipe and the air tube are connected to the same hose off the smog pump. I traced all of it before I removed it. Also, egr delete doesn't always lower mpg. When I deleted mine due to a rusted-out pipe, my mileage stayed the same or slightly improved. And you're one of the only people on this forum who thinks the emissions are gonna jump enough for one truck to kill us all. And, the air pump don't put out enough pressure to be an effective compressor. Someone on here's tried it before.

I know my friend has a supercharged 302 in his mustang and he completely did away with the egr, he gets around 20 mpg and has power like crazy

I'm not saying one truck will make any difference but if everyone on this site who mentioned it deleted their emissions that's easily over half the posters. If that is a representative of the community and F150s are the number one selling truck in the us almost every year, well you can see my point. As for the air pump, if you contain the air and connect a check valve it works just fine for airing tires etc. It won't run an impact but it will work. My auto instructor uses one regularly on his Bronco. You are correct about the crossover, its not part of the egr. The egr has no effect at all on power. It only comes on during partial throttle, no load. Ie during cruise on the highway. During acceleration it is closed. During cruise it displaced air fuel mixture to reduce fuel used, reduce burn temp,( to eliminate NOx ) and eliminate knock and ping allowing for greater spark advance. There is simply no way to use as much fuel when the space is being filled with burned gases. And there is no need for extra power at cruise. There is simply no advantage to removing a properly functioning egr unless you just don't like how it looks. You had no difference because your system was not operating properly due to a rusted tube. I simply don't understand the desire to add pollution with no gain in power or efficiency.
