*Here are some tips on installing your 7.3 injectors- Always check the bottom of you injector cups for cracks and to make sure the copper crush washer was not left behind. In either case you will not have a good seal, causing major issues. Also,seat your injectors properly by lightly tapping them in until you hear them seat. Do not depend on the hold down bolts to get the job done. Keep your new set of Best 7.3 injectors sealed in the packaging untill it is time to drop them in the hole. By doing so, you avoid all the contamination and accidental damage to them possibly falling on the floor. 
Also, try to install your injectors indoors. Believe it or not, the wind is not your injectors friend. A gust of dust is all it takes to give your new 7.3 injectors trouble. 10 microns is all it takes to take down an injector, attacking primarily the plunger and barrel assembly. (Ben there done that) .
Get as much air out of your fuel system before you attempt to start your 7.3.Reason being is that you want to avoid cavitation(Air Bubbles In the Nozzle) while the oil pressure is down. Cavitation in your new Best 7.3 injectors  will erode the spray patterns under pressure, over time. Your high pressure oil pump has a maximum PSI of 3000. Cavitation @ 3000 PSI will compromise your spray patterns and that is why you should never rev your engine to get air out more quickly.We recommend starting at idle for a minimum of 45 minuets. 
When your engine has smoothed out, you should drive it for about 50 miles, in order to dissipate the last of the air. Listen to your motor for any hick ups. If all is well your are good to go, with a perfectly preserved set of 7.3 Injectors. Remember to call us if you have a situation where you can use our help.
