Uh...i didnt do any of that...i just swapped em out without removing the intake. It was a little tricky to get those small allen bolts started in the regulator bracket but once i had that done it was smooth sailing...all in all a fairly simple and straight forward install. To give u an idea on time requirements, i did the AFPR and a new 255 lph fuel pump in about four hours. no special tools required. good luck
