I actually had no issues installing the injectors into the rails. Very mild lubing of the plenum ports and very minor lubing of the fuel rail ports. Then some slow but constant twisting of the injectors as you apply pressure to put them in the plenum. Getting them in the fuel rails was alittle trickier but not so bad really. I laid the rail over the injectors and lined up the ports to them. Applying a little pressure to the rail while slowly twisting the injectors a little at a time and they worked their way into the rail. The rail mounted up right to the plenum with a perfect fit.
I assumed I was gonna have trouble getting them in since i played hell getting them out of the OEM fuel rail, but I was pleasantly surprised that it was the opposite. In all, the o-rings were still in great shape (only a couple years old) so I didnt have to use any of my new ones. Good to have regardless.
My only issue this weekend was getting the nut off of the crank pulley. I hunted all over for a crank holder. No shops nor any of my tech friends had access to one (found one that fit various Fords, but no luck on my pulley). So, I ended up using the serpentine belt. I did the old wrap and fold of the belt around the pully and cranked the nut in the opposite direction. Worked like a charm (with some shop gloves that is.... hard on the hands). It's a risky tactic if you want to re-use your belt, so I suggest only doing this if you are replacing it. In my case, I was replacing all belts and gaskets so I had nothing to lose.
Looking over some stuff at quitting time last night, I was checking out the wiring. Does anyone recall what harnesses, if any, they had to splice and lengthen? Looks like there is gonna have to be some extension for the wiring to reach the new throttle body location.
