- 3/30/1999 Session #2 (90 minutes of work)
Install O2 sensor
Install EGR port plug. I got a standard 7/8"-18 steel plug. My old stuff

Install Ignition coil and old fulepump blockoff plate
Install Intake manafold

Removed washer tank
Removed old evap canister

- 4/10/1999 Session #4 (several hours to route the new fule line)
Installed new brake booster connector. The new factory one did not work.
Installed driver's side 5/16" steel fule line. I bent it while under the jeep.
- 4/15/1999 Session #5 (all nighter....16 hours)
Removed all old computers and connected wires
Installed fule pump and filter, this took a long time to get it the way I wanted it and without kinking any lines.
Installed all vacuum tubes, air vents, etc.
Water tested the computer (put it in a 5gal bucket while running)
Installed computer where the jack and vacuum can used to be. It did not fit in the new 'correct' location. Since I have dual batteries I had lots of space under the tray.
Installed the radiator and connected the new electric fan.
Too many little things.....But I Finished everying! including install of flex-a-lite electric fan
So, an estimate of 30-40 hours to do >everything< is not far off.....
Once installed, it took a minute of cranking for the fule pump to bleed the
air from the system (pipes, hoses, fule rail, etc) once the system got fule
it started right up. I noticed some strange engine idle for several minutes
while the computer learned how my engine ran. Things are great now!
The only problem left is sometimes hard starting, I have to crank for several
seconds before it starts....
and only a few other small things left, like making the Tach. work again.....
Photos: (more soon)
Ignored the install instructions until the end (seems to work well that way)
Used 7/8-18 steel drain plug for EGR hole
Got Motorcraft WA-10 dielectric grease ($12 vs Jeep's $18), I used it on every connector (including the water tight ones)
Got new washer fluid pump, Anco 64-01 (old one was falling apart)
Used MPFI fule hose where I could, note that it does NOT strech
Used new #5 EMT clamp for fule filter rather than that rubber thing
Installed the computer where I had space, and yes, it does work under water
I paid the local muffler shop to MIG weld shut the air injection holes
