Well InjectorRx has my fuel rail and injectors. Hope to see them back early next week.
I should get in my remaining hose from EGR to TB and with that all I need to do before I get the rails back it torque down the intake bolts.

 

Here is my fuel rail, note the capped Pulsation Dampener.

 

well everything is in and ran the car for a good 20 minutes thus far and no freakishness from the car in warning lights or anything. Hopefully this is DONE.

 

Finally bit the bullet and went after the valley heater return hose. Knew from the condition of the supply/feed hose replaced a few months ago that it was probably on last legs. Got to it just in time, as the diameter had doubled, the wall grown paper-thin and about to "give birth". Once you have 100k miles on your car, replacing these hoses (and the surrounding other heater/throttlebody connecting hoses) should be a must. Removing the intake manifold is not difficult, just tedious, as other members have discussed. A step-by-step is included in the shop manual and is relatively thorough, except for the fuel line/fuel rail disconnect. Thanks to the other members in this thread for their insights.


Only real problems were the EGR tube screws that attach to the throttlebody ( a small one-by-two block of wood under the ratchet solved this one) and the fuel line disconnect. I could not get the plastic disconnect tools to work. The collar on the simple plastic wrap-around was too thin to fully expand/clear the locking spring, and the plastic clamshell collars did not penetrate the opening deeply enough to get to the spring. The answer was the anodized aluminum, hinged, swing-arm tool. The five-eighths size (green one) was a perfect fit, as it immediately fully expanded the spring and released the interconnect. It is available singly and in a set of four at most all parts stores and internet outlets. Maybe if I pulled hard enough, the plastic tools would have worked, but the receiver on the fuel rail looks to have minimum strength/ no margin for abuse.

 

did you take off just the black plenum or also the metal intake part under it also? If so did you replace all the rubber and metal gaskets?

 

The 4.2L engine is simpler as to seals: the plastic manifold and aluminum fuel injector ports are all one piece, and there is just one seal per cylinder bank. Too bad I could not remove just the plastic manifold.

 

The black plastic intake to the aluminum injector ports have 8 indvl rubber seals that should be replaced if you take the two parts apart. i was told not to reuse the rubber seals. Jag does not sell those, you have to buy the complete black plastic intake with them in it. I got my seals from the same motor setup on a landrover/rangrover motor.
If you don't break these parts then yes there is one metal gasket per side.
