Well I figured I should hit all candidates in the fuel system while doing my injectors, and Jerry has the kit for the fuel rail, can't be that bad right?
Except it's 9 freaking o-rings! That's not so bad, at least these seat in steel so I expect I can be a little less patient than using steel tools on the injector housing. But how do you get at these two??? The retainer is welded to the block? Doesn't unbolt like the others. Still just pressed in there? I don't want to wiggle something out that shouldn't be wiggled... From the other side I can see them in there under compression but I don't like forcing things apart if I know I have to put them back together. They don't look degraded like the ones at the car/engine junction did. Man am I feeling like I'd like to be lazy... Thanks, - Jeff

Well these two are really kicking my butt. I changed all the rest, being really careful with the dis-assembled basket of snakes, and tried for 1/2 hr to tap/wrestle/finesse the feed/return apart with no luck. I've got it all back together but leaving those two untouched is bugging me - I did find a couple rubber ones that seemed degraded...
Argh, - Jeff

Did you do static FP tests before breakdown?
If it was good, with no leakdown, maybe don't tangle with them... I had no leakdown before I re-worked top end (until I sheared off one ring), and didn't breakdown the cross-over / FPR assembly. More Rail breakdown snappics post #89 here The O's that I did pull I just soaked in Trans-X. THat stuff seems to integrate molecular structure of latex - really swells 'em up too...

Thanks Schrade (nice pics btw!) - FP seemed stable enough although I didn't do it for long. From the looks of a couple of the o-rings, plus the two in question appear different looking in from the business end, I'm giving it one more try. I took the rail back apart and have the mating block in a vice and am trying to shake these puppies loose, with a touch of PB for good measure. I will give up after 1/2 hr of this and not feel guilty - although I do worry that if I succeed they may be impossible to re-mate. I think these are tighter than the rest by design since they don't have an overclamp - the welded piece "just" clears the boss on the tube.
Somebody burned up some midnight oil designing, then figuring out how to manufacture, this bundle of snakes... on edit - I'm going to throw this thing in the freezer a while and maybe add some freeze spray... Cheers, - Jeff

Jeff,
The two you are trying to remove are permanent. There are no seals to be replaced. 7 seals are for the pipes to the rails & regulator in the back, the other 2 are for the fuel feed & return block, for a total of 9.

Funny thing is I can see a seal inside what I presume to be the pressure side. I figured something was up since the retaining clip is welded not fastened. Thank goodness you got to me before I succeeded, or started trying too hard! Cheers, - Jeff
