The screens looked OK.. soaked the injectors in paint thinner for two days, then in gasoline for a couple hours after that. (the rail-side O-rings were not on the injectors for the soaking)

Actually, older O-rings have a tendency to swell up just a bit with time. That plus the fact that you had them out with no stress on them would lead me to believe this is what happened. Are you sure that the injectors are actually 100% seated when you stick them on the rail?

I stuck 'em in as hard as I dared push 'em.

I'll push 'em down again pretty hard when I go to put the last 2 in and bolt down the fuel rail.

OK.. got two replacement injectors today.. thanks to Tom. Problem now is getting replacement pintle caps. Specifically asked AutoHole and the Ford dealer for them a few days ago, both said no. I was just told Napa SHOULD have them, but their website does not list them. (and they list something like 4 pages' worth of stuff for injectors) Only place I haven't tried is Advance. I might go by there today when I'm "oot and aboot". :p

Thanks to my taxi-type services this past week or so, I should be getting some financial help on getting that fuel pump for this car, and the 95A alternator I need for the other T-bird. Hopefully by this time next week this project should be moving along again.

Another one back from the dead today.

Just placed an order for two injector seal kits. Each kit is 2 O-rings, a pintle cap, and that little plastic washer. I soaked the injectors in paint thinner and gasoline for a few days just to make sure they were clean, (but I think Tom said he tested them before shipping and they were fine, so this was largely redundant and driven by having way too much time on my hands) and even taped off the ends to shoot 'em with a little bit of 500 degree gloss black to match the quickie touch-up paint job I gave the other 6.

Ground shipment.. should have 'em next week sometime. Now I need to work on securing the replacement fuel pump. My best opportunity is probably this coming weekend. (for delivery sometime next week, as well)

On an unrelated side note about that car: I found out for sure that the windshield leaks when it rains. It's been dripping down onto the carpet over the tranny/driveshaft tunnel. I dread pulling up the carpet someday.. but at least now I have some Damp-Rid inside the car, along with a catch can.. and at some point I'll try to seal that up. It's dripping down the wire for the auto-dim sensor on the rearview mirror mounting.
