To go along with the gas tank fun I spent some time under the hood on the fuel system as well.

I pulled the fuel rails and injectors to clear out the old fuel replace the fuel pressure regulator. While apart I also cleaned the gunk off the outside of the injectors and replaced the o-rings. I used some Berrymans B12 and an old toothbrush to scrub the gunk off, I think they cleaned up pretty well!

The rail end on this one didn't clean up as nice as the others

Cap of dirty B12, it started clear:

I have a question about these two vacuum lines and which one goes where?

And does anyone have a lead on where to get a replacement rubber vac line elbow?

that vac line elbow is discontinued.  You can use the 90 degree boot from a spark plug.

as they say a picture is worth a thousand words! Thanks!

I'll have to look and see if I have and old spark plug boots laying around... I did see that Dorman has some soft 90* connectors available, not sure if they are the right size.

Good job! On the impalassforum.com, babywag is selling the correct o-rings that seal the crossover pipes in the fuel rails. I'd strongly suggest getting those and replacing them too.

We borrowed a 5 gallon fuel jug from a friend so I could put some gas in the tank. I only have a small 2 gallon can. Then I finished up reinstalling the injectors and fuel rails today. The other day I got most of it reassembled but not bolted down. Then popped the battery in place and turned the key to the run position. I cycled the key a whole bunch of times to purge the air and fill the fuel lines. It took 3 or 4 cycles until the system was purged, but I probably cycled the key 15-20 times total. I was also checking for leaks all over as I had everything disconnected at one point. The tank was out, change the fuel filter, ect. No signs of leaks!
I did not try and start the car yet. I want to let the fuel sit in the system for a bit to help dissolve what ever left over gunk might be in there and also verify all connections are good.
Next up will be an oil/filter change before any start attempts are made.

So I changed the oil and filter today. Used an AC Delco P52E filter, in the future I will probably go with a Wix. I also used Super Tech full synthetic 5w-30. The old oil looked a bit funky, not surprising since it's at least 14 years old! I also put in a new air filter. To fix the deteriorated vacuum elbow I used a spark plug boot like suggested above, fit perfectly!
I waited for the wife to get home, since it is her car, to let her try and finally start it up. It cranked over beautifully but no go and no hint of starting. The oil pressure gauge showed good pressure. Tried is a bunch of times and it finally coughed slightly like it wanted to start... I said lets let it sit and go eat dinner. I figured that the injectors all cycled a bunch of times and got fresh fuel into and maybe through them a bit. I could also smell gas very faintly. So we let the new gas soak and possibly dissolve the gunk in the injectors.
We went out after dinner, maybe an hour later, and tried again. This time it cranked and sputtered a few times. And then success!!!!! She fired up and ran pretty rough for 15-20 seconds and then settled down and idled perfectly! We let it idle for 10-15 minutes to let it heat up.
We tried out the HVAC system, AC doesn't work, not really surprised at that. The heat blows good and hot. Most all of the electrics seem to work. The passenger side mirror doesn't move but you can hear some noise in the housing.
I moved the shifter through the gears and the transmission feels like it engages OK. I moved the car back and forth about 10 feet, all the room I had.
Overall we are very happy! Smile

Good work. Bringing them back to life is always fun.
