That's a surge tank. One pump (the little squarish one) is a lift pump, that fills that little tank. The round pump is the high pressure fuel injection pump. Seems like either some part of this car (perhaps the fuel tank) didn't come from a turbo model and so someone has rigged this surge tank to circumvent the need for fuel tank baffles, etc..... Don't be so hasty to delete everything you see. You need to make sure it doesn't need a surge tank before you go de-engineering the car. GD

Get our your lathe and some bushing bronze. Only way any of that is going to get fixed at this point. All those parts are NLA. GD

I'm not sure, the manual only shows one, I think one of the previous owners just put a new one there and left the old one.

i will take this all into consideration and start testing the above mentioned. Im only 23 and this is my first teardown and rebuild. Much to be learned

They've already been replaced... twice

Misfires aren't caused by the TPS. You are barking up the wrong tree. Fueling is done by mass airflow and timing largely by RPM.... The TPS would have to swing a LOT to make considerable changes in timing enough to cause a misfire. TPS is largely used for acceleration enrichment and transmission kickdown, etc. Not achieving 100% isn't really an issue as anything over 80% is generally considered wide open for purposes of tuning (the point where the ECM enters power enrichment mode). Figure out what's wrong with your ignition or fueling or compression. TPS isn't your problem. GD

Ok that’s out of the way so it’s story time kids. Can’t do this today with a contemporary Subaru. We were working a job across the Sound here and needed to take the ferry boat. It’s about a half hour trip. As soon as we exited our vehicles the rest of the gang went up to the lounge and generally left me alone there with all the vehicles. One guy came back to check on me. I had a FWD 1986 or was it 85? GL fivespeed - the legend ! Not kidding. That right rear wheel bearing got swapped out , hand packing the new one and was lowering the car back down as the ferry slowed to dock. I got applauded ! The guy maintaining the paddock watched most of it. You could see his face , not that I looked up much during the work , but as time went on he showed extreme relief!! “Man I’m glad you got dat dun” Mine was one of the cars at the rear so I would have blocked a lot of people. thanks for reading. Best audience ever ! Be well.

Dash is a little different on an 81 just posting for the heck of it.

Turns out the switch for the Center Light was bad. Pulled it out of the dash and it looked like it had been underwater with rust happening. Swapped it out with a better condition switch and the 3rd Eye is active again. Thanks for your posts el_freddo and Subi81. Feel as though I understand the Center Light setup more now, even though I didnt have to dig very far. Checked grounds and connections, then checked that the bulb itself was good, before trading out the switch itself.
