Parts coming from Ireland Engineering, Pelican Parts, Mesa Performance, and a couple of members here and the e3 Facebook page. My mechanic was very generous and allowed me in to the shop yard to clean up the engine bay (somewhat) over the weekend while he's at home. Saw the old engine still hanging and tried chipping away at the almost stonelike sediment in cylinder #2. Coolant mixed with water?? Someone knows but I don't.
Will try separating the lower half of a short shift lever from IE (2002, but supposed to work for my application) and mating it to the threaded top half of my e3 shifter. I think I have to find a urethane(?) kit to make 'em stick together like friends forever. Have heard good things about Redline MTL 75w80, so I'll try it in the old Getrag 262. No idea how many miles are on the transmission (or engine).
Funny how the exhaust looks longer than the car itself. Oh- when I picked it up to load it into my CRV, tons of crap came out both ends; dirt, rodent poop, and rust chunks. I hope it'll at east be useable enough until I get a new one.
One question: will I need a different/separate fluid reservoir for my new clutch pedal? I didn't get a good look at it before thinking about it.

Yes, that's exactly what it is. It was packed into the block on my '69 and a sharpened screwdriver had a hard time breaking it up...

Thanks for the link, Chris.
Yeah, Dan- it gave up trying to chip it all away. Decided I'm going to keep the original engine just to open it up and see the guts.

Rover, I'm in Texas but I have lots of spare parts for bavs including a pretty full carcass out back. Let me know if you need anything- all parts are dirty and cheap-mostly free (there's a theme here somewhere), anyhow, I'm really slow at getting things pulled off the car but I'm always trying to clean up my little shop of horrors.

Thanks, Peter! Very kind. If you happen to have a stock e3 clutch and brake pedal in useable shape, I’m interested. I’ll make a list of parts I might need.

I used the 318is pump and e28 sending unit. The sending unit is the same for all e12, e23, e28 thru late 80s (16121153050) it is too short for the e9 tank and there are none any longer, not a big deal, a have four gallons left when it reads empty. The pumps have to be lengthened, have it brazed, don’t use fuel hose and clamps.

The four speed and auto use different length driveshafts.
Chris- I'm about to order the sending (16121153050) unit and wanted to know if the pump *must* be lengthened in order to fit the 318is pump/housing (or will it interfere with the pick up?).

Also, does anyone know if the automatic speedo cable will fit the manual 4 speed trans? It doesn't seem to want to go in.

The pickup is not long enough and must be lengthened, the sending unit fits within the pump structure itself. Did you check depth of tank?

N0- I just held up the factory sender next to the 318is pump and yep, the factory sender is noticeably longer. I'll be able to measure it tomorrow (it's at my mechanic's shop). I suppose I can just use the 318is sender. This set-up is "temporary" (maybe 2 years), so I could just keep an eye on the fuel level and fill up early.

The depth of the tank is 8.75" (floor to opening for the sender).
Given my stock (carbureted) tank has only a sender mounted in it, I'm not sure how I'd mount an external pump. Wouldn't the tank need to be drilled and another fuel (return) line be welded on? I don't see why the e28 sender wouldn't fit the 318is pump. It doesn't look like there would be any interference. Then again, how long/deep is the e28 sender?

I use the lift pump assembly and sender from an E28 in my E3. Easy to find in the boneyard, I have a couple of spares in the car just in case.

An E28 sender is this long:

The 318is pump has a return line, the e28 sender fits just fine inside of it. But in an e9 the pump pickup is too short (around 5/8” maybe?) and the sender is also too short as well for an accurate reading. There are no other BMW senders longer than the e28 one. I thought the e3 tank was deeper than an e9.
