I just found a 1981 240D 4 speed in the salvage yard with a like new 2nd aux fuel tank in the trunk. It has a lable on it saying it is manufactured by "Bird Automotive Division". It is a custom fit type and aluminum. I'm guessing 20gal or so. It was connected to the main tank by a big fitting on the bottom of it to the main tank drain plug(I guess). Is this something out of the norm or something neat?? to me it looks like the pressure/weight of the fuel in the main tank fed fuel over to the aux tank doubling the fuel capacity. What would something like this sell for?? Also do the diesel Benz all 123 use this fuel tank or do they change from year to year?
I'm currently shopping for a 123 (240d 4spd) so I'm keeping it but if not I will sell it.
Thanks,
Hip

Sounds kinda neat. Take a photo. :thumbsup: Since our tanks are gravity fed, joining them at the bottom is the easy way to connect them. I have a second separate vegoil tank (aluminum) in the trunk but it's controlled by a dash fuel selector switch and two three-way solenoid valves.

Thats a great way to pump all the fuel out the main tank's overflow tube and onto the ground. I know, I did it with my auxiliary tank. I ended up getting 12mpg because of it.

Zedd,
please tell me about your 240d. Did the cost to modify the engine justify the performance gains? how did it affect the mileage?
Thanks,
Hip

IF ITS CHEAP BUY IT. THEN IF ITS NOT SOMETHING YOU WANT TO KEEP SELL IT TO ME!!! I HAVE 10 BENZ'S AND 7 ARE DIESELS!!! I CAN ALWAYS USE A 2ND TANK.

Bet you'll NEVER do that again!

Yeah, I've learned to live with a 13 gallon range.
I ended up getting rid of it on Craigslist a long time ago.
