Hoping to find a good fuel tank in the vicinity of New Mexico. E12/E24/E28 is apparently interchangeable.
The one in my td is rusted pretty thoroughly inside and the fuel cell alternative is questionably feasible. Really would be great to just get a good, original tank.

Re: Need a fuel tank
I can't help you with a replacement tank. I have a question about your existing tank: How do you know the tank is rusty and failing? I recently came across what I thought might've been bad/dirty gasoline in my E28. The mechanic drained the fuel, replaced the 2 fuel pumps and filter, and all is well. Even so, I've read that old tanks can become rusty, so the little rust particles foul the fuel. I'm interested in how you determined you have a rusty tank.
Thanks for your comments.

Re: Need a fuel tank
There is probably a combination of rust and petroleum based gunk. In the filler neck area it is pretty much 100% rust. Down in the body of the tank it's more difficult to tell. Essentially it looks like there was a cycle of evaporation and condensation occurring that concentrated the rust in the upper surfaces that were not immersed in fuel.
I have a Yamaha RD350 that looked much worse but it was essentially all gunk with near zero rust. The previous owner was running premixed fuel and had left castor oil mixed fuel in for a matter of years. Though it was a much smaller tank it was still a lot of work getting cleaned up. Spent many hours flushing, scraping, shaking, dumping, refilling and repeating the process.
I may attempt to rehabilitate the tank I have but the timeline on that is uncertain. I have an aftermarket fuel cell I intend to use for the short term but the best option by far would be a replacement tank.

Re: Need a fuel tank
If the tank has no holes, it's probably possible to clean it. I've done it couple of times and it's possible to to get rid of rust and make it look like new.

Couple of weeks ago I cleaned a very rusty e28 tank using similar method. Except, this time, I used nuts and bolts instead of rocks. Nuts are a lot easier to fish out with a magnet. And this time I used a diluted acid. You have to be quick to neutralise the acid when finished to prevent flash rusting.

Re: Need a fuel tank
I did something similar with the motorcycle tank. I think I would be tempted to cut this thing open and wire brush the hell out of it before I go that route again.
