Best gas tank replacement behind seat.

[t76turbo]

I have searched and read multiple threads.

Most end up with recommendations to move to rear mount tank. I will do that one day but want to replace behind seat tank now and will swap later. Lots of reasons for this but a few are my air bag pump and tank are mounted in rear now where relo tanks go. I don't want to move that till I replace that air bag setup with the porterbuilt brackets and twin pumps and tanks. Can't do that now.

I read some that got a tank from lmc and had lots of problems.

Are there any companies that sell replacements that are less prone to fitment issues?
