Did this Saturday and Sunday.

I soaked it with 2 gallons of water with 1 gallons of muratic acid rotating the tank constantly for 6 hours.
Then I toppedit of the rest of the way and let it soak over night in the water and acid.
Then i rinsed it and used the metal prep on it rotating again.
Then I rinsed it with MEK and coated it with tank sealer.
Cure time is 92 hours.
There you have it!!

Thank you for the how-to. That is a big difference in the before and after. Did you have any problems with the tank before?

I've had it running now for almost 2 months with no problems or weird noises coming from the center console.

Nice work, thanks for sharing.

I have a rusted tank, and was planning on using straight vinegar.

Saying something is works right after the repair is fairly useless, now saying that something works after two years is silver .

If you can come back and say the fuel pump/tank is still running without problems after three years, that's golden! You'll have made it past the basic warranty period... a bare minimum goal that auto designers strive to attain.

No. I did have to replace the fuel pump about a year after, but it was under warranty.

I guess the MEK didn't damage the surface the metal prep left.

I guess not. I did it after the metal prep to get all the old chemical residues out. Plus if you don't use metal prep immediately after the muratic acid water, it will rust within 15 minutes. Also my thinking on the MEK was that it would remove any of the loose residues.
