wanted: fuel cell

Looking for a fuel cell for my budget project, not looking to spend for a new one.

Would prefer 12 gallon or larger, but willing to consider a little smaller if price is right. Definitely not looking for a 1-2 gallon race tank!

MUST HAVE A SUMP, as I want to mount through trunk with fuel pump etc under the car.

Please PM with details/price.

Thanks!
