I pulled this tank out yesterday, along with the motor for Brandon and various goodies.
the tank was over half full
, so bonus i filled my V8 explorer (gas hog).
from what i could see through the sending unit opening the inside is shiny and clean, outside looks solid.
the bottom seems to be coated with an oily substance
size is 21" (at the top) x 48" x 7 1/2", and its capacity is 28 gal.
if you're interested, and don't think you could make the configuration work as is, i would be willing to move the fittings for you.
