maybe get a chunk of sheet metal and bend it, sticking a corner under the back edge of the tank. something that would keeep a t-post or other cargo from puncturing it during hard braking.
then when you can find one in a junkyard for cheap, fix the OEM tank, and run bio in the plastic, and straight in the main, and have a selector valve.
GM Guy, that's a fricking good idea, now to find a place under the Burb to fit a flat tank of sorts.
Thanks for another project idea, like I really needed it.:rolleyes5:
