Two poly plastic HDPE fuel tanks for projects or GM trucks in Apopka, Florida For Sale

$20 for each-make me an offer for both!
I have two HDPE (High-density polyethylene) fuel tanks, also called poly tanks or plastic tanks, for GM trucks for sale. These are high quality, thick, corrosion and impact resistant. I do not know, and cannot guarantee, exactly what vehicles they fit on, just Chevy and GMC trucks, or possibly vans. I will tell you what I have found on them however.
They could also conceivably be retro-fitted for a generator (this is what I will do if these are not sold), farm equipment or used for other projects in need of a storage tank (maybe not potable water :)
I know from looking these up that they are quite expensive new. Please see the specifics below and pictures for more detail. Email me with inquiries and I will get back to you asap. I meet people at a public place within a few miles of my residence. I will remove the ad when the item(s) are no longer available.
The first, larger tank is 34 gallon (this is an semi-educated guess because the dimensions are similar to other 34 gal tanks) Poly Plastic Gas Tank for Chevy/GM -- should fit a broad range of the most popular full-sized trucks. It looks like it fits on the inside of the frame lengthwise. As seen in the picture, the fuel pump sits near the middle and the fill hose is on the side.
Basic dimensions: 15" x 61"

The second, smaller tank is of similar construction, though it looks more like one that would sit at the rear of the vehicle, maybe a smaller mid-sized truck.
