So some years ago I used to work in the divisive VO industry before getting sick of it and going into fleet service, and now im doing property/real estate type stuff.
Since I was doing conversion stuff back when, I maintained some contacts and have been storing a bunch of these plastic tanks for a company called "Snap Green Tech"-
Recently ive been expanding my rental property activities and im looking to build a mezzanine in my space where i was previously storing overstock stuff for these guys among other businesses (im also storing about 20 boxes of christmas ornament stuff for chrissakes). Essentially I need to make some space, and they have given me permission to sell just the plastic tanks unmodified on my own that I have sitting here, and not part of a kit with heat exchanger and bracketry or whatnot.
Ive got about 20 of the big 18 gal ones kicking around, there might be 2 or 3 of the small ones left over from a previous storage shipment. These things are pretty awesome, they've been product tested according to VMSS specs, if you would like more info on the specs they tested them by, please visit the above link.
The ones I have are not yet prepared to fit a heat exchanger, so you would be getting the tank, a pair of caps, and a roll over fuel vent. (you will have to cut the port for the vent in the raised boss) Mounting and fuel pickup would be up to you, and you can use this as a big aux tank, do VO stuff, whatever you want. All I have to do is number them for federal standards and pass that info back on to the manufacturer for records.
some pics of the things. I got into storing some when I originally bought one for my old 240 and they needed overstock space (and I knew the guy). I have 3 of them for personal cars, one used for VO, the other two are just aux fuel tanks. dimensions I took from their website- 35.5” L x 12”W x 13.75”H
PM if you'd like a different pic, or if you are interested in purchasing one. Shipping I can quote for you, they are pretty light. Based on location, shipping might be included if its under 20 bucks or so for me.
