Anyone got a good idea as to cleaning my gas tank. It is an auxilliary tank for an old Bronco (fits perfect in a Model A) It has big chuncks of varnish flopping around in it, shook most of it out, but sure there is more still stuck in there. It is a poly tank. Any ideas???
If you put a couple foot length of clean linked chain it the tank and shake it around real good, it will knock most of what's stuck in there loose... Hope that helps..!!
yea try thee chain .i usea a few bicycle chains cleanind my tank in my 59 i got almost half a gallon of rust out that way .it works good
A friend of mine put some clean gravel and some water in his,and shook it up ,and then rinsed it all out.worked pretty well,this was on a 53 chevy tank.Hadn't heard about the chain idea ,it sounds good i'll have to try it some time.
Use the chain & if possible put it in one of those smaller cement mixers, if it'll fit! & leave it turning slowly....it works good.
Lo-tech post? Mine is real rusty and I had to cut out a chunk and weld in a few pieces, plan on using some sealer system to coat it inside. Best idea I came up with is to put in about a quart of pea stone (It does have a baffle, chain may be a bad idea, like permanently in there) and tie it to the back wheel on my backhoe. It will fit right in there, fasten to the wheel weight mounts holes with rachet tie straps. Move a few logs around, s****e some brush and pull the cap. Few more chores around the yard, and it should be empty, repeat if desired. Or spend time and money building a tumbler, say out of an engine stand and that hog roaster power unit?
I plan to use a friends tractor. Put chain and pointed rocks inside my tank, strap it to the rear tractor wheel, jack up the tractor wheel and let it run a while.
friend of mine just s****ed up some of the crushed rock in his gravel drive, put some water in with it and he and another buddy shook the **** out of it for an hour or so. Paul
just went back and reread your question, I missed that it IS a polly tank. I would think one of the solutions suggested in the solvent post would work. it's just varnish and dirt with little or no rust. http://www.jalopyjournal.com/ubbthreads/showflat.php?Cat=&Board=UBB1&Number=244404&page=2&view=collapsed&sb=5&o=14&fpart=1
One cup Muriatic acid in two gallons water- slosh it around and let it set for 6 hours then flip over let set again 6 hrs- then fill it up with water and flush out several times. allow overnite dry before using tank[wont harm plastic]those rocks and chains and cement mixer seem a little harsh on plastic to me
ALCOHOL/SHELLAC THINNER buy two gallons and do it twice and it will be clean as a whistle in 20 minutes. eats it instantly
I pull the tank out of the ranch wagon today.....I knew about the chain.......never thought about denatured alcohol.
guess its ok to leave any rust in there ...... jus kiddn![]the sender and pickup tube] are made of metal, guys......
I have some motorcycle tie downs that rachet around the tank then hang it with bungee cords. after I duct tape all the holes with the alcohol in the tank I bounce and spin the tank for 10-15 minutes then dump it and refill it with fresh alcohol and do it again and its clean and shiny. if it turns out to be a rusty old dog after its clean I like the POR15 tank sealer kit and I use the same bungee cords
