Columbus..the 1957 IH 4x4..

Yep Robert...I already did the chain thing when I did the initial flush....I'm gonna give the chain thang another shot and see what itll knock loose...
Yeah John...I've read thru that thread several times...it starts out with him using evaporust...then everybody else's rust removal trick...but I think the rust neutralizer I used took care of the rust...at least what I can see...

[mongocanfly]

So I dumped a half gallon of purple power in the tank,,,added the chain back and several gallons of water...sloshed it around for about 20 min...I got alot of crap out of it...this isnt 1/10 of the crap I got out...just what I caught with a rag..
I gonna take it to work where we have a steam hose...more purple power and chain...well see what extra hot water will do...

[8man]

Dang, that's a lot of crap in a tank. Good luck with it.

[mongocanfly]

well shucks......that didn't work....
I poured in purple power and stuck a straight steam line in the tank and let it run for 30 minutes..let it cool some ...then threw in about a dozen 1" nuts...rolled it around for awhile, dumped it and still got crap all in it...so I filled it about half full of water, added more purple power ,stuck the steam back in and let it boil for about a hour...dumped it all out ,flushed it good .....
and it looks like crap..!!!
got some batteries in my bore scope so I can see all around inside...
and it looks even worse now that I can see the whole inside....
maybe I can find a radiator shop...
if that don't work I don't know what ill do...

[Ol Blue K20]

I'm guessing you need a rad shop to clean it. It's got a lot of stuff left in it? (Notice I said stuff).

[mongocanfly]

Yeah...its got all kinds of black scale still in it....even the direct steam wouldnt knock it loose....
Definitely dont want that crap going thru filters,pumps and injectors ..

[jjzepplin]

Make a new tank?

[mongocanfly]

Possibly....I searched the net last night for gas tank cleaning...there are a few options out there...several companies that do it actually cut holes in the tank and sandblast the inside...then weld the patches back in ,and then seal the tank inside and out....I sent a quote request to a place in Ga..I'll see what they charge....if it's to high I may do it myself...or build a new tank....like I needed more to do...

I wonder if CLR would dissolve it?

[mongocanfly]

Hadn't thought of clr John..I'll grab a jug and pour in it...but I have my doubts...

[68Timber]

Yeah I’m guessing at it. But you’d think there’s something simple and available otc that will dissolve that stuff.

[mongocanfly]

i think the epa got rid of all the good over the counter stuff...dang epa

[68Timber]

Last guess. Reckon Berryman Chem dip would clean it up?

[Ol Blue K20]

I'm thinking cutting the hole and sandblasting is gonna be the answer.

[mongocanfly]

I poured a gallon of apple cider vinegar in the tank this afternoon...gonna let it soak and see what that does...
at work we have a keylite chemical cleaning tank I thought about trying..its some stout stuff..will eat up aluminum..wont hurt metal...but I'm not sure how the filler neck is attached (its not welded,, I think it may be soldered)and worried about it coming loose...
ive got some carb and parts cleaner ,,not sure what brand it is though...no label left on it and ive had it for awhile...

[rgunlock]

I had a carburetor full of crusted up gunk and it was suggested to me (on this forum) that I soak it in hot Pinesol. I didn't actually heat up the Pinesol, but I was pretty amazed by how well it cleaned up the carb. One guy said he diluted the hot Pinesol 20:1 although I just used it straight. Might work for your tank???

Funny you mention that. I had a CB750 about 12 years ago and it had 4 carbs. The guys on the CB750 forum swore by soaking your carbs in Pinesol if you ever let the bike sit and the carbs gunked up.

[mongocanfly]

Funny yall mention pinesol...when you suggested berryman,I googled it and a video popped up on berryman vs pinesol....https://m.roadkillcustoms.com/carbur...k-alternative/

[mongocanfly]

Well it seems like the vinegar may be working...I dumped a gal in yesterday and checked it today...it was sitting on the bottom and the bottom looked fairly clean...but the tank bottom was the best looking part of the tank...I dumped in another gal and have it on its side now...we'll see how it does on the worse looking stuff....

[nitroracer]

If the deposits are more rust than foreign material you might be able to try electrolysis. Fill up the tank, find an anode and run 12V through it.

[mongocanfly]

thanks nitro...right now its the deposits that I cant get loose...
ive seen a lot of gunky gas tanks in my time, but ive never seen one this bad...
gonna add 5 more gallons of a.c.v. in the morning and let it sit...we'll see what happens

[tune_1]

I’m not sure if it would make a difference but hienz makes a cleaning vinegar that is 6% acid instead of 5. Looking forward to your results

Dwight

[mongocanfly]

thanks for the info Dwight...I didn't know there was different % on a.c.v...I just always grab the Walmart brand...I know the name brand stuff is nearly double the cost of wm..I use a.c.v. in my meat marinades for my smoker...

This is news to me. Now I'm going to check and see if the % is different between cheap and name brand. I also use it a lot for marinades for the smoker.

[mongocanfly]

Well I checked walmart,kroger,and heinz brands of both white and apple cider vinegar...all of them are 5%...

On another note..the vinegar ain't working...the tank bottom is somewhat clean but it's not cutting anything of the sides or ends....looking more like I'll be cutting holes in it and sandblasting ....
