Working on my pap's H as well, and there is about a half inch of varnish in the bottom of the tank as well as a ton of rusty junk inside. The junk comes out, but has anybody found anything that works to remove the varnish? The tank is good appeareance wise, so i see no reason to spend big bucks on another tank just because of varnish in the bottom.

Plug it off and fill it with E85 and let her sit a week or so. Ive used other means, but the guy who use to clean out my tanks told ne when he retired E85 was chaeper and in some cases better than anything you could buy.

I took my tank off. Put a piece of chain in it. Jacked up one side of my tractor. Attached tank to tire. Turned tractor on and put in low gear. Let the tractor tire spinning knock eveything loose. Then I put a liner in it.

We start with a hot pressure washer to get as much out as you can.
Beings its an H spend more time shooting anyway you can behind the baffel!!
Id use paint thinner to remove any leftover varnish, If the rust is still in there? I think Petra used Muriatic acic cut down with water to remove it. I use straight muriatic here at work then boil them out to neutrilize the acid.
Get it real dry and coat the inside if you want Orileys auto parts can get the liner believe the part# is REDKOTE

i power wash the inside then put in a couple jugs of CLR that can be found at any wal-mart

The plan is to get it lined, but I'd like to get the varnish out first. Acetone didn't seem to work well. There is still a little rust left in there, but for the most part, it's just the thick layer of varnish in the bottom. That baffle is a pain in the butt for trying to clean out the tank

Have you tried the gallon of caberator cleaner you can buy at parts store? It cuts the varnish out of my carbs and sediment bowls pretty darn quick

I took my tank to the radiator shop. He cleaned it, coated it and I painted it. $95 reasonable

I used MEK purchased at Ace hardware! Poured a gallon in sloshed it around, put the cap on and let it set for a couple hours! It had one half inch of varnish in the bottom! It took 2 gallon but it cleaned it all out! Rinsed it all out with water then let it sit in the hot sun to dry out the water. I poured a bunch of half inch nuts in the tank and rolled the tank around vigorously to take out the loose rust. Rinsed again with water! Fixed the leaks in the bottom. Then coated the massive surface rust inside with Os-Pho!

MEK will take it all out but keep in mind it STINKS and should only be used with good ventilation.

 

[emcasull454]

Yes it certainly does stink, and yes definately use it outside like i did!

laquer thinner .. grab a gallon at the paint soe.. pour in and let set.. agitate now and then.

once the varnish is out.. convert the rust using something like CLR or driveway rust spot cleaner..
