hicrop10 Posted October 28, 2020 Share Posted October 28, 2020 Will be trying to clean and seal the 2 fuel tanks off my b87.Was wondering what method you guys have tried?I have throught about hanging a tank in some sort of a gib to shake it about,not quite as young as I was back in the day.Would have just held it and shook it about.

DavCut Posted October 28, 2020 Share Posted October 28, 2020 Could you hang it and then use a shop vac through the fill hole? Not sure I'd try it with a gas tank but might be okay with a shop vac...

Freightrain Posted October 28, 2020 Share Posted October 28, 2020 I just bought new aluminum tanks! Only hard work was digging into the wallet to pay for them. Lol. At $700 each I really didnt think it was bad to never have to deal with 60 yr old tanks again. Quote Larry 1959 B61 Liv'n Large......................

Vladislav Posted October 28, 2020 Share Posted October 28, 2020 We did that kind of shaking. Hanged a tank on a pair of cargo straps, poured 10 liter of diesel in it and addad half a bin of gravel. Than shooked back-forth by hands. I had two young guys hired at the time and they did gym with the tank for 3-5 minutes a time changing each other. After 3 or 4 attemts they went to do something different and came back in an hour or so. Took them a couple of days for one tank (we made two) to get off rough rust but way not as after sandblasting. Of what I later read on here some folks attached a tank to portable cement mixer or a rear wheel of agricultural tractor and rest spinning for a few hours. Telling truth these ways seem to me more preferrable than shaking. Another possible alternative is cutting one bottom or a hole in the back side and sandblast through it. 2 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/64734-cleaning-inside-of-fuel-tank/#findComment-463179 Share on other sites More sharing options...
Maddog13407 Posted October 30, 2020 Share Posted October 30, 2020 i have filled B model tanks with water, ground the welds smooth, then took a sharpie and drew a line around and cut the ends off with a sawsall. have it sandblasted in and out and coated inside with Red Cote, leaving it a few inches from edge, then welded ends back on, poured more Red Kote i and swished it around where it was welded. all good for Diesel but if its a gas truck you cant put and garbage Ethanol gas in it or it will eat the Red Kote off Quote Link to comment https://www.bigmacktrucks.com/topic/64734-cleaning-inside-of-fuel-tank/#findComment-463239 Share on other sites More sharing options...
