Okay here goes, I have gotten two quote's on a new 75 gallon aluminum tank and Wow this is not going to be cheap.700 to 900$ I looked in the tank and is speckled with rust, my question is, is there any way I can clean the tank without removal? If so what do I need to use? I have water separators and inline filters before the carbs. Whats the worst case scenario? filters clog and engine stall? I am going to replace it but would like to get a year out of it if possible.

Don't know if I done right but then I could remove my tanks.
First I drained them, removed them, flushed out the residue (rust and stuff) with H2o, and soaked up the remains.
Then I poured a gallon or two of acetone down them and drove around with them in my truck bed for a couple of weeks to slosh it around real good and cut the varnish. Could have put some ball bearing in there to help but why get more anal.

I bought a 1974 SAAB Sonnett a couple years ago and the gas tank was totally messed up. I pulled the tank, took out the sending unit and dumped probably two gallons of sludge and stuff that looked like white paint chips out.. Then I washed it out with my hose, threw a bunch of nuts an bolts in it and sloshed it around, banged on the sides with a rubber mallet, and washed it out again. I repeated this until not another speck of crap came out. Then I took it to a self serve car wash and blasted it out with high pressure water and soap for about ten minutes. Took it home, plugged a hair dryer in and let it run in the big hole for like a half hour or forty five minutes.. Then I took a torch and heated it up all over an watched whatever remaining water there was evaporate. Reinstalled and never had another issue. So how to do this on a Marinette without pulling the tank.. The first thing is how to drain it completely and get all the crap out before you start flushing it with water.. I don't think there is a 3 or 4 inch fitting on the bottom side to remove and drain is there? If you could, then I would get a snake like you use to clean a floor drain and put it in through the top, like at the gas gauge opening..It does come out, doesn't it? Then put the snake in there and just let it rattle around in there and flush it with water, and repeat till nothing else came out. Then just dry the crap out of it. Hair dryer, block heater, what ever I could fit in there to heat it up.. That's my theory.. But you have to get all the gas and crap out and start flushing with water or you'll have a big bang theory on your hands..And face.. And everyone else in the marinas hands and face.. Probably better to pull it.

Rob,
Don’t cut corners on “SAFETY PLEASE”  yours & your families lives are at stake on this one.
That galvanized tank is 37 yr old. Why play Russian Roulette with 5 bullets in the revolvers chamber.

Norm,
I understand and agree. Jeff had told me this early on when I had asked this question prior to me getting prices.
I will go the route of a new tank and remove the old one tomorrow. I might have to stop drinking beer so I can afford all these projects I have to complete.
Thanks,
Rob

I would at least look at Flounder Pounder and other surplus places before having a tank made. The going rate for used tanks is around $4 / gallon.

a friend of mine in louisville ,ky has a alum welding shop he will build that tank for about 400-500 if your going to replace it try just take it out and clean it with nuts and bolts or pea gravel and hot water like collins69s said we used to do that all the time in the junk yard

Most marine insurance companies will refuse to insure a boat with steel tanks that old. My brother in law had to replace his tank on a '77 F-32 Trojan last year before his carrier would renew his policy. Check e-bay. From time to time they have great deals on fuel tanks from boat builders who are either hybernating or out of business. I agree with Doug about Flounder Pounder. I've purchased a few things from them and had very good experiences. p.s. Here's a link to the Coast Guard regulations covering fuel systems: http://law.justia.com/us/cfr/title33/33-2.0.1.8.44.10.html

First any "marine FUEL tank will not have a drain in or near the bottom. You do not want a plug in the bottom of a FUEL tank that can become loose & leak. If you were to sell this boat @ some future time a surveyor would point these out instantly ! Becareful of using truck fuel tanks most have a drain in the bottom & most are steel & will rust & corrode in a damp enviroment .
I know of a couple of companies that make plastic fuel tanks in all sizes & shapes & they are more a fordable than the $$'s you are talking about. Senor moment keeping me from naming them now but I will look them up & post soon.

On another web site where I dispense equally bad advise, I had the nerve to suggest selling some really old gas that had been sitting in the guy's fuel tanks for years. He was going to pay the marina $$$$ to remove; instead, he sold for $$$ to a guy on eBay, and that guy did all the work!
Should have gotten a commission on that deal, but...

Update,
I was able to remove the old tank today. It was very close but I didn't have to cut any of the bracing.Ya
I am planning on having the new tank the same dimensions but I might shorten it a little. I might drop the size to eighty gallons. I also shopped vac the entire engine room, wow all kinds of stuff in there leaves, nuts bolts zip ties a shoe and more. Lol
I will keep you guys posted on my progress.
Thanks,
Rob
