He doesn’t now how much they’ll cost and neither does the guy on the phone. They are still in the early stages of reproduction so they can’t determine the costs yet. Since it’s Fusick, I’m guessing that it’ll probably be around $400-$500 since there won’t be any competition.

Ya, that's what I figured. I wonder how much they paid Dorcey for the sacrificial tanks?

Obviously they'll have to cut them open to accurately place baffles, etc.

I assume you're happy with the results or you'd be warning us off.


I suppose the first was 20 years ago. Since I keep spare tanks for all (very
old) cars on a shelf, they get rotated into service about every 1.5 decade. I
have not been keeping accurate track of road time per tank, but so far no
issues.

Since my cars are of the 5.7L diesel era, they mostly get diesel tanks with
several extra gallons to extend range, no restrictor. Cost, cars cost money,
just be sure you get the quality you pay for. Good maintenance has helped
me avoided buying a new car since 1979. good luck, Bruce Roe

Yep. I've never owned a new car or a "modern" car.

It helps to have more than one though, so you always have something to drive while the other(s) are being serviced. (that's my excuse, anyway)

I'm thinking of "repairing" the fuel tank in my garage (finally moved in to a new house that has a garage) by removing the rust with vinegar, neutralizing it with distilled water, and pouring in a sealant. Just a temporary fix until the new tanks from Fusick are available. Has anyone tried this before and is it an effective method? I'm trying to do this on a tight budget and have to do it soon since the rust keeps clogging up my fuel filter (keeps stalling at stoplights from lack of fuel to the carb).

Hi Nic,

I have used vinegar to remove rust and other corrosion from metal for many years. A friend of mine found a really nice Benchmade knife at the bottom of the ocean while scuba diving. He had it displayed with his rock collection as an artifact. It was entirely corroded and crusted up and not usable.

Soaking for several days in vinegar removed all the corrosion. An old toothbrush helped it along. There are only minor pits in the body of the knife and slight discoloration on the blade. He gave it to me after I was finished cleaning it.

I'm currently experiencing the same problem with a 1966 Mustang that hasn't been on the road for 15 years. I got the car running but the inline filter keeps clogging up with globs of rusted metal causing conk outs while driving.

Fortunately you can build an entire Mustang in your back yard with brand new (cheap) parts from a catalog.

A brand new, zinc plated, OEM style gas tank is $79.99. If you want stainless steel, it's only $129.00. That's one advantage of owning a dime a dozen car like a Mustang, Chevelle, Camaro, etc.

I like my one-of-a-kind Toronado a lot better, though.

Okay great, hopefully my tank doesn't have too much rust to the point where holes show up when I use vinegar to clean it, but I doubt it. I'm thinking of putting small rocks inside it as well so it can loosen some dirt and rust that is hard to reach. However, I'm not entirely sure on how to remove the dent from the tank.

The gravel is a good idea. I wouldn't worry about the dent.

FWIW, I recently went through the same issues with the fuel tank on my '66 Toronado. I ended up sandblasting the exterior of my tank. This created some pits in the top of the tank, from which oozed gasoline. My local radiator shop charged $200 to clean the interior of the tank with muratic acid (available at local hardware stores); then dumped the acid and neutralized the tank in his radiator cleaning hot tank (which I assume uses sodium hydroxide); then coated the inside of the tank with "Renu" ( available at O'Reillys's Auto Parts). He had to cut and patch a small hole in one corner of the tank to get the acid, neutralizer, and "Renu" out of the tank.

When I got the tank home I painter the exterior with epoxy primer and enamel paint. So far the repair was a success. The tanks rust on the inside, top of the tank.

My previous experience using muratic acid is that the treated metal immediately starts to rust. I now use a metal prep acid (available at Home Depot) that contains phosphoric acid which I understand dissolves only the rust and not the base metal.

My '66 tank has a baffle in it that would make removal of gravel extremely difficult. Proceed with caution putting something in the tank that you cannot remove in its entirely.

Ah okay, thanks for letting me know! I decided to use vinegar, salt, and baking soda altogether since baking soda has phosphate and the vinegar and salt react very well to remove rust. I might paint the tank as well since it’s already out, but need to find a way to remove the dents. I heard that using an air compressor and sealing the holes helps expand the metal and remove them, but have never tried it. Are there any other methods that could work?
