I am finally getting back to working on my brother's 74 Duster that has been living in my garage for the last five years or so.

Anyway, today I discovered that the gas tank has developed a small leak. It hasn't started puddling on the floor, but the bottom of the tank is very wet. This tells me that the tank is slowly rusting out from the inside. Right now the tank is full of five year old gas/varnish plus whatever was in the tank when we got it five years ago, including rust.

I have a kit from Eastwood to clean out and reseal the tank, but I am worried that it won't be enough to seal the leak. What are my options for new gas tanks?

Thanks.

when I decided to clean mine out I found some on the web for $114-140 or so. I didn't save any links, but they are readily available for mid-70 a-bodies. I also found sending units, fuel tube grommets, floats, O-rings, and gas socks. I only bought the grommet, gas sock, and a float, as I was able to clean mine with electrolysis using a caustic soda solution.

forgot to add, I also came across straps and j-bolts, too. it is important to differentiate between the California tanks and the regular ones. cal tanks have a fuel return line (extra hose barb).

Thanks for the info. This tank is dented and it leaks and I am fairly certain it is full of varnish and rust. I am going to just order a new tank from Rockauto. $180 delivered seems like a fine price to me. I would rather not deal with derusting, devarnishing, and then crossing my fingers and hoping that the leak would be sealed. Sometimes new is just better.

New is by far the best. Get the filler grommet and sending unit seal too. Otherwise you're likely to pull the tank to replace the filler grommet.

I understand completely. if the tank was the only thing I needed, it would have been a no-brainer.

my car literally sat for years (and of course, there's a reason it sat to begin with), plus I knew I would have to get tires, battery, etc., so I had to do mine on the cheap. time was not a factor in my case.

New tank and save the sending unit lock ring. The original ones are a little thicker than the new ones that come in the lock ring/seal kit. The original one on my Valiant was bent to hell and the new lock ring didn't seal well enough so I had to make a spacer out of gasket material to go in between the lock ring and sending unit to keep it tight.

I replaced the tank in my '64, for much the same reasons. Make sure you get a new filler grommet and sender gasket. A new sender might be in order, as well. Oh, and straps and liners and that nasty pad that goes on top ...

My tank and sender came from Spectra. The tank works. The sender does not work well - Indicated full is full, indicated empty is 3/4 and 1/2 and 3/8 and ...

Thanks. THe tank is a SPectra tank and supposedly comes with a new sending unit gasket and retaining ring. I will see how the original sending unit works (I think it worked the last time I checked), clean the sock filter on the pickup, and inspect the condition of the insulating pad. I wonder why Chrysler never put plastic gas tanks on their cars like they did on vans? Dodge vans could get 32 gallon plastic gas tanks.

32 Gallons in a 1974 Duster! You could do Wheelies!

Pretty easy...

1) The A-body gas tank has not changed much since 1967 other than some small details (emissions nipples and the single tranverse strap vs. the suspender dual straps)...with literally an unchanged format and buying these by the lot it'd just be cheaper to keep them the way they were and spend the budget elsewhere than retool for a new process.

2) Having been rear-ended and had the jack slip off the center section of the axle just right, the metal tank is much more durable than the plastic one, and given the way Pinto and some of the new cars have had issues with this I'm glad Mopar didn't change this old fashioned item, period (I'll take the dented unleaking can over shattering the tank and having the rear of the car go up in 18 gallons of flaming fuel...)

Interesting. Maybe the Dodge van gas tank was more protected than the passenger cars.

congrats on the new tank! you gonna play w/ the old one? it could be.......FRANKENTANK!

Remember the cars are uni-body...so the A, B, and some C body cars if not prepped (cut and hammered in demo derbies for this particular collision) or rearended a certain way (the rear panels collapse correctly to accordion if it's a 100% end to end collision with a similar weight and bumper height car) tend to "duck tail" in a rear collision...which leaves the gas tank exposed or even worse (crushed and torn), and the impacting vehicle will slide under the rear bumper and impact on the rear leafs and tank.
