I am going to replace the tank on my '72. There are several tanks on the market for less than $100. Has anyone used them and are they OK? Do you need anything besides the sending unit gasket and filler neck gasket?

TIA, Bob

Hi Bob,
When replacing the tank I think I'd also replace the rubber hoses on the right side… supply and return lines, and on the left side…. EEC hoses.
I'm not familiar with $100 gas tanks so I'd be curious to know why they're half the price of a Quanta tank.
I'b be concerned with the quality of the plating on the tank since that's what stops it from getting rusty.
Regards,
Alan

Thanks Alan,
My thoughts exactly! I even saw one on eBay for $71... hopefully someone that has used one will reply. I read an article saying that all tanks were made from a special steel... I cannot remember the name.
I replaced this tank about 10 years ago with a GM tank. It is brand new on the outside and totally corroded on the inside from that wonderful gas they make today! The "sock" is so covered with varnish that the engine cuts out or bogs at 3000rpm! A treatment of Seafoam did not help at all.

Hi Bob,
Gas tanks are typically made from ni-terne steel.
It's an alloy that makes the steel very ductile which enables it to be easily formed into complex shapes.
Again, I think the quality of the plating would be an issue when thinking about longevity.

Hi Bob, the same thing happened to me. I replaced the gas tank in 2008 with a new one from Ecklers, and by 2014 it was ruined. So I replaced it with a Spectra Premium GM33D, made in Canada, and I only put in Ethanol-free gas. It was a perfect fit and so far so good...looks good inside and out.

I looked at the one you posted about on eBay, it looks OK and has the rubber hose connections, but it doesn't give the brand name.
Good luck.

You make a good point regarding the ethanol in our fuel. It holds water and then when it becomes saturated (about .05% water) the water separates out to the bottom. The result, rust in our tanks.

I wonder if a tank liner product would be satisfactory to prevent the rust issue. Or even fix your current rust issue. Seems preventative would be better though.

One of the vendors here may even have a product.

I, too, am looking for a new tank. Did you decide to Ebay it or go with a name brand? I do have a different year, 79. I haven't been able to find many reviews on tanks and I don't want to have to replace it again in a few years.
