Anybody know which tanks are interchangeable, and if so, any modifications needed? I'm restoring a '72 MGB, and its gas tank is history.

If I remember right they switched to the bolt-in tank in '75, and never changed 'em again. That said, a tank is something to just buy new. They're not that expensive.
 
Bax, I may be wrong but Tony was talking about boltins in 70, and vented about 73 or 74
 
Fat fingers. Meant '65. And I don't think after that they all interchange. Hadn't thought about venting, which would be something to consider even if it wouldn't necessarily stop the interchange.

Regardless, my advice is buy new. It's not worth hasslin' with.
 
I agree with that Baxter

Yep -- All intentions to buy new. Just making sure, as most body parts are interchangeable, yet there are several tank styles.

Anyone know of oversize tanks on the market?

Why would you want an oversize tank. Everyone knows that these cars were designed to run out of fuel before the oil loss was serious enough to cause problems. A forced oil check & refill.

I just replaced the tank in my 70 B. From what I read, I should have had a vented tank, but mine was unvented. The Carbon canister had been pulled from my car, so even if I wanted to put in vented tank I had nothing to vent to! I checked all the options, such as having my tank fixed ($300 I was quoted!) and complete replacement was the most economical way to go. I couldn't believe how bad the top of my old tank was when I finally got it out. A big rust bucket! Except for a stuck bolt here and there is was relatively an easy job. I did it in a less than 2 hours. If you do decide to do it, I would recommend replacing the sender at the same time. It's $20. I would also recommend getting the fastner kit. Another $9 well spent. Also, rust proof your new tank with POR-15 or something similar and it should last another 30 years!

Fuel, or oil?

I guess I really didn't answer your original question. The vented tank is interchangable with a non-vented if you get a vented gas cap for the non-vented tank. (or you can drill a 1/8" hole in your cap) But if you already have the carbon canister in place, go ahead and get a vented tank.
 
I looked and looked when I replaced my tank...and ended up where I started with MOSS and have been very happy with the Vented tank I bought from them...except it doesn't have a drain plug. That might not be a big deal, but the catalog showed a drain plug and it didn't have one. But it does have baffles and fit like a charm.

I also concur with the advice above to buy the new sending unit, gasket and intallation kit, as well as to prepare the tank and the bottom of the boot with POR15!

Entire job took half a morning and was easy, even for a novice mechanic like me.

Thanks for all the input. The plan is to go with all new, including sending unit. I would like to find an oversize tank, if available, as this will be a "cruiser" as opposed to our TR3. Just would be nice to have a little more range, but not crucial.
