Topic: 1970 Mach 1 gas tank

[70Twister]

Need to know if the factory gas tank had a drain plug or not in my 1970 Mach 1 Dearborn with Oct. build date!
And best place to get the new gas tank that I need!

[J_Speegle]

no drain plug by that date

Adding to this, who makes the most accurate gas tank for a 1970?

Same gas tank used in  70 Mach 1, and Boss 2's,  correct? (Excluding California cars)

Not sure - haven't purchased one for a while. Hopefully someone with recent experience will provide some good info for you

Yes all non - Calif emission tanks would have been the same

mine is a 70 scj R code, build date 10-26-1969 Dearborn, has a drainplug, have the original tank, NOS is most accurate have seen on EBay if you got the money

Interesting - What is the date on the tank?

i will take a look first chance i get, its not on the car, too much risk with it being so old and cruddy inside, is it stamp in a certain spot, my tank does have a drain plug, i misspoke

i think you'll find most NOS ones have a different welding pattern than  assembly line. The American Designer repops are actually very nice but lack the original niterne finish. If anyone knows ofc a NOS no drain plug for sale let me know

Tim,

I did end up locating a NOS tank for my 70 B2, and everything I have looked at so far, ribs,  shapes, dimensions etc. look exactly like my original.

You mentioned that the welding pattern  is different between the two. I need to scrape undercoating/paint off of my original to see the weld, but can you please elaborate on what the difference is?

Thanks,
Tony

On an original the welds cross over each other at the corners. The service pieces are a continous weld that round the corners

I want to correct my earlier statement as well. The originals were terne finish, not ni-terne. The newer repops are ni-terne which is terne (lead/tin) with nickel added

Thank Tim. That  was helpful.

Tim,

I pulled out a picture of a 69 Mach 1 Survivor that I sold this past summer,  and I see what you are talking about as far as the weld. I never noticed that weld detail. Even though this is a 69 and the tank is slightly different, I attached the picture as a reference to others and you can see the crossed welds at the far corners.

Thanks,
Tony
