Recommend replacement gas tank for 1969 c10

[Luke87gt]

Hi guys, I have been reading reviews online on replacement gas tanks for my 1969 c10 and boy are the reviews mixed.

I’m wondering if there’s any go to brand that guys here are using?

Also, if I recall, there are some minor differences between 67-70 and 71-72. It would be helpful to understand what those are so I buy the right tank.

I don’t think it’s worth fussing around with cleaning/flushing my existing tank since it’s 56yrs old and the truck has been sitting for years.


Secondly, eventually I will be swapping in my 350 that’s sitting in my garage (truck currently has a 250 i6). Since I plan to replace all the lines and get a new sending unit, does it make sense to replace the lines with 5/16” or step right up to 3/8” now so I don’t have to do it twice later?

Thank you!
