1970 4x4 blazer fuel tank ?

[paul blair]

Looking for a direct replacement 21 gal fuel tank for a 1970 4x4 Blazer. Seems the tanks I found need the filler neck modified. The original filler neck comes out of the tank horizontal, all the ones I see offered angle up. Any one here know where to buy a tank that does not need to be modified?

I don't think they offer a direct replacement best thing to do is remove you filler neck before scrapping the tank.

The filler neck has 2 nuts and is soldered on to the tank...you can melt it off if you have a torch set-up or take it to a radiator shop...you can also get some pre-formed hoses and work it that way. That's what I did on mine.
I cut about an inch off the neck.....got some pre-formed 45º fuel filler hosed and a coupler....I made it come out in the correct place to connect to the filler tube on the body....
2 of these https://www.fillernecksupply.com/1-3...ler-neck-hose/ and a stainless coupling...
you have to route them around in front of the body mount to be in the correct location

here's where it need to come out across the frame.

original tank with neck still on it

Most all the vendors have a similar tank...I try to use vendors that are here on the board...GMCPauls is a good place for parts.

Since you still have your tank...I would suggest just having the filler neck moved to the new one...that's the best way....
