3/8 sending unit

I believe the model you need is actually for a 68 1/2 with a the 428CJ option. That came with a 3/8" sender, the capacity of the tank and other factors are all compatible with the earlier cars.

I bought a new 3/8 fuel line, gas tank and sending unit from North coast mustang. My sending unit came with 3/8.

What do you do about the fuel pump being 5/16"?

You chuck it in the woods and get a good aftermarket mechanical or electric pump if you are at all serious /forums/images/icons/tongue.gif
