What is the difference between a BB and a SB gas tank?

Some of the part houses only list one, and some list a BB and a SB?

All 59 tanks are the same except for El Camino. 283 & 6-bangers had 5/16" gas line and gas tank sending unit and 348's had 3/8".

so just the sending unit was different.
I am swapping from a 6 cyl to a 348, thats why I asked.

Well, I had not planned on changing the fuel line. Stick with the small 283 sending unit or the 348 unit on the smaller line?

:dealFor what you intend to do with this car,the small line/sending unit will be fine.
