1966 so in 1966 they had that fuel filter that was metal one line going in with two nipples going out one of them at the center of the filter continued to the carburetor one of them offset to the side had a tiny orifice inside and was connected to a smaller hard line that went back to the tank it's my understanding that it was a vapor line to prevent vapor lock so you had to position that orifice at the 12 position.

Since those filters are nearly impossible to find now with the correct 3/8 in 3/8 out and 5/16 orifice I was curious if I could run a simple brass T fitting and a regular single and single out filter before and or after the fitting?

Ames lists them. PN184A

The T approach would probably not work. The inside of the filter has the 3/8 tube extend a little into the upper outlet chamber to allow for a vapor collector. That's why it should be mounted at 12:00 if you have that mounting. Older applications mounted them true vertical and then it didn't matter.

There are also some with 5/16 5/16 1/4 tubes used in some applications.

The sponsors of this ( Aimes ) has the correct filter.
It's part number N132A.

N132 and PN184A is the SAME GF-98 filter for different cars.
