1965 fuel pump

Want to run a 65 fuel pump so I don't need to have an inline filter going up the the fuel command center for my fuel injection. Is the outlet a 1/2-20 flared female? I believe my 66 pump is.

I need to adapt the outlet to -06AN

Just curious...will the 65 fuel pump supply enough pressure for the fuel injection?

O'Reilly Auto shows the outlet fitting size as being 1/8-27

The mechanical fuel pump only supplies fuel to the fuel command center which has an electronic fuel pump in it then it goes to the throttle body.

Didn't know that.

Anyways, it appears that the flared outlet on the 65 fuel pump fits into a 1/8-27 tapped hole in the body. Just remove the flared outlet, and put a 1/8-27 to -6AN adapter in its place. You can find the adapter all over the place...Jegs, Summit, eBay, etc.

Thanks, I didn't think to look on autozone or rockauto, didn't think they would list fitting sizes. Now I know!

Also, a lot of the pumps I see come with a brass fitting of some sort. Anyone know what size they are?

More Information for CARTER M4009
Don't know what the size of the brass fitting is, but just remove it and use the 1/8-27 to -6AN adapter in it's place. One less connection that you would have to worry about springing a leak. The fuel pump I saw on Napa had three fittings that the customer could use. There were two of the barbed fittings to attach a rubber hose onto, and there was the flared fitting that you see on the pump in the Rockauto link.

1/8"-27 is the tap size for 1/8" NPT or 1/8" pipe thread. I doubt 1/8" pipe is used on a fuel pump.

1/2"-20 is the straight thread size for the nut used on 5/16" flared tubing.
