Default Where to locate spray bar hole? .25LAS

I disassembled my OS .25LAS to get rid of the remote needle valve and replace it with the O.S. Needle Assembly 20-25FP-S. I've attached a photo (I think).

I didn't note the location of the spray bar hole in the venturi, and wanted to see if someone can tell me where to place it.

Thanks,
Frank

Center of the Venturi, where the velocity is the biggest.

If you can't see the hole, the spray bar will work fine. Maximum suction is obtained with the hole at 26 degrees ahead of the line down the center of the venturi. People who race using suction engines have figured this out. For your application (or mine) the first sentence is adequate.
