Spray bar diameter

[Bob Zambelli]

I am setting up a program to calculate the exact venturi area of a standard (through-hole) spray bar, and I need the diameter.

As I recall, it was around .157 but I'm not positive.

Any numbers???

THANKS!!!

Bob
I just used the digital calipers that Bill Gruby gave me and checked some that I have.
Fox 35 spraybar - .125 diameter
OS spraybar - .156 diameter
An old universal replacement spraybar - .120 diameter

Hope this helps,
Clancy
