Wes,
You posted a photo of an M38 crossover tube with dimensions.

I can't seem to find it anywhere.

Can you find it for me?
Thanks!

I do not recall posting one with dimensions on it. I have searched my on line albums and my PC files and I have not found any.

I did the same. I think it was a photo from Aforests yellow crossover tube he had to get help in bending to fit.

I know I've seen it here somewhere but I'll be darned if I can find it.

Very rudimentary stuff. All approximate. Total length, length of larger end, distance from end to valve connection, distance to mounting arm, etc.

Oh well. My fault for not book,marking the thing.

Thanks Wes.

Can someone confirm a couple of threads for me please?

On the M38 crossover tube there is a nut welded on the back side for the carburetor vent line. It has internal pipe threads for the tubing fitting connection. 1/4 or 1/8" NPT?

On the bottom of the tube there is a fitting threaded and soldered into the tube with an L-shaped piece of tubing which sticks into the center of the tube.
Is that 1/8 or 1/4 NPT? The photo below appears to show the threaded portion is smaller in diameter than the 1/4" NPT nipple soldered into the tube for the control valve.

Thanks,
Brian
