What is the thread size of the carb. Elbow and sediment bulb at the gas line connection? It seems to be between two sizes on my thread gauge.

That gas line pack nut that goes on the elbow or at the sediment bulb is 1/2" x 18 tpi.

The inlet elbow going into the carb end is 1/8 NPT. Pipe thread.

Thanks I’m missing that in my stuff. I somehow managed to cross thread that on my torpedo shut off this past weekend. I hate doing dumb stuff.

You're welcome.

Me too in that dumb stuff, managed to cross thread the steering pinion yesterday. Was moving fast to get a new nut on the steering wheel and grabbed the dang wrong thread chaser die...duh.... :shock:
