What size threads are on the fuel pump side of the gas line? Some dummy crimped up the line near the carb, and the accelerator pump is leaking. I'm going with an Edelbrock and it has a nipple for a soft line, I want to add a visible filter and braided line, just need the threads. (still driving it.) This does have the dual tanks with the electric pump. I'm not sure what the line plugs into from the carb yet. Any better ideas?

 

You are going to keep the return line orifice piece at the carb correct? Is that where you need to know the thread size?

If so, I am not there looking at it, but if the female threads have a tapered seat down in the middle, then that's a straight thread, and what you should do is go to the store and buy a short universal fuel/brake line, cut the line off very short, thread it into the piece, and that will leave you a short stubby metal line sticking out that you can put the rubber hose on with a clamp to go to your filter.
