Hi,
I've got a 70 C10 pretty much all original. It has the original 350 V8 and a TH350 trans.
I'm doing a tune up and noticed a metal can in the vacuum line from the carb to the distributer vac can. It has another vac line and a wire going to it. I have no idea what the purpose of this is but it does look factory. I'm probably going to not use it and go a straight hose carb to dist.
The reason I think it is factory is there is a prebent metal line from the carb to the box with hose connecter's.
Thanks for any ideas.
Jon
