Fuel cutoff valve?

My 1st Gen sits for long periods of time. I thought it would be a good idea to run the gas out of the carb when I know it won't be started for a month or more.

Can anyone recommend a fuel cutoff valve to install between the fuel pump and carb? A simple ball or gate valve would probably work fine. I found some smaller application where the inlet is only 1/4". Noone seems to make one the correct size for what I want to do.

Any help would be appreciated.

Thanks all

Re: Fuel cutoff valve?

running the carb dry isnt a good idea.
why you ask?
the gaskets will shrink and once you let fuel back in itll leak all over the place.

Re: Fuel cutoff valve?

ok, so I guess running the gas out of it is a bad idea. This car is totally stock. Will be using a quadrajet

Re: Fuel cutoff valve?

The only issue with early Q-Jets is the plugs in the two wells areas leak. Extended sitting periods allow the fuel to leak out of the bowl and into the intake manifold. When you allow it to sit for that long time, when you come back to start it, does it require a long cranking time before it fires? If so, that's because the well plugs leak. On the early models, pre 75, the leaking well plugs is almost 100%.
