Each time I'm about to start, I find a reason to put it off, but I'm
about ready to start plumbing my gas and brake lines. I haven't had a
lot of practice, so I'm pretty hesitant about the project. Anyway, I
have a fuel tank from an 80's Blazer. The sending unit has four tubes,
and I'm not sure what each is for. Wayne was kind enough to host a
picture for me at:

I would assume that the large tube on the left sends the fuel, so I
would connect it to the electric fuel pump and then to the carburetor.
My guess is that one of the other tubes is a return and one is a vent.
If that's the case, what is the fourth tube for? If one tube is a
return, do I even need it with a carbureted engine?
Can anyone tell me, from left to right, what each of the tubes on the
sending unit are for?
Thanks,
Mark
