I noticed that my mechanical fuel pump has three lines coming out of it, one for fuel in from the tank, one going to the carb and the return. My return line has a bolt in it blocking it off, right out of the pump.

How bad is this and why would someone do this?

to me, thats pretty dumb

if the carb has enough fuel, the pump wil still be pumping fuel, so there must be a bypass, or else it will force the fuel into the carb and it will flood.

thats what i think about it.

get rid of the bolt and make it as it should be.

sounds like the previous owner didnt know what to do with it.

Not many camaros came with the return line back to the tank. I think only some air conditioned cars. If your car has the line, hook it up. If not, the pump return line can be plugged.
Factory typ pumps with the return line on them are low perf pumps and not up to providing enough fuel volume for high performance.
