What is this???
Hello everyone. My great uncle has a 77 corvette. I know very little about these cars and have done minimal work on them. I am also fairly useless on carb'd engines. What is this? Fuel filter? Overflow? It is leaking gas, and before i tear into it i want an idea of what it is. It is the silver circular "pod" in the center of the picture.
Thanks in advance,

Ok that was my original guess, but i was told by some "corvette guy" that the pump was underneath. So i guess the pump is leaking gas. There are two holes in one the upper portion above the seam, one would spray/mist gas out. So i found a small screw that fit and put it in. Now it stoped leaking for some time...... Well the other day i walked into the garage and it smelled of gas agian, so i take a look and start it up and sure enough leaking from the pump. Not the hole but spraying from the top portion that apears to be attached to the block. So i pull it into the shop and put it up on ramps. Start it up and look and no leak at all..... Is there some kind of overflow/overpressure system that causes it to spray/leak gas sometimes and not others?

if I were you I would replace the fuel pump and all the rubber lines that go to it.
The engine compartment is a dangerous place to have a fuel leak, and if you look directly to the left of the FUEL pump, you will see a SPARK plug boot.
FUEL + SPARK = FIRE + fiberglass = uncle's melted Corvette.

This is not a hit and miss situation, you will not get "one more chance" if your great uncles car burns to the ground over a $34.99 (auto zone part# 41240) fuel pump a couple of clamps and $5 worth of fuel hose.
you do the math on this one;
fuel pump and related=40-$50
car burning to the ground=$5,000-$10,000
and the possibility of serious injury.
and by the way, on this forum we find a way to express ourself without cursing.

You need to buy the small hoses from one of the Vette vendors or maybe (long shot) a Chevy dealer. One of the hoses is formed into a tight S-bend and you will never get a piece of regular fuel line to bend without kinking. Also use a metal line up to the carb. It's tempting to just run a rubber hose but that's a bad idea.

A bad fuel pump not only leaks to the outside. It can leak into the engine also. The more you run the car, the more you fill up the engine with fuel. The more fuel in the engine, the thinner the oil gets. Eventually you will burn up the engine. Change the pump. Don't drive that car another foot. Your either going to fry the engine or fry the whole car.

Change the pump.. Here's a caveat though,, think it's called that
I'm not sure when GM changed the feed on the fuel tanks, from the bottom to the top,, but if your tank has the bottom connection for the fuel line, YOU MUST IMMEDIATELY PLUG the 3/8" STEEL LINE FROM THE TANK on removing the 3/8" (larger of the 2) ploy line from it. When i say immediately, i mean in like 1 second, because the tank will try to drain it's entire content on to the floor where ever you are working, if you don't. There are no check valves, or cut-offs between the tank and the carb, if any part is lower then the top of the gas in tank, it will start to drain as soon as the line is released.
