C3 Gas Tank Info
Hi all, I am new to the forum ,this is my first time posting.
I just bought a 74 vette i live in the northeast and am trying to get on the road before the end of the season. I need a gas tank mine came with an 18 gallon the ones i have seen available are 18 or 24 gallon, the dimensions for the 24 gallon are the same as my 18 gallon. i know mine is 18 gallon because it filled up with 9 two gallon pails of water. Any advise here would be appreciated, i just want to make sure I get the correct one the first time.

When GM adapted the tank to accomodate the non-leaded fuel nozzles, they not only decreased the large tank opening to the small hole for the non-leaded nozzle, but they also extended a tube in the tank tank opening so that it extended an couple of inches into the tank. This prevents the tank from being filled and also creates an air bubble on top of the gas. I suppose in a rear end collision, the collision force that might crush the tank has a less chance of rupturing the tank if it has an air bubble in it. This air bubble decreased tank capacity by two or three gallons. So if your year of C3 has this tank in it you can replace it with a 68,69,70 tank and gain a couple of gallons. (or maybe there's some way to remove the extention tube.)
I thought the early C3 tanks were 20 gallons.
