i was reading the how to get rust out thread.. made me think.. how big is my tank. i did some research on new tanks for my 1971 el camino. they are saying the new tanks are 20 gallons. now, my fuel gauge reads just above a quarter tank after fill up. (bad sending unit right?????). the most i have ever put in this car is 13 gallons and that is when it is below the empty line.... i was trying to find stock specs on my fuel tank size.. is it 20 gallons like the repro? i measured mine and it comes close to what they have listed. If this thread fails i am going to go out and drive my car till it dies. then pour in a gallon and fill er up... i kinda don't want to do that so if you know the specs on a stock fuel tank for a 71 el camino please let me know. thanks.

I had a 1970 SS 454 El Camino................black LS6

I do remember putting a LOT of gas in it but not the number of gallons at one time. Gas was cheap (40 cents a gallon) and the big 454 450 horse engine drank it up.

When you drop the tank to replace the sending unit......fill it up with water then.........to get a number on the gallons held.

Fill it up and then siphon it out into a 5 gallon container . . . 5 gallons at a time.

Or just fill it from a known quantity that is indoubtably larger than the tank. Once your tank is full measure how much from the original quantity is left.
