Empty fuel tank weight?

[69427]

Anybody have an early C3 tank sitting around that could give me a weight?

Thanks.

I'll do my '78 (late C3) when I get home from work.
Different size and liner - but you'll have another data point.

i didnt weigh mine when i had it out but it was surprisingly light so dont be surprised by the 14-20 lbs range

WOW! A Day late - and OVERWEIGHT!

31.5 #s for the C3 tank (78 vintage). No internal sensor/pump - but did include a couple of bulkhead fittings for feed/return line -- a few ounces at best.

Anyone know why the huge weight change?? the bladder?? or capacity??

18 gallons for the early tank....what for the later?? seems like a lot....

I would imagine the bladder does weigh quite a bit.

I thought it was just rubber, I can see maybe 6-7 lbs at most there...wonder if the tank is larger? or did they up the gauge of the metal?? I was shocked when I bought a new radiator support for my '72, as the new one was considerably lighter than the old rotten OEM one, which I thought was odd, but found the metal was thinner...

The 16 pound weight is what I'd guess for a 68-70 tank. They don't weigh much. Somewhere after 70, a steel shield was placed over the top and back side of the tank. It was held on with the tank straps.

1977 tank 17.0 Gallons.
1978 = 24 gallons + Bladder. ( http://www.corvetteactioncenter.com/specs/c3/1977/77specs.html )

Also, explains why it fills in the entire back section of the chassis between the front and rear cross members.
Someone will have to do the maths.
