In the fuel tank.
I have an '86 G-20 van, it has a 33 gallon tank
I don't know the exact fuel capacity for a 1984 model Chevy. However, the standard tank capacity for a 1995 Chevrolet G20is 22 US Gallons, or 83 Litres.
5200lbs.
Carefully. Why would you bother?
12 mpg
standard was 22 but Chevy had an optional 33 gallon tank
Mine takes 7 qts. of 10 w 30
Figures from NHTSA crash testing list the 1987 Chevy G20 at 5456lbs, this should be close to the figure for the 86 model.
You need to lower the fuel tank to get at it.
In the gas tank. You need to take the tank down since it's on the top of the tank.
the g20 should be a 350 and I believe the caprice is a 305 you can swap the engines but you will also probably have to swap the intake and exhaust manifolds
