1973 vw beetle
Volkswagens are known for their comparably high gasoline mileage. I don't know much about their mileage these days, but the classic Volkswagen Beetle and Camper of the '60s used to get an average of 30 mpg.
Volkswagen always said 25mpg
The 2014 Volkswagen Beetle is a gas-powered vehicle.
The 2012 Volkswagen Beetle is a gas-powered vehicle.
On my 73 super beetle it is about 2100.Yours should be pretty close to that.
14.5 gal
if it has a low mileage it can be a little expensive. i saw a add of a 1977 VW beetle with sunroof for about $15,000 it only has 512 in it's original mileage. to know more you can check some car classifieds on the internet.
As long as the 73 isn't a super beetle then yes they should fit.
25 MPG
I owned a 71 SuperBug and the highway gas mileage was 28-32.
