Puzzle ZVZE

I started out on the journey from the forest with a full tank of fuel, 12 gallons exactly.

However, the moment I started out, the fuel tank sprung a leak. I travelled at 50 mph until I ran out of fuel exactly 4 hours later.

I know that the car does 25 miles for each gallon.

How much fuel had I lost through the hole?
