Terrible fuel economy in my 6cyl Falcon.... tuning questions....

You should be getting at least 18 MPG. No way an engine can use that much fuel, it would not be running it would be way too rich. Has to be a leak.

I know the mustang gas gaps... when they fit loose, everytime you step on the gas from a stop, gas sloshes straight out the tank.


Where is your tank filler pipe? Low and in the back? Loose cap? Worn cap gasket?
