Gas Mileage Issues

Engine has no points it's electric start. gas is 3.38 here i have no emergency brake i have to fix that along with the drums on the front and possibly replace all the small parts on the rear brakes.

I'll have pictures posted of the engine when i get the extra time from other areas of life to do so. I appreciate all the comments i've seen so far.

The exhaust pipe on the back is rusted out badly either i replace the muffler with it or just find a new pipe. It gets very hot and humid where i live and the car is basically boiling outside since i have no car port or garage to store it in. so when i open the hood i can literally feel the heat hit my face. the fuel pump is away from any parts of the engine that could melt it. I've thought about putting a 318 in it but there are none around here and i am not sure if that would even guarantee me decent gas mileage.

The gps idea came up with the estimate i'm getting 8 or 9 miles per gallon. i work minimum wage and this is practically my everyday driver so i need and want it to get some better mileage. I think that answers most questions i hope! i'll be sure to clear some more things if need be but stay tuned for photos! :)
