The Pinto I have sat for years, I had carb rebuilt and put new fuel pump on and also new filter
I have run a tank of gas out with a can of Sea-foam.
Just tonight the car stalled died like it ran out of gas, but i have almost half tan.
Sat for a min or two fired up and it ran good/normal for about 2 miles then same thing died sputter like out of gas.
fired up again ran about 2 miles again same thing again about 4 times before I got it home
so does the tank ahve a sock/filter in it? that maybe the seaform broke crap loose
