I have a 1989 Jeep Wrangler, 4 banger, TBI. It has sat for over a year with the same fuel, no treatment. It had close to a full tank, now about 1/4 tank. It had good spark before it sat. No start. Charged battery, and added seafoam treatment to tank. I think it would do more in fuel lines, and injectors. How do I add to the rest of the system for best results?
