03 with 190k miles and new injectors. It was leaking fuel out of the water sensor so i replaced that and thought i fixed the problem. Its still losing prime over night though, once you get it primed it will start up and run great all day long, let it sit overnight and same thing again. I found a very small leak on top of the fuel filter housing where some kind of wire plugs into it, would this small leak be enough to make it lose prime overnight? if not where else should i look?
