I was going to change my primary filter to the glass bowl with metal bottom type so water or other is visible and then I realized that the current primary filter is the one that has the 12 v. electric attachment that lights up my fuel filter light on the dash. Seems like it would be a shame to get rid of that by replacing it with one that doesn't give you a heads-up. I realize the glass bowl should act as the same thing essentially but you have to look at it instead of be tipped off . If I decide to keep the current set-up, does anyone know where you can get a filter that has the electric hook-up? And those of you who have switched to the glass bowl or another, what was your thinking behind that? (besides cost--how much is it??). Thanks.
