I've been wanting to look at the filter on my remote oil tank but have determined in my Ranger it's not visable....I have read where the filter for the tank is on the "bottom" of the tank.....if that's so, I'm going to have to remove my tank and see what's under there.....there is a line going into the top of the tank along with the electrical relay wire (that I"m assuming causes a warning light to flash if the oil in the tank get's low). That line is spliced - something hard in the line between the splices...is that the filter?? Any help would be appreciated!
