I noticed that there appears to be a piece of metal or fine mesh screen that seems to be sticking up right where the fuel goes to the fuel line or shutoff valve. My tank has a shut off under the tank that will swivel 360. I have a few questions; is there a way to safely get the valve out of the tank without messing it up, is that piece of metal normal? I cannot take a picture of it just because the tank is black so there is no way to get the flash to work and if I try to use a flashlight you cannot get the camera in close enough ..??? on a side note where is a good place to find the wiring diagram for the regulator? I know a bit out of the fuel range but seems to be more and more issues... thanks for any help Pat
