Okay I started to send this via private message but I'll post a here in case it helps somebody in the future .. The new switching valve has to be bad with ? unplugged it runs fine off the left fuel pump I plugged the weather pack plug back into the brand new Pollock valve, it clicked really loud and shut all fuel pressure off from either tank.. a test light reveals that the polarity is switching on the plug itself via the dash switch.. pretty sure I've got a defective brand new Pollack valve thoughts on this
