Nice job. Since I have yet to move my filter, I'm going to take a look at where you put yours. Maybe do the same. One thing I'm not sure of on yours - can you see the filter to see if it has water in it?
Also as far as locating the filter before the pump, like someone said, with the tank so much higher it's all gravity fed down to the pump so the lift pump really just needs to lift the fuel up to the engine. Same as with the OEM set up.
