Fuel Tank Pics Please!

Anybody have a pic of the top of a LS1 fuel tank with everything installed (99-02)? I'm interested in Hose routing, and are there 3 lines coming off the LS1 pump? I thought return was internal on the LS1's pump - What's the third line?

Thanks
Brandon

Drivers side is supply,
Pass is return,
Middle is vent.

Return line comes from in front of the fuel filter, back to sender, which has the regulator internally.

Thanks, yeah, that kinda helps still confused though?

So the return is not internal? Where does it come from then? The only two lines that go to the engine (+99) are supply and EVAP. And the 99 - 02's don't use the 'vette style FPR, so what returns the fuel to the tank in the return line?

Thanks,
Brandon
