The VL pump is a external type. You can mount it anyway you like, just use your common sense.
You could mount it near the fuel tank, fairly low down. Just make sure you use rubber hose rated for EFI use, and good hose clamps. But with this simple setup you may have to keep the tank 1/4 full to stop fuel surge.
Most people would think about upgrading from the 6mm metal pipe to 8mm of some sort.
