Hallo, my eerste post. I have built and installed an under seat tank. I would like to know if I can do the following: I want to extend the original in tank fuel pump inlet pipe to suck fuel from the under seat tank through an extended hard walled fuel pipe that wont be sucked flat from negative pressure. I plan on  drilling a hole through the side of the original BMW  tank and connect the fuel pump inlet pipe through a bulk head type fuel fitting to my under seat tank bottom fitting. Then I plan to drill another hole through the bottom of the original BMW tank and connect via a bulk head type fuel fitting a sufficiently thick fuel pipe (to allow the fuel to run fast through to the under seat tank while re-fuelling) to the other fitting on my under seat tank. This way I do not need any extra fuel pumps, switches or relays attached to the bike. Will this work??
