Also I hate the noise of the facet LP pump buzzing away.
I believe it was Rob Dorey who had his tank altered to accept the OEM BMW pump into his Marlin Sportster tank. This involved recessing the top of the tank, making a screw collar in aluminium, and a sump in the bottom of the tank to accommodate the depth of the BMW pump.
As far as I know no one else has pulled this off!
I have no idea how his mate made the aluminium screw neck?

Several of us have made a sump and welded it to the bottom of the tank - to eliminate the need for a swirl pot and LP pump. Simply run a HP pump located in the rear.
