This gives the inlet spec. I use that spin on filter....trick piece that works well in a dual intank set-up.

I did a metric to 6AN adapter on mine ,but I don't remember what size the metric thread was.I'm running a 040 Bosch intank,with a 10AN line to a 10AN x 6AN wye and 2-044 Bosch inline pumps with a separate 6AN line to each fuel rail.

Bosch also makes a 420L (which is a myth rating) part number ends in "044" that is used intank or inline. I put two in tank.
