Injector pump and governor

I've never seen a fuel bowl flow from the inside out. The whole point of a bowl is so it will collect sediment & water & that you can see all that junk outside the filter.

This is Correct... Plus on the Outside diameter of any filter you have More surface area...
BTW it is possible to plumb some filter housings backwards ... but you should Not leave them that way.
