Some of the pictograms posted earlier in the thread show the filter preceding the pump. This is the case with the new direct injection deisel and gas engines which use injection pressures up into the hundreds of bar so the pumps are extra fussy about dirt and need the filter in front of them and the high pressure would make the filter can too expensive and heavy to position after.
