When I was at a flea market over the weekend a fellow had a stand for new small engine parts , I was looking at inline fuel filters and two looked the same but one was white and the other red, I asked "whats the difference ?" he said the red one was for without fuel pumps ( gravity feed ) and the other when you had a fuel pump ( pressure side) I started thinking that the fuel filter I installed on the DB wasn't the correct one and that maybe the running problem I was having :wallbanging: Even on the JD 318 it has a fuel pump but the filter is on the suction side , could that be my long cranking problem, wrong filter installed :wallbanging:

I think the ones For the fuel pump have a finer screen than the gravity filters.

:ditto: Right you are.

RED - 150 micron for use on gravity feed.
WHITE - 75 micron for use with fuel pump.
both 1/4" line.

Most of the commercial equipment with either pulse or electrical fuel pumps I have worked on have a fuel filter between the tank and pump just to keep the garbage out of the pump. Many of the gaoline fueled machines also have a second, and finer, filter after the pump. Many of the diesel fueled machines have a fuel/water separator between the fuel pump and injection pump.
