Fuel Filter- Before or after 044 Pump?

[StreetDragster]

Hi All,

Reading some old threads about the 044 pump, seems some are recommending it is fitted before the filter.

Is this generally right? What is the benefit?

Is it as simple as a new length of pipe tank>pump, and then alter the pressure side to go through the filter, no need for prefilters or anything?

I have the 044 pump, with the Sytec metal filter, with the paper element. Replaced lines to/from the pump.
I know some of the big power people use pumps in series and stuff like that, but i'm only aiming for M400 spec, so i think the 044 is already overkill on its own.

Thanks

Matt

Mine doesn't look like that, its a Sytec one, anodised red with a screw in blue end cap.

Thanks

I think the 044 has a coarse filter built into its inlet, so could use no filter on the inlet and the standard one on the outlet. Would the metal one shown above be a 'coarse' filter? I thought it was simply the same flow as the paper, but with a metal and cleanable insert.

I cleaned my filter out the other week, 25k miles of use and there was nothing in it at all that i could see, certainly no big chunks of metal or whatever.

If the bosch 044 has a coarse filter already inside the inlet why is it necessary to have another coarse filter before the pump ???

Not sure myself, probably belts and braces i imagine, easier to clean the filter than it is to clean the pump, as it doesn't look removable and is inside the pump body.

Can't be that much FOD in the fuel tank surely

I have but at the moment it's got the filter before the pump as per the original setup. It does buzz unfortunately.
