Thanks

Nice one. Can anyone who has done confirm that this is a straight swap. I.e. No changing of pipes etc?

The filters are replacements for the standard filter housing that comes with the car. The paper ones have been know to fail so I replaced mine with the metal one needs cleaning out every six months

So the second link filters go in the std filter housing that will now be after the pump. The first link shows the high flow filter for before the pump. Does this come with a high flow filter in it and what filter side is it.

Last thing is what fittings size do we need?

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.

according to the link the paper filter is 8 microns and the metal one is 55 microns ( high flow )

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

A friends 3R seems to lose power under hard acceleration or at high speed. He says it starts to cough. Is this likely to be caused by the filter?

If while on boost then prob plug blowing out as might be gapped incorrectly?

Thanks Bondy, I'll tell him to check the gaps. What's the recommended?

Depends on plugs. Check wiki

hi matt
have you fitted your 044 and if so does it buzz ?

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

Bumping this to the top again as still need some help.

The filter housing mentioned above from Daemon Tweaks comes with a 8 micron filter. This is obviously what we need on the std pump side. What size filter should be used as a corse filter.

Also the above filter can be brought with different fixings. What's our std set up union sizes?

Cheers

I wonder if the pipe from the tank needs upgrading too ?

[mgbond]

I did that a few years ago. It can collapse under heat as its route is tight.

Do we know if the above mentioned filters for inside filter will fit our std filter housings?

I'm thinking if just changing filter element for the metal 55 micron one and then fitting a 8 micron filter assembly after pump.

Does this make sense?
