ive added an extra fuel filter to the low pressure gravity feed side of the fuel pump .
hopefully this will dramaticly reduce any contamination reaching the (teabag) filter on the fuel pump pick up.especially if you run to tank level low regularly.
the filter is just from my local bike parts guy(any inline bike type fuel filter that fits the hose (6mm)would be suitable tho i would use a clear filter so it can be easily checked )
it only cost £1+ £1 for the hose clamps i will use came from halfords a general motor spares shop who also sell a suitable filter to.

(this is not the finished hose its just to show the hose as i will fit the filter nearer to the back of the tank rather than the fuel pump as in the picture and fit hose clamps to all ends)

Great idea Seth - i did look at the high pressure filter option but if you stop it getting to the pump in the first place happy days ! and with the new teabag you sent me it should cut the crap :smile2:
Very good idea Seth!
But do not put too tight filter to vacuum side of the pump, to prevent cavitation.
Older Mercedes diesels are using just good pre-filters.
I think I´ll copy your idea.
Is this the sort of filter you fitted Seth?

@seth
anything like those would be just fine barmy well found :onya:
they wont restrict the flow in any way.
you can get cleanable filters to but you need to take them apart to see if anything is clogging them.

Thanks Seth..
Can you tell me what internal diameter the fuel hose is under the tank.. The one that the added filter fits in to..
Motorcycle filters on eBay are 6mm and 8mm
Thanks in advance.
Hiya a 6mm one is what you need clear if possible as then its easier to check.
Remember to get hose clamps so the hose can't come off the filter.
:cheers:

Thanks again Seth..
@Villiam3rd This is the thread for the external low pressure filter mod
Seth :cheers:
Hi guys, I have the tank off for another job I'm doing on the GSX and would like to fit an extra filter as outlined above. Just a couple of stupid questions really, on the low pressure side, is the flow indicated as in the picture? and the other stupid question, why does the line come out of the tank and then into the pump, surely it could take a low pressure feed for the pump inside the tank?
Thanks

My guess would be that the fuel is being drawn from the lowest part of the tank?
Yes it looks that way, not much sense in the manual about it, just trying to make sure
It's also drawing from the rear of the tank. So when you accelerate the fuel sloshes backwards, then squirts down that pipe into the swirl pot. Meaning that even on low fuel it should run properly until the tank is almost empty.
The fuel pump takes it's fuel from the rear of the tank.
Goes through the teabag filter then into the pump and high pressure system
Excess fuel is returned to the tank.
The pump only ever takes it's fuel from the rear of the tank .
The extra filter is to help the teabag filter .
The extra filter goes into the line between the rear of the tank and the fuel pump that line is gravity fed only .
:cheers:
OK thanks guys, job done. Teabag filter cleaned out, new inline filter added.
looks great
Fit and forget mostly giving a check when the tanks of yo change plugs in a service or the likes .

+++++++++++++++++++++++++++++++
that small filter has 6mm on the outside but the inlet to the tank is 6mm on the inside.
It has never caused a lack of flow by stretching the accelerator??
That hose on mine, recently replaced, 8mm I.D.

@seth
The 2nd kind as they are more robust and readily available aot a very low cost .
In advertisement plastic filter eBay seems to indicate that it is detachable interior.
Must be different size hoses? Mine is 8mm. This is original hose, now replaced, 6&8 mm filters shown.
I think the important is original I.DIAM of 6mm. so as not to decrease fuel flow
As posted, my i.d of hose is 8mm. Thats why i bought 8mm(5/16 inch) filter.
I"ve finally changed to this filter, located in Germany web with I.D5 and E.D8mm.
Taking into account that the ID of the tank outputs are 6mm, with grease in drills I went to 5.5 and then 6mm without any problem.
This is only a decrease of 0.5mm wall

Just remember the low pressure extra fuel line is just to keep fort from teabag and just helps any dirt be seen and the fuelpump can still get fuelfrom the sump my extra filter mod just helps bit keeping crap out of the teabag
This doesn't affect the main. Fuelpump in anyway
INternal filter perhaps common with other suzys
