Clogged Fuel filters

It appears I have the symptoms of a clogged fuel filter. (990R,13k miles) Now for the dumb question. Are there filters in each tank? or only on left side? I did look and could not find answer. I did order two from GEFR on the forum.

Thanks,
Jerry

I thought I was getting a clogged line at times so I did it last month. Pretty easy really with a oil change.

as mentioned, the fuel filters are both attached to the fuel pump on the left tank. when you change the filters, can you cut open your stock filters and take a pic?

here were mine at 10k, when the bike nearly stopped running:

I'll be damned....


like this also the pump will cavitate and burn.....

sorry, but prefilter is the FINAL solution :)

the worst that can happen afterward is soot (pigment much smaller than 0 micron) making all black but perfectly working, injector cleaner and off you go for another 40.000 km

it just started coughing and running like crap yesterday. It sounds like it is for sure the filters. I will change them. Hope the pump did not take too much abuse. Will report back. Also I ordered filters from GEFR awhile ago and the price and delivery time were great.

Cheers and thanks for the feedback.

Jerry

Mine was at 16k. It only did that slow go twice, but having been stuck with a broken bike before,I was not taking any more chances. Mine was darker than the brown one above, but not as black as the center ones. Too much gas from Arkansas's older gas stations in the woods, I guess.

Yesterday I helped a friend change his fuel pump filters on a 990 Adventure. Once done, and everything tested, he left and 5km away his bike stopped. 11pm and stranded on the side of a highway. Not funny. We disassembled everything again and found the black wire inside the pump that connects from top to bottom was loose at the bottom connector. I guess it was loose and since we didn't need to unplug it from that connector (only top one) for the filter change we didn't realize it could be loose.

I'll check those connections on the inside at the bottom of the fuel pump next time I change my fuel filters.

Oh, and by the way, that 61x3 mm viton seal is too big (and a huge PITA) for my bike or his. We used 60x3 and I'm going for 59x3 next time, no doubt.

61x3 in NOT the size :)

original is a 60x3, I prefere the 59,99x2.62 Viton,

have always two, one you put the other you swap and the first one will be fit again in less than a week :)

have fun :) next time put also a plastic Nylon binder on top of the metal clips, they may come lose if not properly in place

Oring OEM size is 60 X 3

You can measure it on the metal groove where it is mounted in the fuel pump housing. However seems even viton gets puffed up from petrol. I believe that help its sealing destination, but could be misleading if measured after being soaked in the tank.
Cheers.
