Fuel filter maintenance interval

Ok, I just finished replacing the fuel filter on my '11 990 Adv. I am not an ace mechanic, but I got it done. I know others see it as no big deal, but it was a PIA to me, even working in the comfort of my garage and cold beer!

So, what is a reasonable time interval for preventive replacement? Mine failed at 10,000 miles and I would really hate to have to do it while on a trip.

Definitely has me thinking about SAS, canisterectomy, Rottweiler intake set-up, etc just so I don't have to deal with so many dang hoses, screws, etc while servicing!

Eh?

Over 70 views and no input? At least it's not an oil thread!

The fuel pump filters on my wife's 990SMT also failed at around 10,000 miles. Blame the deteriorated filters on the corn alcohol so prevalent in the midwest. Replace the filters (kind of a pain), have avoided ethanol fuels, and now have 26,000 miles on the bike with no problems.

That being said, I'll probably replace the filters again this summer.

There is no definitive answer

A convenient method would be to inspect every time there is a chance. And this is when changing oil. This would show how often it is needed. I believe every valve checking is a reasonable interval for most. However for some riders that get them too dark, they could replace at every oil check, or for some that find them clear they could go every third oil replacement. I believe larger interval than that it is looking for trouble.
I would suggest you have a replacement oring 60X3 in Viton handy, when removing the fuel filters since there is a large possibility you tear your o-ring when placing back the fuel pump assy.
Cheers.

Wise words.

When refitting the pump is the o ring enought to seal it or is some sort of goo needed ?

On my old Aprilia, it had 95 000 kms on it and no fuel filter was ever changed on it. Granted they run a diffrent set up. It ran perfect when sold. I think I will do my 990 every 20 k kms or so.

Must order another filter from gefr.

I did my first fuel filter change at 30,000k's and it was time! I have a reverse purge fitted from new and I think this helped. I also give the left tank a good swirl out when ever I have it off the bike.

The o-ring should be enough... unles there is some distortion of the hole. I read one occasion but that is really rare.
Cheers.

Been doing mine every 10k miles. Only takes 20 minutes one gas is drained from tank. I always carry a spare set on trips in case of a bad load of gas.

Same interval for me (16,000 km) and on long trips, I to, carry spares as well as the required "O" rings.

I replaced mine at 30k miles, the filters weren't in bad shape, perhaps the previous owner already replaced them once.

Mine absolutely required goo to seal the filter in, and when I posted on here in frustration, it seemed quite common that the gas tanks distort, and goo is required.

I used this:


And it worked well.

Thanks for the replies. Methinks I will target 7-8000 miles for changes (and carry a spare!) 10,000 seems to be pushing it.

For the 2007-2008's the first interval is immediately. These original filters fall apart and cause running problems.

If you only use very good fuel, like from Chevron or Shell here in the NW, then you can do this every other valve adjust, or about 18k miles. If you shop at the kwiki-mart or go to mexico, do it every 9k miles.

Always have a spare filter and o-ring on hand. Gefr has a good kit.
