Replace fuel pump ????

[Gregory]

1999 R1100RT with about 90K on the clock. Looking for some insights into whether replacing the fuel pump with this many miles on the clock is advisable or if " if it ain't broke don't fix it " posture is advisable. Just looking ahead to a fun and trouble free 2025 riding season. Thanks all. Happy New Year. Gregory

Oilhead fuel pumps seldom go bad unless allowed to sit in deteriorating fuel for too long a period of time. I can offer two data points. My R1150R had 189,000 miles on it when I sold it and I never replaced the fuel pump. On Voni's R1100RS called Big Red I replaced the fuel pump at 392,400 miles. So my advice is to keep riding it regularly so the pump doesn't sit in bad gas. When parked seasonally use Stabil and if you can park it with real gas instead of partial corn squeezin's do so. And at the young age of 90,000 miles don't worry about it.

Not sure if the RT had or does have a charcoal cannister. If it does I'd replace the pump and remove the cannister. Not trying to restart "the great cannister debate" but I would.

Even if a person wishes to remove the canister, why does that relate to replacing the fuel pump. I don't understand the logic here.

 

[fbt80]

The inlet in the fuel pump and filter has been known to clog up with charcoal as well is other orifices' downstream from the canister, instead of guessing how much has been ingested, I'd replace instead, and the filter as well since you'd be in there anyway.

Warning: Chris's language is...colorful
Wish I could find the video where he shows the filter and the pump.

Yes they had canisters; as long as the filter on the inlet side of the pump is intact, it should be fine.
If the pump develops an issue, you'll know it by the way the bike responds, or its fuse will pop.

 

[fbt80]

Don't fix it until it breaks has never worked well for me.

If you are replacing it, just be aware that the one from EME can be crazy loud. Probably worse in a metal tank than in a plastic tank. I am using this one now:

Must agree, when my R1100s alum tank is less than half full I can hear it with earplugs in and riding. Kind of embarrassing when you pull up to the pump. Louder than the running engine.

Anton, let us know how it goes with that pump, and if you find issues. Would be great to put something in there that doesn't scream at you.

Oh hell, I bought one as a spare anyways. Good package deal of a pump, inline OEM filter and strainer and o-ring for basically $100.

QFS pump package arrived super fast, maybe in 3 days. Had a part missing , with a little back and forth they are sending some foam cover for the pump which aids in quieting it I think. The part does indeed look of high quality, especially compared to the industrial appearance of the OEM pump. I'll install it when I'm next into the tank for some reason.

It went into a customer bike a year or two ago. By "using that one now" I meant that it was my current choice. I do need to order a few more; I know I'll need one for an upcoming job and I need to have at least one on hand.

Got it. Nice to hear it has a track record.

Anton, my pump came with a rubber/foam cover for the pump body, should I use that? Have you used that?
