First time I've heard of the Dr. Bean thingy. Can anyone point me in the direction so I can find more info please.

Afraid not Nick, symptoms were the usual spluttering to a halt. Bike would turn over but not fire. When I turned the key the usual clicking sound of the pump priming was replaced with a whirring sound. I took the fuel (outlet) line off and turned the key and no fuel came out. Like I say luckily I had a spare one with me and replaced it within half hour.

In hindsight I should've brought it home and sent it to guys at parts for aircraft where I bought it from to see if they could shed any light on why it failed.

Sadly it's somewhere in the Cedar Forest!!

There you are.

20k plus miles on my 40171, no issues. I carry a spare while on long trips.

I'm at about 50,000 miles on my 40171. Still working well at the end of this season.

I think the biggest thing is to check and clean filters. If you install a FACET filter (I don't, I use a cleanable Pingle, or cheap large plastic moto filter) or any other filter on the INLET SIDE, clean or replace it every 10,000 miles when you do a valve check. I think that running the tank dry, (running the pump dry) or starving for gas over a long period of time can do damage.

Remember, these are Airplane pumps, I'm pretty sure they are not designed to run Dry.

The current one in my bike I'll put another 10,000 miles on it and see how it lasts. Then swap in a new one before my next trip out west. That figures out to a whopping $.001 per mile. If I was just running around town all the time. I'd keep it in until it fails, but not when I travel off road. I prefer to swap out parts before they strand me.

The Facet Pump's INLET Fuel source needs to be Filtered to protect the Pump Mechanism from damage.

When I talked with the Facet Engineer,

he suggested a 74 Micron Fuel Filter but Most, if not all Filters, are NOT marked with its filtering capacity.

The problem with most Fuel Filters in Stores are Opaque and Do Not have their Filtration Specs listed.

I found these Glass ones where you can see inside and they have been doing well for years:

Mine let fuel leak thru while sitting, and would flood the engine.

Did a Dr. Bean kit on my stock pump. All better, no rigging some junk into place that doesn't belong. MUCH better!

No contradiction here!

I've used the facet pumps on buggies since the 80's there is a small screen in many of the pumps that I've had clog up.

I used to use thermal epoxy to put a 1" AL heat sink on the big transistor on top and one on each side to help keep them cool. (They need a little ventilation... not a bunch but some.)

I've literally put a hundred thousand miles on them on multiple vehicles.

Had a Carter and i neglected to put a pre filter inline = FAIL. Replaced with facet 40171 w/prefilter. Better pressure ratio and it works great. No fuel hydro locking like the carter/napa. 06' 950 adv/blk

Well, I look at it as a better of two solutions. One works fine for me without having some janky shit rigged up. The other works, but not as it is supposed to, and has to be "customized" into place.

It's all good bud, just teasing.

The eroding points are just one failure mode.
Many stock 950 pumps also seize (the piston corrodes/seizes). Mine failed this way the night before I was planning to swap it out. In some cases, a sharp whack on the pump will free the piston and have it work again (for a limited time, I guess) - which is how I got home that night.
