Raid Designs Vacuum Fuel Pump Kit

I'm doing some pre-summer preventive work on the 950 Adventure at the moment prior to a trip to Scandinavia. I have decided to change the fuel pump as it hasn't been touched before from what I can see and am
looking at this vacuump pump kit:

Does anyone have any experience using it or a similar design?

Facet 40171

I run the Facet 40171. It's a solid solution.

I had a Mikuni DFS21 Vac pump. It was okay but I had issues with Hydro Lock. Im running a Stock pump with a Dr Beans Kit and its great.

I will certainly consider this as I have just found a supplier here in England. I had heard a few comments of the Facet pump failing too so what does it have over the original one - I know I'm being lazy by not trawling through all the previous threads!
I was thinking the vacuum pump spare diaphragm was an easy spare to carry and install on the roadside.

Thanks for this idea too. I'm just trying to find out the cost and availibility before I decide which way to go.

The Facet is pretty darn solid. I think all fuel pumps will fail eventually. I've found the Facet to be a pretty foolproof solution. It's also very easy to carry a spare in case the original fails while out on the trail. I've run my Facet for 10,000 miles, and I'll get around to buying that spare someday.

Hello there I have a mikuni DF52-21-D fuel pump which I have mounted behind the airbox so its nice and easy to get to, you have to do a bit of plumbing but it works great and the repair kit is tiny plus there is no electic involved and they use these pumps on light aircraft so id say they are reliable, Ive got a load of photos of the install but i cant seem to load them on here if you pm me your address ill sent them you , or im in the midlands in uk so if you are near i will show you

I ran the stock pump for about 40k km and change it as everyone said it was going to fail. Put in a facet and it lasted 5k and quit. A little over 5 k on my second facet and thinking a vacuum pump is going on this season.
I've been riding snowmobiles that use them for almost 40 years and have never had one fail.

I guess it happens from time to time?

I have not had a single issue in 10k miles.

is th pump above or below the fuel level at the lowest ??

you are rinsking a ropture of the petrol film when the level is below the pump thus killing the engine due to fuel starvation :)

we tried such a design with mikuni SV 650 pumps but at high rpm or when in need of real power on the 950adv the pump fuel flow was too low

have you had any of these probelm on your bike?

did you mount any filter before the pump?

thank you for the info

In reply to gogglemonster post the pump is above the fuel level as its behind the airbox, I dont know what the second sentance means as it seems to be not written in english,the pump will deliver 35litres an hour which is more than the adv needs it will only starve it if the vacumn source is to weak so you have to be sure to get a good one( lots of threads on here about that) I have had no problems atall with the pump and a fuel filter always go in front of a fuel pump and I have fitted a fuel check valve after the pump as well to stop any potential hydro locking problems hope that helps.

I really like the facet pump. CJ's kit is well designed and tested
