Some time ago I wrote Facet, asking about why my pump was making such noise. The reply was quite interesting, so I thought I would share it, as I know many people here use the their pumps ...
Here's my mail:
I bought this pump 2 years ago, through Rugged Roads, and it's a 40105, as far as I know. The pump rattles and clatters very loudly at random times and intervals. When it's cold, when it's hot, going fast, going slow, full tank, empty tank, there's no pattern as far as I can tell. A LOT of people are having this very same issue, and many choose to change the pump to a different brand, as noises like that certainly doesn't inspire confidence.
I would like to ask if this is common, and why it's making this noise, and finally, if there's anything I can do to make it run more quiet and smooth.
Looking forward to your answer. Many thanks in advance!
Best Regards,
Thomas

Hi Thomas
Thank you for your email and for using our Facet fuel pumps. In many cases the noise is coming from the internal piston hitting against the seat of the outlet fitting. However when the pump is fully primed the piston is protected by the fuel and will not slam into the seat as hard. If this is the case with your application, I can only guess that the fuel pump is losing prime or is not getting enough fuel and some reasons for this are as follows.
1) Low voltage
2) Bad ground
3) Pump is mounted to far from the fuel tank. (40105 should be mounted within 12 inches of the bottom of the tank.
4) Fuel filter is to small preventing fuel flow.
5) Wrong fuel pump for the application. (The 40105 is much too big of a pump for your motorcycle, I would recommend a 40177 which is a 1-2psi pump and is rated for these small engines)
Please let me know if you have any other questions.

You are running the pump at shutoff because it’s to large for your application. The 40105 is rated for 30gph and you only need about 3gph. You are probably over heating the pump.
