Having had lots of issues on previous vehicles with Facet Matchbox pumps, the one I have had fitted to my GP (with 34 ICTs) for the past 20 years has been completely faultless. Even the clatter it makes has been useful as the noise changes if there's an issue with fuel delivery for whatever reason. I've got a replacement rotary pump and filter ready to go on when the Facet calls time, but that's sat on the shelf for fifteen years. I've changed from being a hater to a fan of the Facet Matchbox!
