electric fuel pump for Rotax 912 ULSFR
can anyone recommend me a backup electric fuel pump, there are a variety of pumps on Spruce's webpage but it is really difficult for me to choose one,
i am concerned if these backup pumps let the fuel flow while it is off, i am bit confused, some say i need a pressure regulator and/or check valve as well,
thank you

You need a fuel pump that gives no more than 4 psi pressure, then you don't need a gauge or relief valve.
Try and position the aux pump so that it gravity feeds from the tank, eliminates the risk of vapour lock.
Bought my Facet from A Spruce and it feeds through when off.

Evektor fits a Pierburg pump with a check valve, as per page 123 here:
http://www.evektoraircraft.com/files...-2011-comp.pdf
In the UK many 912 ULS powered low "wet" wings homebuilts are fitted with the
40106 FACET SOLID STATE FUEL PUMP or the 60106 FACET POSI-FLOW LIGHTWEIGHT SOLID STATE FUEL PUMP, without a check valve. Vapour return lines are mandatory.
These are the fuel pumps offered by the UK Rotax dealer. Until very recently they were also the local Evektor importers SKYDRIVE :: Products
