I have read somewhere that an electric fuel pump should be plumbed in
parallel with the mechanical pump. It sounds like you all have plumbed them
in series. Is that right? If that's true it makes for an easier
installation.

Hi Lloyd
In series is correct. The Rotax mechanical pump does not have a known failure modes
where it fails blocking the passage of fuel. Make sure the same holds true
for the electrical pump or else fit a one way bypass valve in parallel to it.
