Many thxs for the input---I was thinking maybe I should stick with the cube rather than a rotary type pump which sounds like it would need the bypass plumbing for added safety.Thxs

Hi All,I wonder if anyone can tell me if an electric fuel pump fails ?will it still flow fuel.My setup is in a Wasp with a 912 100hp.Was thinking of putting a facet posi flow or interrupter type back up pump(max press 4psi).The Rotax manual does show a bypass around a booster pump but this complicates the plumbing if its not needed with these pumps (does have a cube facet at present,but its very noisy) Many Thxs
