 |
|
Guys
I have been flying my 701/912s for a while now and after seeing the climb angles possible am considering a backup electric pump to the engine driven one. If it should fail in a max angle climb gravity feed doesn't appear likely considering the fact that the engine driven pump is mounted on the front of the engine-likely above the tank level in this steep climb angle.
Several questions...seems like I remember a Rotax service bulletin a while back concerning engines with electric pumps...anybody know what that was all about? Also is the engine driven pump pervious when failed? It would seem likely.What pressure output pump is correct? I am thinking the standard 5 or so psi pump...
Any other info appreciated
Thanks Joe

Joe. the rotax manual gives max allowable pressure. From memory I think 5 psi is around the top end. Someone else will know it. Based on info I got from this list when I was at this point, I have a Facet PP. from ASSCO. The engine driven PP will pass fuel through if failed. Also, the PP can be inserted in line........Geoff
