Dan,
I know that the emotions about the electrical fuel pumps are great.
Parallel, or in series, this is the point where the opinions are divided. I
let the pumps work in series as ROTAX laid down in the latest Maintenance-
and Operators-Manual, as this version seems to me the only logical design
when flying at high altitudes. If you look at the different ROTAX manuals
(Operators-, Installation-, Maintenance-Manual) you will see in every book
another idea. (Installation-M, page 48 dated 10.5.96 the pumps are operating
in PARALLEL, acc. Maintenance-M, page 32 dated 1.2.97 and acc. Operators-M,
page 9-2 dated 1/98 in SERIES). The documentation of ROTAX is disastrous!
I'm suprised that the Authorities accept this different and not up-to-date
manuals.
Greetings,
Gottfried

Betreff: Europa-List: RE: 914 Fuel System
Hi Dan,
The difference is that in the tech talk, just as in the latest issue of the
XS 914 engine manual the pumps are operating in serial. This seems to be a
Rotax requirement. I intend to follow that requirement, although at this
time i can't figure out where the advantage is. Anybody with more insight?
Kind Regards,
Jos Okhuijsen
