Thanks to the list for all of the good comments about aux fuel pumps in the
701 fuel system One thing that caused some confusion is that I left out
the decimal points in the specs for the facet 40105 pump, which puts out
25 to 45PSI (thats 2point5 to 4point5 PSI)
| Quote: | From the listers comments, it sounds like a 40105 in series with the rotax
mechanical pump will not impede the fuel flow when the facet pump is off
|
So the system really would not know the facet pump is there when it was
off Also it sounds like it would be better to have the in line fuel
filter downstream of the facet pump rather than upstream
A couple of other things I am wondering about One lister suggested that
the facet pump should be installed upstream of the gascolator and the fuel
filter Is this how most have done it? This route would, I assume, have a
T connection from the wing tank lines, then the facet pump, then the
gascolator, then the inline fuel filter, then on to the mechanical pump on
the rotax Also, for those with an aux electric pump, does this help the
problem of uneven tank drainage that some have reported with the 701?
Would running an aux electric pump pull fuel from both tanks more evenly?
I am also wondering about the fact that there is no fuel filter screen in
the ZAC gascolator If you have an inline fuel filter downstream from the
gascolator would a screen in the gascolator just be overkill? Or is it
worth upgrading to a gascolator with a filter screen?
