Raimo=0Athe top of the tank is the right place for the return line, as you
suggested. That way hot fuel gets mixed with the whole tank content instead
=C2-of=C2-being drawn straight back to the tank.=0AGraham=0A=0A=0A_____

ect: Europa-List: Fuel Return Line=0A =0A=0AAll,=0A=C2-=0AWe have a fuel
selector valve in fuel line. We try to remember =0Ato close it before a pos
sible emergency landing. Some pilots close it always =0Awhen not flying and
some people close it only during a long storage =0Atime.=0A=C2-=0AThere
is also a fuel return line. That is connected to the =0Atank bottom (starbo
ard side /reserve side) if built as per a BM (issue 6, page =0A6-3). =0A=C2
-=0AI have two guestions:=0A1) would it be wise to have a 2nd fuel valve
in a fuel return =0Aline also to get an ability to close it or one-way-valv
e in the case of =0Aemergency?=0A2) why this line is connected to the fuel
outlet which locates =0Ain the bottom of the tank? Why not to the upper cor
ner of the (reserve side) =0Atank?=0A=C2-=0A=C2-=0ABTW: During this win
ter I changed all the =0Arubber parts under the cowling (oh boy there are r
eally many of them!). I =0Anoticed the fuel restrictor (FS02) was totally b
locked. It was quite hard to =0Aopen it. I assume it has maybe been blocked
since almost new because I had =0Aduring those days (2007) an issue with a
fuel contamination and suffered a scary =0Aengine stoppage because of a to

er and way to use it by selecting =0A=9CRES=9D.=0A=C2-=0ASo,
I have noticed no problems to use my engine with return =0Aline which is of
f-line. There are also many Rotax aplications with no plans for =0Areturn l
ines in use. What is a main reason we should have a fuel return line? To
=0Aget more fresh cool fuel or what?=0A=C2-=0A=C2-=0ACheers, Raimo=0AOH
