I believe it's optional for the 914, for more realistic emergency
practice in handling an engine out. :-)
If I did the math right, not always the case, but the pressure head
on a full tank is a significant portion of the max allowable back
pressure Rotax allows in the return line. Hence, definitely no
restrictor.
