balances the regulator in the pump. The Perry pump is primarily marketed
for surface use and the instructions are written with that in mind. If
the vent faces down in a surface application it is less likely to fill with
dirt and cause the regualator in the pump to malfunction. In an aircraft
application, you still want the vent to remian free of obstruction at all
times, but it is unlikely to stop up with dirt, so orientation
is not as important.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

In a regulator arrangement like Kline, it is critical since the carb draws fuel
from the regulator, but not in the pumped setup. That being said, mine
have generally been placed close to the engine. I did have one setup with
the pump behind the firewall. It had 6 inches or so of fuel
line between the pump and carb and operated just like any other setup I
used. Some people use/experiment with a bypass arrangement wihich allows
the excess pumped fuel to return the tank and the bypass tee for this needs to
be very close to the carb. We never had much luck with this
setup though. It worked, but was a hassle and did not seem to offer
any advantage over the straight pumped arrangement.<o:p></o:p></span></font></p>
