was Re: [FlyRotary] Re: To Paul SOme diagnosis thoughts
One final thought.....my aluminum sump tank in
not vented. Seems we discussed this at length when I was building this thing,
and since the overflow is pumped into the sump tank, the fuel might just be
pumped right out of the vent.
Paul, this sounds a LOT like a problem I've
experienced.
My
returns go to the main tanks switched by a solenoid. I used to be able to
create a crossfeed situation where I was drawing from one tank, but
returning to the other. The tank receiving the return became full, and I lost
power down to 2500 rpm or so. I was in the pattern when this occurred, so I
just brought it home. I had fuel coming out of the vent. I've seen this twice
when trying to feed the return to a full tank. Maybe the fuel pressure drops
under these circumstances.
In
my case I've rewired the switches to avoid crossfeed and added a
crossfeed warning light.
Regards,
John
Ed....are you out there? If I recall correctly,
you also have your overflow return going into your sump tank. When your
sump tank is full, have you experienced any problems, and is your sump tank
vented? Thanks in advance for your reply. Paul
