You make a good point re the potential drain problem through a cap vent
in the event of an accident.
On the other hand, I originally had the tanks vented on the sides, under
the rear door sills (per plans). Having the vents in this location
prevented me from filling up the fuel tanks, as, when I got to filling
within a inch or so from the top of the cap, fuel would start draining
out of the vent.
I since went to fuel cap vents and am now able to put at least 4 to 6
gallons more per side when filling up. I value this extra fuel safety
margin more than the issue/potential problem with the fuel vent caps.

Basically, Wayne said it all here. I would emphasize, though, the
importance of routing your lines to the centre before going through the
forward part of the fuselage. If they are on the sides under the door s
ills, you risk fuel line rupture in the not so unlikely event of a gear
failure during a taildragger landing mishap. The other good thing with
sealed caps, is that you won't get fuel spillage out of your low win g
tank cap vent, when the fuel flows across the vent tube from the high
tank. And don't ask how I know this.
And the tanks do not feed evenly all the time, at least mine don't.
Also, with them on Both when parked, the tanks will even out nicely
in a short time. I do a lot of partial fuel ups, and usually just fil l
one tank then, because I know they will balance out by themselves if
I have both open. Most of my flying then is with both. It is only on
longer trips, and I'm low on one, that I may shut one side down for a
while.

Sounds "doable". However I am hesitant of low point drains afte
r
the valve.
In taildragger position there is no way you'll get the line lower
in front
of the valve and if you select fuel off while sitting the water
(if you ever
find any) will collect behind the valve..you'll drain clean and
get it turn
valve on and have a problem. Older Cessna valves had a plug in the
bottomthat can have a quick drain installed for a low point.
I like to bring the lines down the Fus-24's and then angle across
the floor
(inside it) towards the center and then head forward and into your
LEFT/RIGHT/BOTH valve. This way your low point will be about mid
point in
the angled section of the line if you postion it right and you are
quaranteed to get the H20/crap out on both wheels and floats. You
lay out
after your valve is how I do it. Hole right thru the
carrythroughs, along
the 5/8 tube..under the pedal shaft..then to the left and up
into the
gascolator. Always leave your fuel valves on both if sitting on
level ground
and this lets the rear drains look after the line all the way from th
e
gascolator back to the low point...since there is no way around
a
rise in
the line to the gascolator when plumbing this way.
