68" 3-bladed Woodcomp with a 912ULS... also gives you more ground

Thanks Les,
Running the lines forward looks appealing. Do you have any pictures? How do
you protect the lines where they pass through the glare shield - just the SS
braid?
BTW: if you ever come out to fly the canyons in southern Utah feel free to
drop by and visit me in Northern Utah at 36U in Heber, UT.

Craig,
My kit came with 4 tanks (40 Gal) and I did not like the idea of routing the
fuel lines and gascolator behind the seat where I would not be able to
detect leaks.
I am pleased with my installation. I ran the lines from the tanks to the
forward wing root on each side where I put selector valve with inside tank,
outside tank, and off positions. From their I ran the stainless mesh covered
fuel lines down and forward to the fire wall along the steel frame at the
sides of the windshield. I placed the gascolator forward of the firewall on
the bottom-most part of the firewall away from the exhaust system. I was
concerned about potential vapor lock, but a week of flying in 100+ degree
weather in Death Valley and Nevada & Arizona high desert dispelled this
concern.
If I has only a single tank in each wing I would use the same setup with an
on-off selector switch on each wing root. Simple and safe.
Les

Subject: Zenith701801-List: 701 fuel system design
<craig@craigandjean.com>
I've seen a number of different fuel system designs on 701s. My big worries
are the placement of the fuel valve(s) and the gascolator. I want the
capability to select left, right or both to be able to control uneven flow.
Normally I would fly with "both" but switch to left or right if one tank was
draining faster. I'd also prefer the gascolator(s) to be where the Zenith
plans call for them (behind seats) as I'd like a gascolator to be at the
actual low point in the system. I know that some builders place their
gascolators on the firewall as a localized low point. But with the
gascolator forward I just don't see how you will ever get water or junk out
of the other low points in the system.
I'd like a "real" gascolator but placed where the plans call for the Zenith
"box". But it is tricky to mount a conventional gascolator there such that
you can drain it and open it for cleaning,
Places I have seen valves with pros and cons:
- Zenith design with off/on valve on floor by flap handle. Pros: single
gascolator behind seats, don't need access to valve during flight. Cons: no
"both" position.
- behind copilot's head towards the top off the outside wall. Pros: short
runs on lines from individual tanks, single "down" line to a single
gascolator. Cons: awkward to reach.
- centered on crossbar behind and above pilot and copilot just below roof.
Pros and cons are like above.
- on floor near flap handle. Pros better (but not great) access. I've got
chunky thighs and reaching (let alone seeing) the valve is hard. Not an
issue with an off/on valve but more important with a left-both-right valve.
Cons: two gascolators behind seats.
- on panel. Pros: good access to, and visibility of valve handle. Cons:
probably need actual valve on firewall with extension to panel.
One interesting idea I saw (N701RR?) is to not run the line(s) down, behind
the seats and then forward. Instead run them forward from the wing roots and
then down the diagonal steel tubes to the glare shield and firewall.
How have others thought this through?

Craig,
I used a single gascolator but my kit came with two. Find out what Zenith
charges (it's just a sealed aluminum box with a few threaded openings and
couldn't be very expensive) and I will give it to you for half their price.
Never used, but no warrantee.

Does anyone have one they are not planning on using? I know I can buy one
from Zenith but I figure I can get a surplus one from another builder for
less. Let me know a price.

I have four of the Zenith Gascolators from my project. Four tanks, and I
used a different fuel filter/gascolater system. Any one wants anywhere from
one to four they can have em for the postage. Or I'll bring em to Oshkosh
if anyone can wait that long.
