(18-4 step 8): Continuing with the dimpling duties Angela spent a little time deburring and dimpling the ribs.

I
got back on the Fuel Guardian installation. I had heard from a
couple of -10 owners who are using it that when the fuel level gets low
(but not low enough to trigger a warning) and they hit turbulence the
fuel sloshing in the tanks has a tendency to uncover the sensor and
trigger the warning light on the dash. It seemed to me an easy
fix could be a small box surrounding the sensor with a hole in the top
& bottom to allow fuel to enter and escape but not too quickly...
sort of a baffle system. I was a little concerned about metal
being to close to the sensor thus triggering a false alarm (or even
worse, possibly never allowing an alarm) so I contacted the
manufacturer and discussed it. They suggested at least an inch of
clearance and not having the metal normal to the sensor. So, I
took some 0.025 sheet and cut this shape. Nothing real exact...
|
After
bending it to shape here's what I came up with. The flanges at
the bottom are where it will attach to the rib, and I plan to proseal
all the gaps.
|
Here you can see the sensor temporarily installed in the rib, and the size of the 'baffle' box for reference.
|
And here's the 'baffle' box clecoed in place on the rib after
drilling its rivet holes. Its close to the sender mounting
flange, but there's plenty of clearance. On another note, I
originally put a #30 hole in the top and bottom, but after rigging up a
test with a plastic cup using water, that size hole didn't allow the
water to drain completely... that's not good! After messing
around with a few different sizes, I finally decided on a 1/4" hole...
it'll easily allow all the fuel to drain from the box, but not TOO
quickly... that would defeat the whole purpose!
