Bill,
I couldn't agree with you more. I added mine after the wings were
already closed. Not too difficult to do with fiberglass. I set the
wing so the dihedral was correct, added a clear hose to the fuel supply
line and filled the wing with 7 gallons of water. I made a mark at the
water level and installed the sensor fitting at that mark. I figure
there is 1 gallon unusable fuel, so 6 gallons useable should be about
30+ minutes cruise on my 20B. Oh yes, then I drained the water and
dried out the tank. I put two red LEDs on the panel, one for each tank.

Subject: [FlyRotary] Low fuel sensors (was: Oil level sensor)
I am building the tanks for my RV-7 and I'm also planning to install one
of these in each tank.
Attached is a drawing of a mounting flange I designed.
Perhaps I will modify a stock drain flange instead of making my own
flange from scratch. I need to check with Vans on the price of two extra drain flanges.
When you consider that the second leading cause of GA fatal accidents
is fuel exhaustion, an independent low level sensor and indicator is a
prudent addition to your airplane.

Ernest,
One last possible solution then I'll shut up. Have you considered
using
one of the GEM ELS-1100HT (http://www.gems-sensors.co.uk/) sensors
designed for monitoring liquid levels. They claim these will work in
oil. Suggested uses listed are monitoring radiator levels, machine
tool
oil levels and water reservoir level in food warmers. The HT version
is
good for 100C. I'm using one of these in each wing tank as a 30 minute
low fuel warning (independent from fuel gauges). Pretty simple to hook
up to an LED.
Mark
I'd be interested in hearing other opinions.
