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.
