I'm cleaning up a 1991 rv4 fixed pitch w io320 that's been sitting, builder elected to install a totalizer but no fuel quantity gages. Not sure I like this set up, I would still like to have gages....any thoughts....do others have this set up?
Thanks. Tom
Well, I would want gauges as well, even though they may not be the best. My RV-6 gauges are not very accurate.
Then there's this in your ops limits:
“After completion of phase I flight testing, unless appropriately equipped for night and/or instrument flight in accordance with § 91.205, this aircraft is to be operated under VFR, day only.”
And this:
FAR 91.205 (b) (9) Fuel gauge indicating the quantity of fuel in each tank.
After reading all the above posts, it sounds to me like it the gauges that are often inaccurate, not the senders? Is this correct? I believe the senders I got from from Vans are made by Stewart. Can I assume that my Stewart senders, connected to the EFIS will function reliably?

Don't discount the float senders, I've found them to be accurate throughout the range once three or four gallons have been burned from a topped tank. The key is to calibrate the electronic gauge (or EMS) from the bottom up. Begin with an empty tank and continue the calibration until full.
The EI gauge I use with the floats is very close to what the totalizer calculates as long as I am careful with inputting data into the fuel computer (Trio Pro Pilot).
