I'm trying to avoid having to seal the tanks and fill them (per the instructions) in order to get a sensor location.  Does anyone have accurate locating dimensions for the sensors on the inboard rib and the corresponding fuel quantity they show.

   

  Thanks in advance!

We must be in the same spot.  I was looking for the same thing and found photo's on Chris Johnston's web page.  I didn't see how he arrived at his location.  He talks about it under "Tanks - Final assembly" and states the position he has will alarm at 5.5gallons.  Link to his site is below.

Here is a picture of my location.  I filled the tanks up with 5 gallons to get this location.  I am pretty happy with this.  Because of the fuel sloshing in the tanks though they start to come on if there is roughly 10 gallons in the tank.  The other day I landed and both lights were on when I landed.  If I reset it, they will stay off until you hit a little bit of turbulence.  When I filled the tanks,  they only took 40 gallons which meant I had 20 gallons in each tank.  

   

  I trust my fuel totalizer the most but the fuel guardians are there to remind you if you forgot to switch tanks or if you have a leak all of a sudden like Tim did when his fuel drain got stuck.  

   

  Hope that helps.

Hehe.  I copied Scott.  He did all the legwork getting the tank in the right position (dihedral and all that) and found an appropriate spot.  I did some rough calculations (very rough) and agreed with the location he used.  The tank stiffener bead kind of dictates where you have to put it anyway - you could put it lower to have it indicate low fuel at a spot even less than around 5.5 gallons, but having it go on just to let you know why the prop just stopped turning doesn’t seem that helpful!  J  

   

On a side note, you’ll all be happy to know that now I have enough room to finish building my aircraft.  Over the weekend, we “clearanced” the rear wall of the garage, and butted a Rubbermaid tool shed up against the back wall.  Got us an extra 10.5 feet, and some breathing room.  as it was, the garage was about 18 feet long, and for those of you at that stage, the fuselage with the tailcone attached and no engine on the front is about that long (give or take a foot or so).  The garage isn’t that wide either, and with the wings also in there, it’s been tight.  Can’t wait to move the wings out of there and into the livingroom!

Scott, that's exactly what I'm looking for, thanks!  Anyone else with a different configuration?

   

  Thanks for including the additional info about the sloshing as well.  It got me wondering if a long U-shaped channel bent out of some thin sheet stock and riveted vertically surrounding the sensor (open at the top and bottom) would act as a buffer for that sort of thing(?)  My only question would be if aluminum in close proximity to the sensor would throw it off since the light needs to dissipate in the liquid.  Would aluminum less than an inch away reflect the light back before it has time to dissipate and give a false reading??  Maybe I'm misunderstanding the sensor's function.  Anyway, I've got an email to Aircraft Extras asking about this... maybe they'll reply with some info.

   

  Any thoughts on the baffle?

Thanks Jay & Chris.  I saw the info on Chris' site, and also took notice of the mention of copying "Scott's" installation.  I just assumed that was S.Schmidt, and checked out his site.  I guess I overlooked the pics he sent the link for.  Sorry about that.

   

  Chris, your willingness to make "home improvements" all in the name of airplane building makes following your build quite exciting!  Can't wait to see the "add-on" pics on the site!

   

  do not archive

I don't know if the baffle is necessary.  Right now, even though it is calibrated for 5 gallons, I know that when I have 10 gallons in the tank with light turbulence the light will come on.  When I reset it, it stays off until it gets bumpy again (or if I have uncoordinated turns).  I think the baffle system would have to be pretty complex to keep the light from coming on.

   

  If you have a fuel totalizer you should be fine.  That fuel totalizer on the Grand Rapids can be calibrated and it is always within one gallon.
