photo of red cube in the tunnel

[pa38112]

I have seen tones of photos of the red cube mounted in the engine bay and on the fire wall. I am planning on mounting mine in the tunnel after the electric fuel pump (RV6A). Could somone post photos of this mounting configuration ? I'm looking for ideas on the bracket.
Thanks !

I know you are out there, at least acording to the threads - maybe not, and that is why I can't find photos.

Lots of folks have troubles with that location and have moved it to the engine compartment. I would recomend against having it thee and put it between the servo and the spider. Let me know if you want more info about the problems.

I wanted the unit in the tunnel as I felt it may indicate FWF leaks where other locations may not. Here are some build pics. I don't have any pics of the extended doghouse or finished install but if your interested I can send you a photo and the layout sheet to bend up the DH extension.

"Lots of folks have troubles with that location and have moved it to the engine compartment. I would recomend against having it thee and put it between the servo and the spider. Let me know if you want more info about the problems."

I have read many thread on the subject, and concluded from them that the issue is more related to the transducer that EI used before the red cube. With the red cub the only problem I am aware of is that the reading is affected by the electric fuel pump. This does not concern me, because I do not plan on using it to measure total fuel consumption. I am more interested in my fuel flow during leaning/cruse when the electric pump will be off.
If you have additional information I would be more than interested in it.
Thanks. - Also, I may have used the wron term when I said "in the tunnel". My fuel line run up the left side of the fuselage about 1" off of the floor. This is where I intend to install the red cube - on the left wall, about at my knee, 1" or so off of the floor.

I thought the 6 and 7 shared the same basic fuel line routing. Sorry about that.

Even if you do plan to use it to measure total fuel consumption, it isn't a problem. The error is small enough (at least on the RV-10) and the electric pump runs so infrequently that the net effect on the fuel consumption data is inconsequential.

Gary, can you elaborate on what you have seen as trouble with that location (in the aft of the FW cockpit fuel line route). I have seen red cubes installed that way and even one of the VAF guru's has his in that location in his -6. ( DAR Mel )

I cannot find many negatives on VAF with the exception that the accuracy of the reading may be degraded slightly. I know EI suggests FWF but then again the fuel fire risk also has to be much higher.

Thanks for any info you can supply as my red cube is on my ToDo List (freshly replaced by EI because I had an uninstalled older model .... Thanks guys)

I mounted mine 3" aft of the firewall, in the tunnel area. I did make a raised tunnel from the fuel selector valve to the firewall, so the cube is hidden in this area. I have had no issues from mounting it here.

Do you have a photo of how you did this ?
