Red Cube Firewall Bracket Question
Ok, a lot of information here on the red cube. Every installation I have seen where it's mounted on the firewall have it mounted to an angle bracket. Why?
The instructions give three mounting orientations.(out up,wire up,5 bolt plate up). In my case I would like to mount it to the firewall with the 5 bolt plate up and secure directly to the firewall.
Just for the record I'm not against making a bracket if that's the preferred method. Just like the simplicity of the direct mount.

Red cube
Jared. I put mine on the fire wall with a peice of
angle. The reason being to be able to mount it facing
Up so the bolts are verticle. Seems to me I read in the instructions
It was recommended to be mounted this way.

The wires on the FT-60 red cube should be pointing up according to the directions .

They must have revised the instructions. My instructions for the FT-60 give three possible mounting positions.
Al, I think my flow direction is different than most carbed installations. I might still come take a look at your setup sometime.

Here's a picture of mine mounted on the firewall diagonal stiffener, with four #10 screws: two thru the stiffener and two thru just the firewall to close the gap behind the piece of angle the red cube is mounted on. I did use some red RTV to seal behind the angle mount/firewall.
The angle mount mounted on the firewall:

The Red Cube mounted:

I know of one other builder that used an approx. 9" long piece of 1/4" angle on his firewall to mount his Red Cube. Needless to say, it ain't going anywhere. And you know who you are!

I spoke to the manufacturer about mounting. They advised against firewall/solid mounting. Their suggestion was to let it float between two hoses.

This what they told me too. It has jewel bearings for the pelton wheel.

This may be a dumb question, but what is a "Red cube" ?

Electronics Internatinal FT-60 fuel flow transducer. Very popular and compatible with probably every EFIS and engine monitor.

Where in your fuel line between the firewall and carb idoes it connect?
Mine is angle mounted on the lower right side of the firewall between the electric fuel pump and the engina driven fuel pump. It fluctuates about 2 to 3 gph until the fuel level in the tanks is about 1/2 full then fluctuates 1 to 2 gph. Overall, the fuel needed to fill the tank is within .2 gallons of the fuel used. It just doesn't maintain a steady reading.
