Default Red Cube?downstream

Thanks Tom. I was looking at putting it between the pump and servo, but I soon saw that those hoses are BIG?hence my question about SIZES and lengths. Putting it between the servo and spider looks like it eliminates any need for reducers/adapters, so that's what I'll do. I'll get back with you about hoses after I look at exact location, per your suggestion.
Do you have any pro/con advise about allowing the cube to float, vs. mounted on FW?
Thanks

Default Has this been decided?

I just spent the last hour reading about 50 posts - all with a different opinion on where and how to mount the Red Cube. What is confusing is the different locations for FI and carbs. I have a carb and there are more locations discussed for carb engines than FI

Im about ready to throw it away and just use a stick to know my fuel use!

I was in the same quandary at that stage. Then I happened upon a builder's website (it may have been Randy Lervold's) that showed the Cube in a place that would work perfectly for me. I put it there - between two hoses in the line between the servo and spider - and it has worked great ever since.
I recommend you put it in a place you can access readily ... Red Cubes fail every now and then. My first one had defective threads and had to be replaced at 12hrs flying time.

Thanks Terry. I spoke with Tom and he said to mount it and then tell him what length hose I need and he will make them for me. I told him to quit milking his knee - near death experience and get back to work!

Default Here's where I put my Red Cube on my -8.


Awaiting new hose from Tom to run between Cube and spider.
Warning: untested. Still building.

Your chosen location is going to be the high point of the installation. Just what EI's installation guidelines say to avoid.

As the op I thought I would share where the cube ended up.

Tom made a short hose with a 45 on one end to go to the servo (rear outlet), keeping the cube as low as possible.

Actually, it's still uphill to the spider from there, per my installation instructions. I Googled for more info, and it looks like there are "old" Red Cubes, and "New & Improved" Red Cubes. I found a 25+ page set of installation instructions on line that I think pertain to the older model. My Red Cube came with a 2 page install sheet, that says: "…the fuel line on the outlet port should not drop down after exiting the transducer."
Pretty sure I complied with that, but will double check…especially in a level flight attitude.
There was no mention of bubble-trapping loops in my installation, but I DID see references to that in what I think was the "old" manual.

Thanks for keeping me honest. Love the feedback on this site.
