I bought a piece of the largest Aeroquip Sleeve i could find which is a -24 and is a little too tight to get on.  What are others using to heat protect the cube?

Duh! How easy is that -- surely overlooked seeing the obvious.

I'm not sure of the wisdom or the science of firesleeving the red cube especially if it is mounted downstream of the fuel control unit fuel shut off as the manufacturer recommends. My two-year-old cube seeped for the first few weeks after we put fuel to it and then the gasket swelled and sealed itself but I like to have it open for inspection and it seems to me that if it did leak the sleeve would just concentrate the fuel. The unit does self cool from the fuel flow so I don't think heat is an issue. 



What am I missing?

Where most folks are mounting, in front of the sump and near the fuel 

servo, is upwind of most exhaust pipes and anything else really hot. I 

too do not see the point of firesleeving the cube. I've had one on my 

Mooney for about 6 years without firesleeve. Don't recall anything in 

the STC instructions calling for it. In fact, the STC called for 

installation between the mechanical pump and the fuel servo, which 

works, but is higher pressure than after the servo in the line to the 

flow divider.

In my case my lycoming came set up with the fuel line from rear of airflow performance servo up through bottom baffle between cyl 1/3 .  I split the line to mount red cube where it would fit.  It's close to the exhaust enough where I  feel better about shielding it as much as possible from heat.  It's near the combined part of thei pipe so I can't put a heat shield on the pipe.

I've removed the bracket I had made so now it's actually closer to 3 intake pipe

Can't you but fire sleeve in sheets?  Just roll it around the red cube a couple of times and secure with ss hose clamps.  

I seem to remember having to do that on my p-180 when I installed the fuel flow sensor on it

Actually after looking at the acs firesleeve mentioned I see it's the same dimension that I have already so back to square one.  I guess I'll wrap with cut pieces of sleeving and clamp.  I was looking to know if anyone else had the cube in this location and their experiences with heat whether it's a factor or not.

Dave, please take this with a grain of salt .... I'm still building 

.... but from my perspective you're spending a lot of time on a 

solution to a problem that just doesn't exist.  I can't speak to the red 

cube specifically, but so far I've had really good results from various 

flow senders mounted .... naked .... in the engine compartment.  There 

was one failure from a sender that came with my Piper that had 1800 

hours on it. That was many years ago and I'm sure technology has 

improved since that one was manufactured.

Linn, you're probably right--- I think just to satisfy my gut I'll wrap it and move on, thanks.
