Hey guys,
I was putting firesleeve on my fuel lines in the engine compartment and was searching google for an easier way to do it.
I was struggling with a 1 1/2 foot length to get it on the hose and was wondering how the hell I was going to get it on the 3 foot
piece from the gascolator to the fuel pump on my rotax. I found this tip on the RV list and figured I'd pass it on to you guys
when you're there one day.
.....old mechanic showed me how to install firesleeve with compressed air. I was working at the Cessna service hanger in Wichita back in the late 70's.
I was a young A&P at the time and had been struggling with the firesleeve on
an oil hose for at least 15 minutes.
This guy comes over to me and say's "let me show you a trick". I said
"please".
He takes a air hose with a blow nozzle, sticks it up in one end of the fire
sleeve and tells me to put the other end on the oil hose.
He tells me to get it started and then put my hand around it and squeeze to
trap the air inside. By controlling the amount of air you let out, the
firesleeve expands and the extra air escaping makes the firesleeve slide on
like a hockey puck on an air table. I was amazed and remember it like it was
yesterday.
Hope this helps someone.

I have to say this works great!
I also found that if you use a 16 gauge piece of wire and a barbed coupler(has barbs on both sides to connect 2 pieces of hose)
Tie a knot in one end of the 16 gauge wire and run it thru the barbed coupler, put the coupler on the hose with the knot going
in first, run the wire thru the firesleeve and pull the hose thru the firesleeve, its alot easier to pull it thru than push it!
I used a little extra fuel hose and just cut the coupler off.
I would like to put some high temp RTV on the ends of the fire sleeve, for dirt oil getting into the soft inside.
Will it have any bad effects on the goodyear rubber hose from Zenith? I know recently that Rotax replaced some
preinstalled hoses on some engines that had them(mine didn't) for somthing related to this.
Checked the archives but did not find any archived messages related to this, although it was mentioned recently.
The firesleeve is installed already so the RTV seems the best choice right now.
Thanks for all the great help.
