In my experience, silicone rubber products swell horribly when exposed
to petroleum. Never tried hot petroleum, but it's got to be worse!

'There is some concern over the ability of the existing rubber oil return
hose (in the Rotax engine installation) to withstand the extremes of
temperature created by the nearby exhaust silencer even when protected with
firesleeve. It has been suggested that Teflon hose might be the answer as
it can withstand temperature up to 200C as opposed to the normal limit of
130C for the usual rubber hose. I have noticed in a specialist spares
catalogue that silicon hoses can withstand temperatures up to 300C. Is
there any reason why this type of hose should not be used instead?'
'I have just bought the ACI Stall Warning device and very good it looks
too. Although it is very easy to mount the sensor onto the Europa wing,
routeing the cable and positioning the sounder looks to be more difficult,
particularly retrospectively on a Classic wing. Please could anyone who has
done this give me details how they went about it.'
