| Subject: | 5-Year Rotax Rubber Replacement |
On my RV-12, with Rotax 912ULS I am thinking of replacing all hoses with the Aircraft
Specialty (AS) PTFE hoses.
The 5-year replacement "kit" from Cal. Power Systems, seems to have some hoses
that duplicate (more or less) those that I will be using from Aircraft Specialty.
I need to know what rubber parts to purchase beyond those from AS, particularly
the carb parts.
Can anyone point me in the right direction? Hopefully Roger Lee can help with this....Thanks

Just some food for thought. This is certainly a personal preference item.
I have done 7-8 RV12 hose changes.
Those Teflon hoses are expensive, but yes they are the best. If just the fuel aren't
they $500+? They are supposed to be a 10 year hose?
If you add oil hoses that has to be up around $1000.
The standard rubber fuel hose would be about $15-$20. If you double that for
the 10 year mark that has a pretty big price difference. The standard 13mm (1/2")
oil hoses would normally cost around $35-$45 verses over $500+ for Teflon.
If you are switching to the Teflon hose and since these are pre-made you will
need new fittings for these new hose to fit them to the engine. They may come
with them I do not know, you would hope so. They may or may not come with fire
sleeve I don't know. There is a good chance they come ready to go with fittings
and fire sleeve.
That said you would have labor included for the second hose change and that may
be around $500-$800.
Depending on the shop that changes the hoses a normal full hose change parts and
labor may cost any where from $2500-$4000. The high end number would be a little
more expensive shops.
If you use the Teflon fuel hoses you will still need:
13mm oil hose (from Spruce)
17mm coolant hose from Spruce
25mm (1") coolant hose
90 degree 17mm coolant hose
carb diaphragms
Carb sockets
66mm carb balance tube hose
Oetiker band clamps or fuel injection clamps for standard fuel hose
Fuel injection clamps for the oil line.
Band-It band clamps for the fire sleeve. Fire sleeve may be re-usable if the hose
lengths are the same.
The thing with Spruce's kit is they assume you will take certain things apart and
will need things like crush washers. The thing is you don't need to disturb
the fitting just pull the hose off and replace it. I usually need need as many
parts as they want to sell so when I need things I just buy specific parts and
that can save quite a bit which I can then pass on to the customer.
