rotax 912 oil and water hoses

I'm in the process of getting my Rotax 912 back in order. I'm going to inject it with a LAD injection kit (French programmer which was originally a programmer for rally vehicles) and I'm going to replace all my hoses. What do you think if I replaced them all with aviation hoses?

I'm not sure what you mean by "aviation hoses." Do you have specific products in mind?

Hello,
I looked but in fact aviation hoses are designed to have specific fittings and not installed like that with classic clamps.

There is a company in Wisconsin, Aircraft Specialty Hoses (something like that). They make good hoses that they claim have no life limit, and are the only place that seemed to have some of the metric Rotax fittings if you had a European origin engine (not only SAE/JIC fittings (and / or any combination)

If you deal with them, let us know what you think of the product and the service (late in the year 2025 price)

Okay, thanks. I'll find out. At worst, I have a company nearby that makes custom hydraulic, compressed air, and other hoses for public works and automotive equipment, so I'll ask them too.

I have had no luck with approaching any non-aviation company and asking them to fabricate anything for my airplane here in the USA.  They have always asked what the product will be used for and when I answer truthfully they apologize and refuse to do the work. Liability reasons, they explain. Hopefully you will fare better. Your injection system sounds interesting, please keep us updated as you move along. Does the system require battery power at all times?

Hello, I will keep you informed.
I plan to put the injection between November and December.
For information I will order here http://www.ladaero.fr.
There is an injection system from EdgePerformance to see here https://shop.edgeperformance.no/produkt/edgeperformance-produkter/i... too
but I prefer to stick with my first choice
