ROTAX 914 fuel pumps

Thanks for posting this, I had not seen this new requirement.  The previous 914 MML (Edition-2) did not have this requirement, but I see that it was added to Edition-3. In Edition-2, the fuel pumps were not listed under Time Limits, however in the maintenance schedule there was a requirement to replace the main pump (only) at 1000 hours. Considering this new requirement, it does not seem that there is any option to replacing the pumps every 5 years.

I’m curious about the justification for this. The injected engines use a similar electric pump set up, but are higher pressure than the 914 pumps.  So it makes me wonder if a 5-year replacement requirement will be coming for these pumps also.
