On June 24, 2013 Rotax released a new SB on the old style fuel pumps. It is issued as "Recommended" rather than "Mandatory."
Before this one, all of the Rotax SBs about fuel pumps, fuel hoses, oil leaks, washer replacement, improperly torqued oil pump bolts, and possible crankshaft journal crack have been not applicable to my engine serial #.
Here is the SB (actually 2 of them issued the same day), I figured someone else would start this thread:
This is 14 pages
This is 2 pages
The SB notes that "all fuel pumps have a 5 year life" in accordance with the Line Maintenance Manual. Thus fuel pumps prior to 2008 (with s/n starting 07. or 06.) should have already been replaced. It goes on to say that all fuel pumps with part # 892542 and 892546 (mine) are affected and also lists engine serial number ranges.
Fuel pump types 893110, 893114, 893115 are not affected.
The 14 page version has the details for replacing AND reusing the existing fuel lines and there is a video on that as well. Basically you cut the two old fuel lines at the pump then put them on the new pump with 4 of those Oetiker band clamps (2 for the rubber, 2 bigger ones for the firesleeve.) Of course you have the 5-year Rotax Rubber Replacement Recommendation to deal with...
The new pumps have longer connectors on them that make up for the cut-off length of the existing fuel line.
I have not inquired about price. My old-style fuel pump has less than 60 hours and has shown no leaks. I imagine there might be a "run" on them. Since it is "recommended" rather than "mandatory" I imagine there is no under-warranty price break. Anyone know? What are y'all doing?
Let's hear from our friends at Lockwood!
