Rv-12iS fuel pump replacement

[rcarsey]

Seems we may have a "mandatory" fuel pump assembly replacement on the horizon.

Rotax released this SB today (.pdf also attached below): https://legacy.rotaxowner.com/si_tb_...b-912i-013.pdf

I'll have to check my s/n tomorrow.. and Van's will probably have their own SB if any of us have s/n's in the affected range.

Where is the serial number located....on the fuel pump assembly? The fuel pump assembly inconveniently located on the backside of the bulkhead?

Yes, they are printed on the pump housings. You should document the model and serial number of everything you can during your build, as this won’t be the last time you’ll need to check for one of them.

Page 9 of that bulletin shows you where to look (on the pump itself -- so hopefully they're oriented in such a way that it is visible without removal).

Page 10 also states: "The fuel pump assembly (the stainless steel box, pumps, check valves, etc) has its own serial number, which may or may not be the same as the number on the individual pump."

I know someone will correct me if I’m wrong, but the SB appears to be for pumps with part number 889694, does it not?

I am also trying to understand the significance of the listed part number 889694. My part number on both my pumps is 889691.

I called Leading Edge; they just heard about it themselves and have no information yet.

I am going to keep an eye on this forum, and wait a week or two before calling Rotax or Leading Edge again.

I am also concerned about who pays for the replacement pumps. Is this a warrantee issue or owner responsibility?

These pumps are expensive.

I had the same question about the part number 889691 vs. 889694 shown in the service bulletin, so I called Lockwood this morning and they said to only look at the serial number and not the part number... strange.

+1 to being slightly confused on this one.

My pumps have a visible part# of 889691, not 889694, but my serial #s are in the affected range.
But if you look figure 1 on page 11 in the appendix of the SB, it shows there are 2 different stamps on the pumps, and the 2nd one in figure 1 shows 889694, whilst the first show 889691.

Due to the orientation of the fuel pumps when installed, I cant see the 2nd stamped # without pulling the whole fuel pump assembly, so not sure at this stage how to proceed or if my pumps need changing
