Roger Lee Posted June 27, 2011 Report Share Posted June 27, 2011 I just heard that the company supplying Rotax with the new fuel pumps just back ordered them. That means they could still be a month away. It's a wait and see. Link to comment Share on other sites More sharing options...
DWT Posted June 27, 2011 Report Share Posted June 27, 2011 My fuel pump just failed with only 115 hours on it. I discovered it during a preflight and just barely noticed a couple of drips of fuel from the bottom side of the pump. I also turned on the electric fuel pump and the dripping was significant out of the mechanical pump on the engine. Had I not noticed the drips I would have taken off in the next few minutes and the results could have been not too good. I really have no desire to install another old pump but can't find the new model P/N 893-110. Anyone have any thoughts?? Link to comment Share on other sites More sharing options...

DWT Posted June 30, 2011 Report Share Posted June 30, 2011 electric fuel pump?? The mechanical fuel pump attached to the engine is the one that failed. I turned on the electric fuel pump to to put pressure on the mechanical pump in that they are in series in the fuel system and the mechanical pump dripped profusely which confirmed to me the mechanical pump was leaking.

I think he was wondering because the CT doesn't have an electric fuel pump. You must be flying something else. Tom Link to comment Share on other sites More sharing options...
bitten192 Posted November 26, 2011 Report Share Posted November 26, 2011 I just replaced my old AC Fuel Pump with the new style Italian pump. On the REMOS G3, the oil cooler mounting bracket had to have a few mm ground off the top to fit on the lower pump bolt. Also, the Italians left very little clearance to tighten the lower bolt. Have to grind down a 13mm crowfoot and use a small torque wrench to do the job. Don't forget to adjust the torque valve to compensate for the extra lenght of the crowfoot. By the way, Nick at REMOS Arkansas emailed me that I need an LOA to put the new pump on since it involves mounting the gas drain tube onto the oil cooler bracket. I think REMOS owes us a change to the REMOS Maintenance Manual instead of issuing each owner an LOA since all 912s will eventually need to put on this pump. If they insist on an LOA I think it should be "no charge". Ernie Link to comment Share on other sites More sharing options...
Roger Lee Posted November 26, 2011 Author Report Share Posted November 26, 2011 Hi Ernie, I don't see why Remos would need or want an LOA. Remos says to follow the Rotax manuals and SB's. This is a required change from Rotax when you need a new pump and all new engines have had these installed right from the factory for a while. I would bet the FAA would say since all this is true and Remos says to adhere to what Rotax says in the manual and SB's that you do not need an LOA. It is considered a factory part with a factory part number. I also agree that Remos knowing about the required new pump and drain line needs to issue an SB of their own stating it is okay and even how to mount the drain line. It may be worth another call from you and nicely mention that they should do so. I called them a few years ago about some manual wording and being in conflict with the FAA and they had it changed in a day and posted. Link to comment Share on other sites More sharing options...
Jeremy MacGregor Posted November 28, 2011 Report Share Posted November 28, 2011 I would tend to agree with you, Rotax makes modifications to the engines every year and no other parts require LOAs at least according to them. You may be right that the addition of the drain line might be enough of a design change that they feel an LOA is need to describe the installation and provide specifics on the length and routing of the hose. I haven't heard of any other mfgs. requiring the LOA for the pumps. Link to comment Share on other sites More sharing options...
