Tom Baker Posted March 2, 2022 Report Share Posted March 2, 2022 The pumps are in the fuel pump pack, along with piping and check valves. On the CTLSi it is loacted under the floor of the baggage compartmemt on the left side. It is a PIA to remove for replacement of the hoses for the rubber replacement. I'm surprised somepone hasn't suggested drilling holes in the bottom of the fuselage for access to the nuts. It is far worse than accessing the fuel lines in the CTSW wing root.

Roger Lee Posted March 2, 2022 Report Share Posted March 2, 2022 I also think the placement of the CTLSi fuel pumps was a terrible idea. Quote Link to comment Share on other sites More sharing options...
678Papa Posted March 3, 2022 Report Share Posted March 3, 2022 Airhound, The answer to your question " was it the wire/pin crimp connection, or the pin connector seating? Or…how do you think whatever it was with that pin it came about?" A little surprisingly, once we found the pin and wire circuit with the continuity issue, the wire/pin crimp connection was fine. The problem was in the female side of the connector. We had to slightly squeeze the female connector so it was a slightly tighter fit with the male prong. Why this happened after 7+ years I am not able to answer. As you would expect, the secondary pump is powered by it's own separate circuit breaker and wiring.

Anticept Posted March 3, 2022 Report Share Posted March 3, 2022 Which type of female pin did it use? This type, which is split down the middle? Or this type, which is a solid barrel but has contacts inside? Quote Link to comment Share on other sites More sharing options...
cdarza Posted July 20, 2022 Report Share Posted July 20, 2022 How often are the mechanical pumps supposed to be replaced ? 912ULS btw just found this link which was quite informative re fuel pump: https://electricmotorglider.com/wp-content/uploads/2018/09/912-Fuel-Pump-Web.pdf Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted July 20, 2022 Report Share Posted July 20, 2022 Rotax would like them done every 5 years with the rubber change. Most don’t and just do it later on unless an issue pops up. Quote Link to comment Share on other sites More sharing options...
