[DG] [DG] Autopilot EV-150 Type 1 hydraulic pump connectors leaking

Hi Daves320

Sorry to hear of the leaking issue, our handbooks discourage the use of thread sealants, simply because in practise they are not generally required and leaks are rare. Most installers use too much or use PTFE thread tape which tears off and gets ingested in the pump leading to failure, so we generally discourage their use.

We approve use of LocTite Threadlock, which can be applied sparingly to the threads once they have been degreased and cleaned, be very carefull not to use too much as the excess will run off and could jam the pump valves. DO NOT use Threadtape, since this will tear off and strips of it will damage the pump as it gets sucked in.

Since all three connectors are leaking, that does seem suspicious and the thread form of the additional adapters should be checked.

regards
Derek
