i should add that the ticking noise dies off as the system is pressurised. but if yours ain t ticking then there maybe some other gremlin at play.
others on here may know better and i'd be happy to hear about it but yes i do believe it is a backup system. do you have an inline filter as well? i have found that buying a plane of this age with this many owners and maintenance regimes, its hard to know what is standard and whats not. i have an inline (automotive fuel injection- off a toyota camry i believe) filter fitted directly to the downstream side of my electric fuel pump (between the fuel pump and fuel valve) ________________________________ From: [email protected] <[email protected]> on behalf of Jarek Steliga <[email protected]> Sent: Monday, November 11, 2019 12:01 PM To: Laurie Hoffman via dog <[email protected]> Subject: [DOG mailing list] H 36 electric fuel pump Hi, How to make sure the pump functions properly? Does it produce some audible buzz sound when switched on? When I disconnected the fuel hose at the carburetor and switched the pump on, no fuel flowed. Is this pump just a back up in case the main engine driven pump fails during take off / landing? What is the electrical pump's location relative to the shut off valve? As per diagram between the fuel shut off valve and the carb? Tank you in anticipation Regards Jarek
