robert ceasar Posted January 23, 2014 Share Posted January 23, 2014 sir good day! i'm robert from the philippine air force. our c130 spr drain pump operatesmore than 10 minutes while in the instruction it says 5 minutes only. we already repalced the pump, drain valve and the one way check valve at the rear spar of the tank nr 3. My question is there other solution to this problem? thank u sir robert Quote Link to comment Share on other sites More sharing options...
andrewelsh Posted January 23, 2014 Share Posted January 23, 2014 Hey Robert, How many pounds or fuel are you transferring while the drain is on? Do you hear the pump cavitating at 10 minutes or before? Quote Link to comment Share on other sites More sharing options...
robert ceasar Posted January 23, 2014 Author Share Posted January 23, 2014 200 pounds more or less sir. at first it cavitates after 10 minutes sir but after multiple used we did not continue to use the pump because were afraid that it will over heat.

robert ceasar Posted January 23, 2014 Author Share Posted January 23, 2014 supposedly as per instruction the pump should only operates 5 minutes to darined all fuel in the spr manifold sir. so we decided to stop using the pump after 5 minutes and then we were just manually drain the remaining fuel in a pail sir. but it took some time and delayed our mission sir Quote Link to comment Share on other sites More sharing options...
