Doing my first condition inspection and everything going great until removed tunnel cover and saw some blue staining on floor and all over boost pump.....obviously a leak so I began trouble shooting. After pressurization I noticed pool of fuel coming from under pump near front and felt fuel there. I had no leak during phase one I know because I flew with cover off. Initial thought was poor connection between pump and firewall (my FF senor is not in tunnel). I re-torqued line and still leak. I removed and inspected line - looked good so cleaned and replaced and still leak. Then I remade entire line replaced and still leak. My suspicion now is that pump itself is leaking because the stain is mostly on pump and floor but pump is raised off floor (so couldn't get stain form other part of system not directly connected to pump) and none of those other fixes worked. Have any of you seen this before and if so how would you test to see if pump is bad?

Assuming you have an afp pump, give don Rivera a call on Monday.   Either don or Kyle can answer your questions.   They’re pretty good folks to work with.
