Along similar lines,

 

Perhaps a sound comparison as well as pressure check between the two pumps (assuming they are the same Mfgr and model) should be a pre-flight check.

 

Of course, if they sound differently, which one is good and which one is about to shoot craps. but at least there is a warning and opportunity to trouble shoot, on the ground.

Chris,

Is there a difference in sound between the new pump and the old one you are still using?  I think that they should both sound the same.  Mine do.

Subject: [FlyRotary] fuel pump replaced

 

I replaced my faulty fuel pump.  The new pump is MUCH more quite.  I suspect the old one was on the way to failure for a while and finally when belly up.  It was really noisy.  When I took it off I applied power to both independently and the old one was just plain dead.

 

I hope I have addressed the few gremlins that has kept me on the ground the last few weeks and will get to fly later today.

 

FWIW.
