On the day I picked up my 93 J from annual, I noticed a slow drip of fuel behind my nose wheel and forward of my fuel sump on ground, perhaps a drip every 20 seconds. Shutting off fuel valve stops it.
Turning on boost pump causes it to leak more.
My AP states that it’s the boost pump seal that can leak in cold weather, I’m in Florida and weather has been seasonally colder in recent days. He states once weather gets warmer in a few days it will stop and its “common” for Mooney’s.
I’ve not seen any such posting on this “common” problem on Mooneyspace and have only had the airplane 1 year but it never leaked before.
He says not to replace the pump “till it needs it”, I’m not sure what to believe, I flew it once and it dripped at my destination. I would understand the issue more if my wing fuel tank was leaking, but this one is closer to the engine.
It appears to be a Weldon A8163B, $1269 from Spruce. I haven’t checked yet whether it’s under an inspection panel or the one piece belly, but believe once I get access to it will be able to see where it’s actually dripping from. My AP is on vacation till second week of January.
I would appreciate any thoughts on this.
