My ship is a 2018 P2008 Turbo demo. unit bought from a dealer last August with about 45 hours. Since I took delivery I noticed a drop of yellow fluid on the nose gear trunnion, usually after the plane sat for a day after flight. There was never enough to drip on the floor. I kept searching for the source as it wasn't engine oil, hydraulic oil or antifreeze and couldn't find any evidence of the yellow oily stuff anywhere else. I checked every fitting and nothing showed up. Finally took a sightline from a creeper while under the nose gear and decided it had to be coming from the fuel pump manifold. When I got my fingers underneath the cross tube "B" nut there it was, an oily substance that could only be mostly dried fuel residue. I drained some fuel and let it evaporate to confirm what it was....see photo. Somehow I thought mogas was clear....not so.
I'm a snowbird to Sarasota so I called Josh at Tecnam in Sebring with what I found and he told me to bring it in. Josh and Sean were great. They confirmed all the manifold fittings were tight but there was an obvious seeping from the lower fuel pump cross tube fittings. They took things apart and found the cross tube with "B" nuts a fraction of an inch short. Without parts to replace it they put it back together and tightened it first, before the others, hoping for a better fit. It appeared to be fixed but still seeps a very small amount. I'm to bring it back in when they have new parts but feel it's safe to fly till then. mb
