It has been over 11 years since I first flew my RV-9.
In that time I have changed the engine (O-290 to O-360) due to a prop strike. Last year I found a crack on my engine mount and replaced that.
I started my Condition Inspection on Friday night and so far so good. Compression on all four Cylinders are normal. Last year #3 was low and I was using oil like crazy. Just recently I noticed my oil consumption was back to normal and sure enough, the sparkplugs were all dry and the compression was back to "normal".
Last year I replaced the O-ring on the gascolator and lubricated it with fuel lube, which I would always do. This year I removed the unused plug on the gascolator and it pulled right off.
After the gascolator was reinstalled I decided to "bleed" the fuel pressure line. Over the past year I would get low fuel pressure warnings on my EFIS and have replaced the wire, sensor, etc. and it would still come back on occasion but once the engine warmed up, it would go away and not come back on. Also, even though it would read 1 PSI in a full power climb, the engine never sagged, so I know it was getting plenty of fuel.
So, this morning I turned on the electric fuel pump and started loosing the plug on the "manifold" that holds the fuel pressure sensor until fuel started coming out. I was surprised at how long it took for fuel to come streaming out, once it first bubbled. With fuel leaking out, I tightened the plug back up and then turned off the fuel pump and master.
I will report back, once I'm flying again to let you know if this solved my low fuel pressure readings.
