Greetings:
Any words of wisdom on the following appreciated. My RV 6 has a 0-360. On a past flight, the fuel pressure dropped to .5 from 4 during climb to 7500. I turned on the boost pump, changed tanks. Pressure returned 4-5. I turned boost off, pressure slowly dropped to .5 again, engine has purred along all this time. I leaned the engine and fuel pressure went to 2. It stayed there till 3000, then returned to 4. The engine fuel pump was changed recently due to leak out the overflow line indicating failure of diaphragm. However the low pressure had occurred once before. I had wrapped the lines and red box, after changing fuel pump.
Not showing any obvious fuel leaks.
Looking at all the low pressure threads, I’m still scratching my head.
Comments appreciated.
