I've searched the archives but haven't been able to find an answer to why I am seeing variable fuel pressure readings (2-12 PSI!!) on my GRT EIS 4000. My engine is a carbed O-320. All other engine instrument readings seem within normal ranges, but the fuel pressure varies rapidly up/down/up/down in seconds
Engine seems to cruise just fine despite the readings.
One suggestion I did find was to look for a blocked breather, and I will. I'd appreciate any advice on where to look, or whether I should replace the engine driven pump as a start???
