Hello,

I have about 20 hours on one of the new style "Corona" fuel pumps.

Yesterday while returning home on a cross country the fuel pressure started drifting. 7, down to 4, up to 7, 8 ,9,10,8,7... All very slow. 10,12,11,13,...eventually I saw 20.

If the pressure went low I have an electric pump inline but nothing I can do about overpressure. The engine didn't miss a beat and the fuel flow meter stayed constant. I tried clearing the engine a few times without much change.

Of course I'm thinking instrumentation so before ordering anything I'll need to put another pressure meter on a T and run it on the ground to see. If it all holds steady at 7PSI like it has all along I'm not sure what to think.

Has anyone heard of a similar problem with the new pump? Or old one for that matter. I'll call Lockwood on Monday and ask the same.

Thanks in advance,

Mark Napier
