Hello!
So I recently finished the install of the Dynon D-10 EMS which is great except for the fact that now that I have a working fuel psi gauge I have noticed significant drops in fuel PSI on high power events like takeoff or climbs without using the boost pump. It'll drop down to 1 PSI with the throttle wide open. When I use the boost pump it'll put the pressure back up and hold it around 4-5 after that. It'll maintain good pressure at cruise.
I'm just wondering if this is normal. Looking at the O-360 1A1 section it states 8 MAX, 3 nominal, .5 minimum. My question is, does this seem normal or is it indicative of a failing engine driven pump? I haven't noticed any significant loss of power during this drop.
Thanks all!
