Re: Low Fuel Pressure w/ Backup Pump On
by Tyler Hathaway » 2 years ago
Um, not really, haha. My fuel pressure usually drops a bit when I first turn off my aux pump, but I do have that bypass...
On or off, I have never had my pressure go near Rotax's stated minimum (0.15 bar).
But where exactly is your pressure sensor? Is it where the diagram shows it or somewhere else?

Thanks, Tyler. So if that turns out to be the case, then does it make sense that fuel pressure is lower with the Facet pump turned on and higher with it turned off? I get back with you once I take a look at the installation.

Tyler, the fuel pressure sender is on the firewall.

Haha, OK... I meant where is it, in your fuel system, relative to the various pumps, pressure regulator, etc.

I'm not the builder so I don't remember exactly but when I get back to the hangar in a few days, I'll take a look and get back with you. Since it's carbureted there is no pressure regulator though.
