Fuel Flow at Start
Should there be fuel pressure indications with the electric pump on in the cockpit? Any other suggestions where to look? Pump seems to be running but not sure if output is enough.

Re: Fuel Flow at Start
I see this is your first post on this Forum. Welcome.
Does the fuel pressure always increase when the electric fuel pump is turned on?
My IO230 in the twin had a similar set of symptoms awhile back - for me, the fix was overhauling the electric fuel pump. Since the electric fuel pump is a big safety feature, we got it fixed right away. It has saved us an engine out more than once.
I have to say the lack of fuel pressure after starting makes me think the engine driven fuel pump may also need attention. The engines on the twin, even at idle show some fuel pressure on the Shadin fuel fuel gauge - I haven't had this circumstance so that is just speculation on my part.
Hopefully others will chime in because I'm a learn-by-checkbook owner as opposed to a trained mechanic.

Re: Fuel Flow at Start
I have a 260B as well. Any idea how the contamination got into what I assume is a closed system?
Thanks, Don

Re: Fuel Flow at Start
That did not fix my problem. Reconnected all the lines and back to no pressure on the FF gauge. Showing 20 psi out all the way to divider. With #2 line off and blocked closed we get 13 gph on gauge with electric pump and mixture rich. No pressure on gauge with it unplugged. Anyone have any ideas?
