No Fuel pressure

[aussieflyer1]

Today I went out to fly and after start up I noticed I had no fuel pressure on my Van's mechanical gauge although the needle when to 4psi with boost pump on. When I turned the boost pump off it stayed at around the 4 psi but after shut down and restart the same result no reading without the boost pump.

I checked the power to the gauge and all good, I'm guessing it's the sender???

Any advise to solve or where to look for the issue.
Thanks in advance.

Was the engine still running with the boost pump off?
Fuel pressure gauges are notorious for reading incorrectly or not at all.
It's difficult to get dependable readings at that low pressure.

Good point...yes it was still running and it sure wouldn't without fuel pressure.
I don't start my engine with the boost On, for some reason it floods very quickly. I have power at the gauge sooooo maybe it is the issue though.
