Yes. I'm just not sure why the electric pump in the tank is something to get rid of. Maybe because of the issue I'm having?
Not related - the in-tank pumps are challenging in their own way, but the diesel system is simple, reliable, and easy to service (two bolts, and two fuel fittings to change the pump without messing around with the fuel tank at all)
If the swap was done from in-tank petrol pump to just a fuel pickup tube, the pickup tube may not go all the way to the bottom of the tank, or you incorrectly are using the return line as the pickup. If the tube is close to the bottom of the tank then consider fitting a fuel sock, if not close enough then have a new pickup brazed onto the existing fitting.
Sorry I missed you again!
