Fuel return... how much, how fast?
If you unplug the fuel return line put it into a bottle, and run the fuel pump, should you get any fuel flow? Or do you have to actually run the engine for their to be any fuel return?
Would idling be enough for their to be fuel return?
The reason I ask is because I want to know if there is still any old gas in my lines or rails.
If you don't drive a car, does gas simply drain back into the tank at some point?

I unhooked what seems to be the IN line on my SARD regulator and only the gas already in the line came out (maybe a few ccs).
So if I've only had the engine running for a total of about 20 minutes, is it possible it's still being fed bad gas?

Assuming the feed lines are 3m long there should be at least 1.5 liters of fuel in the lines, which IIRC have an 8mm ID.
I have 30 liters of good gas in the tank. I think it was almost empty when I put the fuel in.
