Not every ounce of fuel that goes through the high pressure pump is used, that is the job of the fuel return line that goes back to your fuel tank.Asphaltines wouldn’t be present in fuel that has yet to be run through the fuel system. In any event they wouldn’t be the at visible. It’s usually a sludge at the bottom of the tank. What the OP has is a much larger debris, likely from a deteriorating fuel storage or supply issue at the station where the fuel was purchased.
