Fuel return line

[DK_XJ_1992]

I want to supply my AUX heater with a tee split in the return fuel line. Does anyone know if there is a check valve in the return line, so that I cannot suck fuel up through the return line?

no check valve but the return line does not reach to the bottom of the tank.

Do you know how deep it reaches?
