That's how OEM fuel pump assemblies do it, effectively. The entire 'basket' that houses the pump has a check valve in the bottom for the pump to pull from. The return line fills the basket, or in the case of a returnless setup, the regulator is in the basket, which effectively keeps it full (and overflowing, really) at any time. As an aside, I don't have the front dimensions yet, but I was looking around at fuel tank suppliers and found something that might fit.
