Default Gs400 Fuel sending unit/ pump help

So I need the upper part of the fuel pump sending unit mine has small cracks and is causing evap faults. The gs300 has return style 2 lines and mine the gs400 has only 1 and I'd like a new one has anyone had this issue and a simple solve? I'd prefer not to have to run an extra line and regulator and all that!

There were not two lines on my stock GS300 assembly. There was no return line on a 97+ 2nd gen GS. Only the turbo aristo of that vintage would have had a return line. I'm not certain, but I would be surprised if the assembly on the 300 is any different than the 400. Double check part numbers from Lexus.
