Filter position

I want to add a fuel filter that has a return line and I’m questioning myself as to where to put it. Since it has a return port, should it go before or after the pressure regulator? My current setup is pictured below.

If using a stock mechanical pump, I typically will put a filter directly after it to protect systems down flow... like a regulator and carb. If electric pump, pre and post pump, with tighter filter (lower micron) on the post side, which is before the carb/regulator.

That’s what I have now. The clear one in the picture. I wasn’t sure if a filter with a return line should be before or after the regulator. I’m trying to cut down on a heat soak problem.

Do you have a sending unit at the tank with a return?

Reason I ask is I ordered the below filter but I have a stock sending unit.

No. The sending unit only has an outlet. The previous owner put a provision in the filler neck for a return port. I just picked up a 33040 from O’Reilly’s. Similar to yours only the return port is parallel to the out put line.
