Misc. 258 Weber fuel pressure regulator return plumbing?

[CJ27]

Hi,
I learned enough just looking around on this forum that I wanted to sign up and learn more. My only engine experience is read, research, and attempt. I'm going to try a Weber pressure regulator to determine if it will help my Weber 38 to start up again. This regulator has its own return line. I'm trying to determine if I should keep the original type fuel filter with its return line or if it should be replaced with a basic inline filter since the regulator has a return line. I did see a comment that the filters return line is also a vapor vent and I have not learned if the Weber does that. I'm going to try to insert an image of what I think should work. If anyone is very knowledgeable about this, please let me know.
Thanks.

I use to have a Weber on mine for about 150K miles until EFI. The Weber didn’t need a pressure regulator. Just pump and filter like original.

Thanks,
Mine did work, but it went unused for about 3 months then wouldn't start. The fuel pump (mechanical type) seemed to be pumping almost nothing so I put on a new one. I just got a pressure gauge so I will get a battery back in it tomorrow and be able to check the pressure. The Weber info says it only works in the 2.5-4.5 pressure range (seems narrow) I'm very interested to see what my pressure actually is.

After 2 weeks mine would act out a little and not want to start easily either. I would drop maybe a teaspoon of fuel down its throat and that worked well. They don’t need much pressure.
