My memory really sucks and I'm not finding a good picture to reference.

I thought it was larger port was supply and smaller port was return.

See my picture below.

It's a 1974 CIS.

No arrows, even looking at used units on eBay etc.

I think I may have my supply/return reversed, this is how it's plumbed currently. From what I can sort of tell on fuel diagrams, looks like the regulator is at the return hose side.

Anyone that can help confirm would be appreciated.
