Try maybe pressure washing ,maybe a radiator shop might help? Small drill bit? I would start with compressed air. Maybe some brake cleaner 1 1 Link to comment Share on other sites More sharing options...

Is there a possibility that there's a one way valve in there so the fuel can only exit? I haven't seen a 73 this close for almost 30 years so I'm just guessing. I don't recall my series 1 car having that enlarged end when I had the line off it a couple of years ago. Link to comment Share on other sites More sharing options...
Patcon Posted January 6, 2020 Share #51 Posted January 6, 2020 I believe they all have that. A remnant of the swaging process I was going to tag Jim but I don't know how to do it from my phone Link to comment Share on other sites More sharing options...
Captain Obvious Posted January 6, 2020 Share #52 Posted January 6, 2020 I'll second the above. All of them I've messed with look like that and there's no check valve. Just an orifice. I suspect your orifice is plugged with crap.* *Don't you just hate that? 1 Link to comment Share on other sites More sharing options...
