I removed the filter & lines on my '54 235 years ago, don't recall why, and connected the line going to the head in the wrong hole (front/return).

Now I'm trying to put it in the right hole (rear/pressurized) but the fitting is the wrong size. I'd like to tee out of the pressurized hole to feed the head and the pressure gauge but I can't figure out the fittings/sizes/threads I need. Does anyone remember what these are? The pressure gauge line is really tiny and the head line is about the same size as the fuel line.

Thanks.
