Vintage air compressor ID

[bustermathis]

I have this vintage air compressor it wont build pressure and i cant find any information on it. I can find information on similar ones but not with the v twin cylinder configuration like this one. I also need recommendations on how to get or make another transfer tube. The metal tubing that goes from both cylinders back to the pressure gauge as it has leaks in it.

make another transfer tube

easier made than explained here , but what is the OD of the existing tube? 1/2" or 5/8" ???
soft copper tube would be where I started

Just with a tee to connect the two cylinders? See how it is in the picture?

Yes, just don’t smash it as much this time.
