Stewart vacuum fuel pump question

[WillC]

I'm helping a friend with his Stewart vacuum fuel pump. I cant find the right size fitting for the fuel inlet. Anything I try is either to big or to small. All the other holes are 1/8 and 3/8. But the fuel port is an odd size. Anyone know what size it is and where I can find it? Thank you.

Vacuum fuel pumps were not offered for the early Ford V8's maybe Ford Y blocks.

Vacuum fuel pumps used on 52'-53' Mercurys

Is it the flexible body to pump line. If so check with early Ford parts supplier.

Some pumps used 1/2"-20 fittings.
