Hi all,

I bought a Frank Weiss 5 stage dry sump pump and since I am in Europe and not familiar with the non Metric thread and connector I would like to know what kind of fittings these are!

The red one is an 16AN (feed to the pressure stage).

All the others? How is this blue fitting format called?

Those fittings have their origins in Aviation. AN (Army Navy) is a older standard not seen much on modern transport aircraft but it is very popular in auto racing. AN flared fittings are sized in 1/16ths inch, so a -8 would be a fitting for a 1/2 I.D flex line, -16 is a 1 inch line. I'm unable to identify the blue fitting from your pic.
You can google Aeroquip AN fittings for more info or check out this link to a more aircraft oreintated explanation of lines and fittings.

I know of the typical AN fitting with tha 37 degrees flare.

The blue line comes directly on the pump scavenge stages and was supplied with.

Thing is the pressure stage outlet has the same fitting but a tad smaller and I don't know how to search for them in order to buy one.

Looks like the scavenge sections use an oring boss radius going into the pump.
