Master cylinder supposed to do this?

[Hubnut]

Got a new master cylinder for my 1991 K5. Routed hosed from the outputs into the reservoirs to bench bleed it. When I pushed the piston in, fluid would spurt out of the closest reservior hole (the one in at the bottom of the reservoir). Tried it with my old one to see if this might be normal--same deal. Is this some kind of funky Chevy design. This has never happened to me before. Typically fluid is drawn from the reservoir throught he output ports on the side. I mean it GUSHES up from the reservoir. Thanks for any help. I know that sometimes new parts can be broken.

a stream up from bottom of master is o.k. on these. just push slow and make little mess.

I've only done two... but I have always just bled them in the truck.

Thanks sweetK30. I've confirmed that this is normal for this master cylinder. Weird.
