well i just finished what i think to be is buying all the parts to get this rx 7 running it had an engine fire but when i was pulling it apart there was this thing that had 4 hoses to it what was this and any 1 know some good hose diagrams because i haev no idea really where any of the hoses go

 

take some pics, it might help us identify

 

sounds like the OMP spider. the vacuum lines connect to each of the 4 oil injectors. 2 on the LIM, 2 on the rotor housings (on turbo models at least)
