I've always gotten both valves in fuel pump rebuild kits. Was the bag opened? It's a good idea to replace them.
Running low fuel pressure on a 2 stroke engine is an extremely bad idea. The lower the pressure, the hotter the engine will run to a point at which you will melt holes in the pistons if it gets bad enough.
Really... if the fuel pressure isn't correct... don't run the engine.
Fix that pump, ASAP.
