fuel leak under intake manifold - 83 chevy van

[DungBeetle]

I thought it was the injector pump, so I had it pulled and rebuilt, but the leak is still there. It doesn't seem to leak until after I stop the engine, but that may be coincidental. The fuel puddles up in the back of the block just in front of the vacuum pump. I assume it must be one of the injector lines, or an input hose to the injector pump. Has anyone else run into a problem like this?

The hose in between the injection pump and the fuel filter, any rubber in between the fuel filter housing and a hard line, all can be culprits.
