need your help....dripping injectors

All of a suddenthe 2 injectors on my '86 Blazer 2.8 started dripping. There is a nice conical spray when you rev it up but I can see almost a stream dropping down from the center of the injectors. At idle there is very little spray and mostly drips. If I energize the fuel pump test connector with the return line pinched off there is no leakage from the injectors or anywhere else, dead head pressure is 18 psi. New fuel pump, new inline filter, new o rings, gaskets and injector filters, new pressure regulator diaphram, pressure test is within specs, no visible leakage anywhere, no restriction in return line and it has thrown no codes. It's hard to believe that both injectors would malfunction at the same time so I'm a little hesitant to spend the money on 2 new ones until i've exhausted all other possibilities. Thanks in advance for any and all help given...my back is killing me from bending over this thing...lol

RE: need your help....dripping injectors

something is failing to hold back from what it sounds like i would put my money on having to replace them unless someone knows of something better to do.
