blackbird and busa injectors

[Maj]

Injectors are better tested with a 9 v battery , get a suitable injector plug from a wreckers and a 9v battery connector and a small toggle switch from dick smith or tandy, and be real carefull of fuel and sparks.
If your not sure about replicating your fuel system on the bench to test take then to a injector specialist for testing or if you have a running engine big injectors will not run on an otherwise std system
