Cold Start Injector Fuel Pressure

I've got a 1987 fuel rail with cold start injector provisions. I'm going to be running a 1990+ speed density system that automatically enriches the cold start mixture. Would it be possible to run a fuel pressure gauge from the fitting from the deleted cold start injector? If so, does anyone know the thread count/pitch?

I too have the cold start setup and am switching to the 90-92 Speed Density system.
Can I just leave the CSI attached to the manifold and just have the injector connector disconnected?

Thanks,

Zepher,

Disconnecting the CS injector connector, or the Thermal Time Switch connector (big brass thing on the front of the intake manifold) will work, but it is even cleaner to pull the cold start fuse.
