After rebuilding the Fuel Pressure Regulator in my daughter's 2.8 '86 GT, the car will start, idle at 2000 RPM, then die when it goes into closed-loop. It is running very rich.
I want to disconnect the Cold Start Injector's fuel line at the fuel rail. What plugs do I need for the fuel line and the port in the fuel rail?

To plug the hole on the fuel rail you will need an oil pan bolt. I believe it is the same size. When I did mine I just dug into my bolt can till I found one that fit.

What about capping the fuel line? If the CSI is stuck open, there would be a vacuum leak in the lower intake manifold.

pinch/weld the tube shut.

I thought about just pinching the line off without disconnecting it at all. But I would like to cap it and plug the fuel rail temporarily to see if it solves the flooding issue. If the flooding went away, I would just leave the line and rail capped/plugged.

the hole in the fuel rail is M12-1.75, remove the line coming off of the rail, install bolt. done.
the injector is #8 machine screw iirc.

Unscrew The Fitting That Goes Into The Fuel Rail. Take It To The Parts Store And Get An Oil Drain Plug The Same Size. Screw It In The Hole And Your Done.

That still leaves the line to the CSI open and a vacuum leak if the CSI is stuck open, right?

pinch the line off with a vise grips and bent it over or braze the end shut.
Or pull the CSI and plug the hole with an expandable frost plug.

You could just get a vacuum port cap and put it on the line from the injector. Even if the injector is stuck open, I doubt it would be enough of a vacuum leak to make much difference. ------------------
