Power washer chemical connection broke

Craftsman Power Washer Model 580.752310.
The connection for the chemical (soap dispensing) fitting broke off flush with the pump block. This is where I connect the plastic tubing to the washing solution.
Any ideas on how to remove the broken section in the pump body?
Attached is a parts exploded view. But to honest I can't clearly identify which assembly I need. The "J" or the "G"

I determined it's the "G" assembly in the parts list. and I found it available for about $17 on line. Before ordering new part I'd like to get the old out first.
Any suggestions? Maybe an easy-out screw extractor? Possible drilling it out. Any hints on how bets to do it?

Went to the Sears site and I guess this was a problem as the new ones are brass.
I would not try drilling it out. Too easy to screw up the threads.
I am not sure you can get a screw extractor that big. Also it may give an outward force and since the part is plastic it would expand it making it tighter.

Looks like it is plastic.
I would try to cut a notch at the top with a knife or pick. Then with a flat screwdriver and a hammer back it out.
Better yet a notch on either side and a screwdriver of the correct width and unscrew it.
If you do not have a driver of the correct width then cut a piece of metal to the correct width and use that as a screwdriver

It's definitely metal. And yes I found out it's the weak link of this machine.

It does not look like a totally clean break so find a indent and try backing it out with a small cold chisel.

Good idea. I'll spray a little wd40 or PB blaster. That might help.

Manden,

Took your advice. I used a small screwdriver. Came out very smoothly.
