Done. It was that brown plastic socket for the three prong electric connector. A little gentle persuasion and it was out. I put in the new plastic one. All is good - well not really. I just finished reading gxsr's thread about removing the ALDA and realized there's supposed to be an o-ring under the shut off valve. There wasn't on the old one and there certainly isn't on the one I just installed.
Oh well. It wasn't too bad. BTW, I didn't remove the ALDA completely I just pushed it off enough to allow access to the rear screw. My ALDA won't come out completely unless I remove those pesky injector lines.
I paid $58 for the valve. Fastlane has two different plastic models, one is $20 and the other is $45. I hope I got the $45 dollar one
