I had the same trouble. It took an impact wrench. We tried cheater bars and everything for about 2 hours and then finally got out the impact wrench. Used two tanks of air but we got it off.

The plug is easy and the thing to do if you're just doing the MP-8. If you plan to stack then you should do the shims. But we were running 125 psi on an impact rated for 1000 ft/lbs in reverse and we used about 5 gallons of air. Some must have loc-tite or something because it was hell to get off. They're only supposed to be torqued to 50 ft/lbs from the factory lol.

as you can see, threading is different... did they send wrong nut?

I'm pretty sure that nut was used to hold the valve while in the vice so as not to damage the threading. That's its only use, so I guess you don't have to worry about it or you can get a new nut but I don't remember having that problem. Be careful with that o-ring too. Mine broke when I was putting the valve back in the fuel rail.

It should be the same threads. You got the wrong one if it isnt. You do need it to pull that valve apart. Might have to find one that will work.

Yes you need the nut. You use it to pull the valve apart, properly. You do not want to mess that thing up. Contact TS about getting the right one, or go to Home Depot.

Guess I'd better check my nutz...don't want to have that problem. Did they say if there was a time frame or a specific batch that got sent out with the bad nutz? Can I tell by looking at the nut, or do I have to first remove the valve and try it?
