OK,I give up. I have a 85 305 TPI/700r4 Camaro. I need to replace fuel pressure regulator diaphram and cannot find correct tork or whatever it is style socket to remove the top of the regulator. They look like a small tork with a little stem or nipple in the center. Anyone know what size or what type of tool is needed to remove this regulator cover?

 

"Security or anti-tamper" screws. The tool set can be found at autozone or most other auto parts stores.... Looks like the old style allen wrench "L" shaped wrenches. Didnt cost too much. I just went through this a couple of weeks ago. LOL

Good luck, I hope this helps.

 

they are just tamper proof torx screws, can't remember what size off the top of my head..

 

Thanks for your replys. I found it at Ace. #10 tamper proof tork

 

were you able to buy just the one you needed? I ask because I need to finish reassembling mine pretty soon and I have an entire set of tamper proof snap-on bits but I've managed to break my 10 and don't have access to a snap-on dealer at the moment to get it replaced..

 

Yes ,Ace had them seperate or in a set.
