Ok Im getting my fuel for the n20 system from the shrader valve. Im wanting to take my noids off and get them looked at and/or serviced. I need to know the best way to be able to stop fuel from leaking when I remove the fuel noid. Can I just cap where the shrader was or do I have to buy a whole new shrader valve. If it makes a difference coming off the shrader I have a single hole purge/gauge adapter and hooked to it is a FPSS and then obviously a hose and then the fuel noid. Thanks for the help!

 

As long as the valve stem is still in there, you should be ok.

 

The valve stem was removed when the n20 kit was installed!

 

ive read that some ppl have capped it with just that little cover it worked. If I couldnt find the actual little valve to stab back in there, I would try to get ahold of a metal screw cap (like the billet ones for wheels, or somthing like that)

 

Gm says not to reuse them once they are taken out and it doesnt matter anyway becuase I dont have the original one. The parts store sell 1/8 npt or 4an I cant remember which one it is-I think its 4an. The thing Im worried about capping it is what pressure do I need tha cap to withstand!

 

Just go to GM and buy a new core for it and put that in there. Can't be THAT expensive.

 

I found out I can just us a 4an cap! Thanks for the help!
