I have been messing with this for a week & dont know what else to do.I am trying to install a flo-thru manifold on the end of the fuel rail on my 2002 corvette. I have tried 3 different ones and everyone leaks at the plug in the port that im not using. What can i do to fix this? We have our first show this weekend & im beginning to think i cant fix this.

 

what kind of plug is it? is it pipe or an? if its pipe did you use a sealer? if its a an plug does it need a oring or a teflon washer?

 

Its a AN manifold and i put the teflon paste on it,but still leaks.

 

i would use a plug that uses a oring or washer for a sealer instead of paste they say that ans dont require paste because of the flare seal

 

Are you tightening the **** out of the unused port plug? If nothing else use the paste and let it sit/setup before pressurizing the line.

 

I bet its an An adapter with an NPT port plug .

1/8-27 npt plug and some teflon tape should handle it .

 

Yes,it has the npt plugs.

 

Thanks for the help guys. Went and got a brass plug used it instead of the one that came with it. No more leak. Thanks again.
