O2 Bung for EFI
 

This subject has been brought up numerous times but I can't find anything regarding Gil risers, I have Dry to Tip risers and now going from carb to EFI and need an O2 bung either welded, a spacer with an O2 already installed or new risers with it installed..... I prefer to use the spacer as I am not fond of destroying my risers or just getting new and selling what I have but if GIL doesn't make anything then I guess I have no choice, any help would be greatly appreciated.

Thanks

just have them welded into the risers,its no big deal for a welder.we just did 4 cmi headers today.and my gil pipes have had bungs in them for 9yrs.

Young performance I believe has an easy way . Use a step drill to make the hole, peen it , weld inner and outer together, then weld in the bung. Done.

I cut a 2" round hole through the outer pipe, tig welded a piece of stainless pipe in the hole to seal off the water, then drilled and welded in the bung to the inner pipe. Zero worries about leaks.

step drill the holes,outer pipe hole is the size of bung,then cut a step in bung to fit tightly into the inner pipes hole(I make it a tight press fit).then a simple tig weld.neat and clean.
