LB7: fuel rail plug lb7?

[turbospoolindmax]

I installed fuel rail plug in my 04.5 lly with efi live and I was really impressed by the extra fuel it gave me and I was talkin to my buddy with an lb7 and he was wondering if they make a plug for an lb7 and I looked but I couldn't see where u could put a plug on it so I was wondering if u can put a plug in and if so where? im not familiar with an lb7

It goes on the return line by the y-bridge.

Or you can weld the banjo bolt shut.

Anyone with an lb7 have one of these installed with feedback ?

I welded mine shut, but I never had issues with it popping open previously. I think LB7's don't have that issue as much.

X2 haven't heard of many people needing them on the lb7 models as vs the lly, lbz, and lmm models!

LB7's tend to not pop so long asyou keep the rail pressure down under 200MPA. And the stock rail pressure sensor is only good to 200 MPA after it is rescaled(in stock tuning it is only good to 180MPA, and if you go over it will skyrocket and pop the valve open. if you don't have a valve it will crack an injector).

I shimmed mine with couple m4 washers.
