    Rated 5 out of 5 by from Woke up our Suburban Could not be happier. Our Birb was sluggish and needed a wake up. I had read conflicting reviews about leaks etc. all I can say was mine was perfect, it was quick to install and gave no issues. I can see where if you were not carefull you could cross thread the fuel lines but that would be solely operator error. The difference in performance was night and day. If I was building another TBI this is the first mod I would make.
