FAST fuel rails
FAST fuel rails I am going to run the FAST LSXRT intake on my stroker 6.6 LQ4 and I am trying to pick out what fuel rails to run. I've read a few comments on here about FAST rails leaking. The billet rails that FAST sells for specifically for this intake look pretty good but i am gun shy, scared of buying a potential headache. Are FAST rails that bad or is it just 2 or 3 guys out of a hundred with a problem?

I know they don't look as cool but the factory truck ones fit rather nice, you have to cut
factory mount tabs off and create you're own mounting tabs, but they probably won't leak,
and some of the factory one's have the regulator as well.

The fast rails work. They have orb fittings for the ends so no issue there. The metal truck rail for gen4 truck intakes works well also. the nylon one can be a bit ugly and problematic
Id recommend either the gen4 stainless truck rail or their billet rails.
