Great Product, fits OE intake perfectly

By geoff g on September 2, 2020 | Verified Owner

I installed these rails on my OE style LS truck intake. (6.0 Lq4) and they fit perfectly. I used 6AN line coming in, so i had to order a reducer from the 8AN rails to the 6AN line. I used a 45 deg 6AN fitting for the main line coming in. 2- 90 deg 6AN fittings for the crossover line to the other rail. 1- male 8AN ORB o-ring plug for the end rail. This was used for a returnless style fuel system. Rails came with different mounting brackets, the paperwork provided shows you which ones to use for your particular setup. They bolted right on with no modifications or hassle. Great overall outcome.

10 out of 10 would recommend!
