🔌 Holley LS Hi-Flow EFI Fuel Rail 534-209, Black Review

Excellent quality as with most Holley products but some LS engines require an additional kit depending on the injectors. not happy with the additional $42 for the install kit.

Bought to replace a cheaper fuel rail I bought from Revain which was leaking like a garden hose. This system fitted and worked right from the start with no leaks. My only advice is to get a pair of ORB #8 connectors if you don't have full flow hose routing (front and back).

Good rails. Got her working on my high injector TBSS shot but it wasn't easy either way. Started many times and seen many leaks and then made new mounts again. These rails are very good. Comes with perfect holly box and detailed instructions with multiple diagrams on how to fill it with fuel.

Does not fit stock LS3 Trailblazer stainless steel intake manifold with factory short injectors. The brackets included in the kit allow the installation of medium and high height nozzles. I was disappointed when I realized I either had to make my own mounts or not use the fuel rails.
