Whether upgrading for additional fuel delivery needs, to run upgraded fuel lines, or to simply clean up your engine bay, ACUiTY's K-Series High-Flow Fuel Rail is the most versatile and refined solution available. With it's 1/8 NPT port on top, -8 o-ring boss (ORB) ports on both ends and another -8 ORB port located at the middle of the rail, there are a variety of ways you can set the rail up for your car (see "Fitment Info" for application-specific fitting requirements). Each rail is constructed from 6061-T6 aluminum and has a satin-texture, anodized finish with laser-etched technical info and logos. 

Among the rails' other features are countersunk mounting screw holes and supplied class 10.9+ hardware to replace the OEM studs. Each rail is also supplied with a stainless steel 1/8 NPT plug in case a top-mounted fuel pressure gauge is used. The end locations for the -8 ORB ports have been specifically machined to help reduce the likelihood of wrench damage to the rail's cosmetic finish during installation. As an added bonus rarely found on aftermarket rails, the rail allows the end-user to retain the OEM injector clips if you wish, just for some added peace of mind.

Tons of possible configurations (using optional fittings, sold separately). See the "Fitment Info" tab for a list of fittings by vehicle and configuration.

Side-feed for OEM fuel lines on many vehicles:

Center-feed using a -6AN line: 

Return setup with -6AN line for k-swaps and high horsepower applications:

Design retains OEM injector mounting clips for extra peace of mind:

Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart. It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!
