At ZZPerformance, we have always prided ourselves in developing cutting edge cost effective products. This means staying competitive not only in terms of price but in giving customers what they want. Based on customer request we have introduced a new low cost fuel rail alternative for those running intercoolers. These fuel rails utilize modified stock components and allow the blower to be raised without interference with the fuel rails. Even better is that they boast many advantages over similar rails in our market.

Determine what style rail that you will need. If you have a return style Series II engine then you will select the L67 style rail. If you have a 2004+ Grand Prix(only) with the Series III returnless style fuel system then you will need the L32 style rail. If you have a L67 return style fuel system car with a Gen5 blower, you will still need to purchase the L67 style rail. We now have an option for our L36 Supercharger kit as well, if you have this kit that has a modified L67 intake manifold with bungs added, then you will chose the L36 Supercharger Kit option. Fittings are -6AN. 

  1. ZZP rails are not brazed like our competitor's rails, instead we use a tig welder. What this means is that even if you bend the rails, they won't crack or leak. This method is stronger and when working with a fuel system we feel it's best not to take any chances.
  2. ZZP rails are powdercoated. Our competitor spray paints their rails. Powdercoating ensures and show quality, long lasting look.
  3. ZZP rails are made with a jig and tested for a variety of configurations. They will fit right the first time, without having to bend or adjust them.
  4. ZZP rails use a braided line. Our competitors use rubber line which violates NHRA rules for having a maximum of 12" rubber fuel hose under the hood.

You will be reusing your factory fuel pressure regulator.

New version works with all intercoolers or without an intercooler. No need to remove the blower to install or remove the fuel rails.

If you are piecing together a ZZP L36 supercharger kit that will not require you to swap your cylinder heads, you will need the following items:

This does not make a complete kit, these are only for the people that need 1 or more of the main custom items.

Fuel rails

They have problem with leaks

United States United States


I bought these turds for my 98 GTP, received no instructions, but pieced everything together with the picture in the description. The mounts did not line up, the fuel pressure regulator hole had to be bored out to fit, the fuel line hookups were BOTH too big to fit the lines and the overall alignment Is so poor that even with new injector o-rings I’m spraying fuel all over my engine bay and the braided line won’t reach without bending the rail. 57/10 do not recommend. They do look good though


Small issues

1. Does not come with any way to show how it goes together and they have a new design. So it took a bit to figure out. 2. Its a tight fit between each stud you have to have it lvl or it wont go on. 3. Injector **** in center of the rail feel a tad off so each time I put em on I had to center it while pushing it on. 4. Fuel pressure regulator would not go on without upsurd pressure aka a hammer. Overall it works but I feel like for the price I should not have to deal with all these small issues and wish they update the picture so people know what they are buying Pros. Looks nice, once together actually functions nicely, allows space for the intercooler

New style modded rails

I like the finish of the new rails. They’re nice on the eyes and are tig welded which is great cause you’ll need to bend the brackets a touch to fit. Great product from my favorite guys at zzp!

Modified fuel rails

I just bought these rails 2 weeks ago and haven't installed them yet, because I'm piecing together the L36 m90 supercharger kit, and they look like it would be very simple to install them.
