Every build needs the proper fueling. Sometimes it's just a set of injectors and a fuel pump booster, but to make real horsepower you need a real fuel system.

We have the answer for just about every build, from a 1999 Mustang GT making 600rwhp to a 2018 Mustang GT making 1300rwhp, and everything in between. 

We offer systems ranging from the entry/budget level that retain factory fuel rails and feed lines to complete fuel systems that come with all fuel lines, fittings, rails & more. 


Do you have a 2011-2017 Mustang GT and just want to support E85 with your low boost setup? Do you want to support 700rwhp now but want the ability to upgrade easily down the road for more horsepower? 

Our 2011-up Coyote Level 1 and Level 2 fuel systems are what you are looking for. They come with all parts needed for installation (including a billet fuel pump hat, fuel pumps, wiring & fuel line). CLICK HERE for more info.


Do you have a 2003-2004 Cobra and needing to support more than 600rwhp but not in need of a full system yet?

Our 99-04 Mustang Budget Return kits will handle about 750rwhp and retain your factory fuel rails and fuel feed line. Oh and they start at just $854.15 SHIPPED with the sale...


Check out the site for all of our fuel system options.
