For 1988-2006 Cherokee XJ Wrangler TJ YJ Billet Aluminum Performance Fuel Rail Kit

Turn key ready to install in most cases.

Depending on your year of vehicle 4.0, you may or may not have a regulator built into the rails with "in and out quick connect fittings". This aluminum rail has one "in" provision. If yours has "2" then see below:

The stock "rail" regulator is not very reliable. Fuel pressure regulating for motor is primarily handled by internal pump regulator in tank. On my 4.0L the stock tank fuel regulator actually provides near perfect line pressure without the need of an additional redundant rail regulator.

However you can easily add a early 2000’s GM corvette regulator/filter combo in the fuel line near rail if you wanted to add an additional filter/reg. I also sell all the fittings for that as well. That unit is nice because it’s a filter as well.

You can use upgraded EV14 injectors or stock injectors. However if you decide to upgrade to EV14, you will have to get your own injector electrical connections. No injectors or manifold are included. This rail kit allows you to utilize your stock injectors and your own manifold.
