Why switch to top feed?
– OEM style side feed injectors can be problematic, are difficult to install, and flow rate choices are limited.
– With a top feed fuel rail you have the ability to use a variety of different brands, and flow rates to accommodate your needs.
– Top feed fuel injectors are less expensive and more readily available when, or if, you need to upgrade.
What else is needed for install?
You will need an external fuel pressure regulator of your choice, and some fuel line & fittings. THATS IT!
