FiTech 36261 Go EFI 2x4 625 HP System, In-Tank Fuel Pump, Shiny

Dual Quad EFI made simple with the Go EFI 2×4 625HP with bright aluminum finish self-tuning system combined with the Go Fuel In-Tank Fuel Pump Module fuel delivery kit. This kit is a bolt-on for the most popular manifolds including the Edelbrock line of dual quad manifolds without any adapters! They fit and look like they belong there because they were designed to fit from the start. Our normally aspirated kits are good through 625hp but our Go EFI 2×4 Power Adder kit can handle you guys with the bigger cubes and roots superchargers. One throttle body handles all of the brains while the second holds four additional injectors and the IAC motor for idle stability. 

When it comes to converting to EFI, it’s important for the fuel pump to be installed in a cool area and what better place than in the gas tank itself. The pump is cooled by the fuel, it’s quieter plus there’s no chance of fuel starvation. To help ease the installation of an in-tank pump, this kit includes a new In-Tank Module assembly.

This universal billet assembly can be used on tanks with a depth of 6” to 15”. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.

The cut-to-fit bracket secures a 340 LPH pump capable of providing fuel to 600 horsepower engines. To ensure clean fuel is pulled into the pump, two sizes of sock/filters are provided, a standard 11 square-inch design as well as a large, 35 square-inch version.

Bolt-on two of these tough looking throttle bodies and drive your car as the system dials itself into the perfect calibration for all of your driving and weather conditions. If you decide you want to tune for more power or economy, the FiTech touch screen controller allows quick and easy on the fly adjustments at your fingertips!

These can also be used in cross ram and tunnel ram configurations. No boost with these, please! For boosted and high horsepower normally aspirated applications please see our Go EFI 2×4 Power Adder (Part #52130064).
