Questions & Answers

Fitech fuel injection system up to 400 HP... use mechanical fuel pump?

Asked by: RonJr
This kit uses your existing carbureted fuel pump and fuel lines to deliver the fuel to the Command Center which is mounted in the engine compartment.

I have a 305 Chevy V8 from a 1988 Truck. Will this work on it. Thank you.

Asked by: JesusR
The 30003 will work for your application if you are using a square bore intake 4150 base footprint. Now, the pump will have to be upgraded to at least a 255 LPH size pump whether it’s a frame-mounted or in the tank setup. Both fuel setups require a return line back to the tank, last will be the stock ignition if there’s no vacuum advance or it has a 5 pin weather pack connection in place your going to have to go with a later version HEI to have functioning advancement since the earlier styles used the ECU to advance timing.

I notice that on someone elses post that you stated that a person could use an existing carburated fuel pump. So my question is, how much fuel psi is needed to operate properly since most carburated fuel pumps are low pressure?

Asked by: jackyl2rock
This is out or the Instruction Manual Remember that your system will be running at 58 PSI so consult a professional if you are not certain about this portion of your installation. Fitech does not recommend aluminum fuel lines EVER! Or you can use the supplied EFI high pressure fuel hose that is supplied in your Fuel Delivery Kit.

Asked by: Solomon
If you are considering Nitrous or any other power adder in the futur I would recommend this kit because it will have additional timing control when using the nitrous: https://www.eastwood.com/fitech-go-efi-4-600-hp-efi-system-power-adder-matte-black-finish-30004.html

I have a 72 534 ci ford industrial engine in a gillig school bus.there is a holley 4 barrel on it this time.not real happy with it.the engine has the governor disconnected. Does this work on engines this large.

Asked by: Knightrider
This will work on his large Cubic Inch engine.  Engine discplacement is one of the parameters you will enter when going through the controller.  This particular kit will work if your engine produces between 150-400 HP.  If your engine makes more then 400HP I would reccomend the east street EFI EW#22162
