I think this is what you are looking for:



The fuel manifold, which distributes the fuel to the injectors, incorporates the seats for the injectors and the differential pressure regulator.
The fuel supply and return are carried out through rapid attachment.
The pressure regulator ensures the right fuel supply pressure in ratio to the air chamber pressure.

1, Fuel manifold
2, Injector
3, Differential pressure regulator
4, Air pipe
5, Connector for fuel supply quick coupling
6, Connector for fuel return quick coupling to tank

[FONT=&quot]Neilship, thank you so much for the quick and detailed reply. I needed this info, because I bought a power box from Bonalume to attach it to my tjet 120 hp and it comes with a bigger fuel pressure regulator. [/FONT][FONT=&quot]After the initial inspection of the engine, I realized I will never be able to install it myself and went to my mechanic to do the right job. The kit came with no installation guide.

It took almost 30 minutes to just install the fuel pressure regulator.

[FONT=&quot]He connected the two pairs of harnesses (petrol and pressure) and connected the the two electric wires as follows: black wire to an earth point in the engine bay and the red wire was connected to a wire that turns on with ignition and off with idle. When we turn on the ignition the device's two lights turns on with one steady light and one is flashing. When we turn ignition off the lights turn off.[/FONT][FONT=&quot][/FONT]​

[FONT=&quot]I drove the car but did not notice any observable power increase, because the attached sheet to the kit says it acquires 5% for every hour driven.[/FONT][FONT=&quot][/FONT]​

[FONT=&quot] [/FONT]​

[FONT=&quot]This is what I have done.

Is this what you got? http://www.bonalume.com/catalogo_en/kit_engines_tjet_.html

It says available for the T-Jet 155hp. Is it right for your car?

 

[kmhbravo]

Yes this is what I got. they sell both the 120 and the 155. It is for the tjet 120 because it is written on the body of the device and the instructions also say so

Cheers

(Sorry for reviving this old thread)

Can anybody tell me if the fuel pressure regulator is a separate replaceable part from the fuel rail? For the t-jet engines.

 

[Graf]

Yes,
Its a different part.
I've replace the original 3.5 BAR to 4 BAR.

 

[aurick86]

Thank you for the quick answer, in the mean time i already went out, removed the complete injector rail.. and pressure tested the regulator..seems to be fine.

Can you, by any chance post the 4 bar pressure regulator part number? or how you got to it.

Sure,
