Some help with the fuel system !!!

[Master Chief]

Hi to all!
I was wondering if anyone here could help me out with something.
I have a Clio 172, and as some of you know i have a NOS kit on it.
Anyway i need some help uderstandig what type of fuel system have renault installed on this car.
For example, what type of fuel pump, what type of regulator and so on.
I saw on earlyer 172 models, that they have a fuel pressure regulator attached to the fuel rail.
On my modesl the fuel regulator is not there.
Allso on my model there is no return line from the fuel rail.
How is the fuell pressure regulated on this model ?
I really need to know for exapmle where and if the is a return fuel line.

Meaby some blue prints of the system could help!
Can anyone get me some ?
I know there was a guy here who said he has all the blue prints of the car on a factory cd .

Pleaseee Help !
Thanks.

can anyone tell me how much the fuell pressure should be?
on a stock 172 clio?

off the top of my head its somewhere around 3.5-4bar

If your using a clio 172 phase 2 (facelift) then fuel pressure will be regulated in tank (so no return line).

As fred said, around 3.5 bar.
