Fuel pressure regulator
Hi all
I was just wondering what/if anything would happen if i removed/bypassed the fuel pressure regulator since i'm pretty sure that is what i causing my intermittent issue with accelerating under load and the lack of power.

Re: Fuel pressure regulator
You will blow your injectors up!
I have a brand new one you can try if you want it. I can post it tomorrow to you. Try it out. If you want to keep it, pay me the £25 I paid for it, or, send it back if it doesn't fix your problem.

Re: Fuel pressure regulator
It doesn't look the same James mine doesn't have any holes for fixing bolts, just a straight "in" and "out" it's not attached to anything other than those for the inlet/outlet.

Re: Fuel pressure regulator
I think that is just a non-return valve. Your regulator is on the end of your fuel rail. It is vacuum powered.

Re: Fuel pressure regulator
Apologies Shane, I've just checked the parts catalogue and the pressure regulator that I have might be for the later 1.7 cars, not the 2.0 cars. I will dig it out tomorrow and see which I have
Your fuel pressure regulator is still on the end of your fuel rail but the part number is 3464447. Item 5 in this picture:

Re: Fuel pressure regulator
Here's the valve you were looking at first. I suppose it would be worth checking to see if it still works as a non-return valve while you have the fuel pressure regulator off if you do change it. I think it's purpose is to keep petrol available to the engine for easier starting.

Re: Fuel pressure regulator
Well don't i feel like a burke... I thought it was that what i had circled even a mate who is big into mechanics told me it was that....Shows what he knows eh !
James thank you once again for going the extra mile to explain this to me, Now i understand... I Would have been knackered otherwise.
Just to clarify that the non return valve is fine it's never had a problem starting ever...
So it looks like i'm going to have to get to grips with this is.. Is it a particularly difficult job getting to the FPR or is it just a case of taking the bank of four pipes (Not sure of the technical term) of to get to the injectors etc...

Re: Fuel pressure regulator
It's easy peasy to change it just depends whether or not you can get it off with the larger 2.0 manifold in place. You shouldn't have to take the fuel rail off or any injectors as it is just bolted on the end of the rail.
Two bolts, vacuum pipe, some fuel will spill.

Re: Fuel pressure regulator
On our site, it mentions that is does non-return and damping to compensate for the injectors opening:
viewtopic.php?t=11172
Just read the French site (via Google translate) and it actually does some vibration damping in the return line to avoid the noise of the injectors reaching the cabin along with its more obvious function!

So, I've learnt something tonight too!
