I have already bypassed this but does anyone know if there is a tech write up that explains how to fully remove all the components to it?

PFPR - that's it!

PRVR?? If so, just follow the lines to the solenoid by the battery and remove it. Remove the arch liner then the small pressure resevoir that the other lines from the solenoid go to.

That's it done.

Whats the good of removing it? any downsides?

Not sure what the good is, but since I removed mine it runs a little rough at idle of the first 10 seconds.

 

The PRVR helps with cold starts.

 

My car starts first time on the button winter or summer, the fact that I snapped the canister than stores the extra air required was the reason i removed mine.

Cut & Paste:

 

 

PVPR is pressure regulator vacuum relief system.

It's designed to boost fuel pressure for starting or if fuel temp > a certain value.

It works by switching the FPR's vacuum signal between manifold and a surge tank that is held at max boost pressure.

Removing it saves some weight if you remove the solenoid and tank, and also simplifies the vacuum piping a bit. Also, it's less parts to go wrong / split on this crucial line.

Removing it has the possible downside that the car may be harder to start, and you loose the (very little) protection it gives for the very unlikely hot fuel condition.

I've had it off mine for ages and had no hassle what so ever starting it.

To be honest.. removing this to save weight is not really something you need to worry about, the tank is plastic. So the total weight removed is problably less than a lb :(.

The heaviest thing is probably the bracket that holds the tank :).

 

However if you just want everything out of the car that you don't need then yep go for it ;).

So I take it the electronic connectors are then just left to dangle?

Yep, just tape it up.

cool - cheers.
