VR6 fuel pressure regulator and piping.

[aclwalker 3]

I'm wanting to replace the vacuum hose on my fuel pressure regulator and ETKA says that the pipe length should be 175mm ("cut to 175mm"), but this seems quite long to me. My existing one is nowhere near as long as that.

 

Does this sound right? The reason why I ask is that I found some threads for the G60 which said that the length is critical.

 

Do I have to use VW pipe or will Halford's stuff be alright?

 

Also, any cheap suppliers for a new fuel pressure regulator? I think mine is suspect (and I also chewed it up a bit in the past trying to get it off to inspect it. Never managed to get it out in the end!).

 

Finally, the pipe from my existing fuel pressure regulator sticks out horizontally to the right, whereas I've seen other Corrado pictures where it points more upwards, maybe like 10 past the hour.

 

Does the angle of this vacuum pipe have any bearing on its function?
