V70 XC AWD 1999 - fuel pressure regulator location pls?

[Ozzyosborne]

Hi all! Newbie here, thank you for letting me join! After many wasted hours trying to find the fuel pressure regulator I thought I'd ask you experts :-)
I'm trying to get my 1999 cross country to stage 0 so I can go a head with adding the Td04hl-16T to her with a map. The reason I'm asking the location for the fpr is I have a working fuel pump, have fitted a new filter and I'm still losing pressure to the fuel rail within a matter of minutes? I've checked the sparks for a leaking injector and all seems fine? If I prime the pump twice before starting she fires straight up? Performance is lacking too! I have a V70 2.4 as well (170bhp) and she kicks the XC's arse! Which I know shouldn't be! Any ideas pls? Thanks in advance! - Simon.

Usually the fuel pressure regulator is located down the back of the engine on the drivers side just above the engine subframe.
