info needed on fuel regulator v8 disco

hi could someone please explain what would happen or symptoms if the vaccume hose that connects to the fuel pressure regulater is disconnected as i found this had been done on a v8 disc i recently purchased,i have now reconnected it and i think its more responsive,

you answered your own question,,,dont you think???

































































(it alters reg pressure according to engine load)

well i said i think its more responsive but not sure as i dont have it on the road yet as just getting it ready for mot. so i just wanted to know what will have been happening if it was left unconnected. is it flat .would it be worse on mpg. will it run uneven ect . basically would it run poor. as like i say have not driven it yet on road as only just purchased it so i wouldent really know what it was like b4 i reconnected it. other wise i wouldent be asking the question

dont see where you said any of that in your first post to be honest....but hey you now know

This seems to describe it Fuel pressure regulator

From RAVE:



If you haven't got a copy of RAVE for your vehicle, look for a download and get it, it covers everything.

Thankyou lister diesel

strangely mine runs better disconnected. If I connect then putting the gear selector (auto) into D etc, drops the revs to nearly 300 and it rumbles away till either stalls or revs up to 2000 then steps down, if I put it in N before stalling.
