Fuel Pressure Regulator

[johnono]

I think its had its chips, so iԚ´m gettin a new one.

Can i just clip each end closed and replace or is it going to be a prob with air in th pipes as i undo them?

also i was quoted 20 squid for a new one, but i think it may be a "happy price" just for me

what do i do lads

[Andy335Touring]

Do you mean the fuel pressure regulator ?

[johnono]

yup.

[Andy335Touring]

I've not changed one before but it looks easy enough.

Leave your car to stand over night so the fuel pressure drops.Pull off the vacum pipe,undo the fuel pipe but be ready with a rag to catch any spilt fuel,undo the two securing bolts and pull off.

There is an O ring that need replacing and i have a spare one if you want it ?

Or they are about 1.50p from the dealers.

As i say i've not changed one before so i'd wait for some one to confirm what i've said is correct.

[johnono]

nice one andy i have a price for a complete unit with rigs and things included, but thank u fella

i was thinking about using one of those Bag-lox thingys that u clamp frosties bags and other stuff closed with. if i stopped the fuel line with one of those, and had a cloth handy i should be alright shouldnt i?

iԚ´m going bmw tomorow, so ill ask them what itԚ´ll cost from them and see whos is cheapest vs. quality

i hope this solves the slow start up issues

[Andy335Touring]

Is that the fuel pressure related fault that was on a thread a while a go ?

Starts straight up if you prime the pump or if it has been running shortly before you start it again ?

Takes a few turns to fire up first thing in the morning ?

[johnono]

Exactomundo!

i have a 10 second dance with her every morning, and tbh its getting a little embarrasing now i do the prime also but its not really helping that much

and its pretty much consistent, if the car has been left an hour or more

[Andy335Touring]

Be interesting to see if a new reg' fixs it as mine is similar

[johnono]

someone said a leaky injector could be the cause of it also ( i bet it was you aswell )

[andyp]

just be careful as petrol will spray out as you release it for a second put a cloth over it as you take it off as petrol in the eyes burn and it dont taste very nice.

[johnono]

iԚ´ll be carefull

If you remove the fuel pump relay and start the car the fuel rail will depressurise leaving it safer to remove the FPR.

As you probably know it's held on with 2 M6 bolts a hose clip and a push fit for the manifold vacuum take off.

Getting one off is easy enough, but can be a sod to get back on.

The method I found to work for me was to locate the FPR in the fuel rail and put the M6 bolt in the hole closest to the windscreen, only a couple of turns though as it will raise the other mounting too far to get the bolt in.

Get the other M6 bolt in and tighten them down gradually swapping bolts after 2 turns, if you know what I mean.

This will walk the O ring into the fuel rail without snagging it up. I did mine this morning so it's fresh in my mind!

[johnono]

ive got one coming, for a score so ill be on that with gusto as soon as it lands! nice one for the tech help though bruvsys!!

[320Touring]

so you managed to track it down to that then?!nice one!

i'll catch ya on MSN laterz dude!

[johnono]

Easy Neily! Yeah! i got one coming and a new back hatch seal, so i got jobs on


found out about the brakes today iԚ´ll tell ya later

The easiest way to relive the fuel pressure is to start it up and pull out fuse 11. This will shut down the fuel pump and then the engine will cut out a few seconds later, Turn the ignition off and then remove the fuel filler cap just to release any back pressure in the tank.
Then when you pull the fuel hose off the regulator do it slowly and gravity should pull most of the remaining fuel in the injector rail back down into the tank.
And no smoking.

[johnono]

good tip martinaston fuse 11, wait for it to cut out, open filler

then as andy magic said, and i should have it sorted

[chu346]

Johnono, where have you been quoted Ԛ£20 for that regualtor, the cheapest i can find is Ԛ£40.

[Martinaston]

Johno if you have trouble with your O'ring a little vaseline will help.

[johnono]

chu, i got it from Otto at www.koed.dk

good peeps, but can be a bit shadey

martin... grease my ring with vaseline

[Martinaston]

Johno you and andy were talking about a thread about leaking injectors but i can't find it. Is it still on here?

P.S. not too much vaseline you have to have a
bit of friction to get the feel of it .

[johnono]

dirty bastard

ill look for the thread , see if i can find it
