hdi fuel filter

[mjb]

So how do you get at it? The Golf had a cap that came off with no problem, but the hdi90's doesn't look like it should - nowhere to grip. Do I need to put a spanner on the hexagonal bit at the top?

[Doggy]

Yes, carefully I gave up trying to undo the one on my HDi 90 after some gorilla tightened it up.

That was bloody difficult for such a simple job. Handy hints:

1. Take the quick-release connections off the top first
2. Use a 22mm socket - six sided - AND turn the fuel connections at the same time to distribute the pressure
3. The O-ring is at the top of the housing. Hard to spot.
4. Keep the bumpy ring
5. Give yourself plenty of time. It's an arse to get the lid back on

i did that on mine and snapped the pipe off later realised you have to press it down as well as turn

Buy a new housing AND filter - that's my top tip

The housing is 10% the cost of the car when bought from a factor!

I thought they were £15.00? plus the filter cartridge.

So many people snap them it could leave you stranded unable to go fetch another one

Whatever you do,DONT apply pressure on the 2top tubes!!!
They snap REALLY REALLY easy. Ive done it twice now. Especially when theyre warm.
Best way :- WD40 (lots!), and 22mm socket as the guy above says.

The lid on mine was threatening to round itself off unless I put pressure on the hose connections... Guess it's just a lose-lose situation on these things then

One of my pipes came off when doing the filter, but upon closer inspection it appears someone had glued it back on before
As it was a few weeks before my holiday down to Cornwall I played safe and bought a new housing
I think i've still got the old one with repaired pipe and brand new fuel filter in shed

I just popped the one side of mine off and this thought just went through my head "Scotty your going to break this and you wont be going on holidays"

Needless to say the engine cover has just gone back on.

upto now ive never had aproblem changing the filters on hdis,
its an easy job, once the pipes have been popped of the lid comes off easy,

I got the left pipe off pretty easy but the right one looks a bit more awkward and i dont fancy being car less over the bank hol weekend, once we get back wether permitting i'll change it plus oil and oil filter... i popped a new air filter in today and the car seem to run better... Think i'm going round the twist cos surely a new air filter cant make it that much better? unless it wasn't changed at the last service when it says it was?

this is from a 407 but still the hdi, does the 406 look like this

[scotty73]

No trem where you got PUSH thats where the pipes come down from, think it's the same other than that.

The 407 looks a more sturdy setup to me.
