405 Fuel filter change help

G`day chaps,
Being a fuel filter change virgin, I wonder if you could advise?

Haynes manual is total ***
It`s a 1.9 diesel (non-turbo), with the newer filter type, integrated temp
sensor, accessed by
the four hex bolts atop.
I want to do this properly, having heard horror stories of non-starters
following no/incorrect bleeding sequence.
Manual says to open bleed screw.....Where ?..... front ?, back?...which line
?
Is this the water bleed or fuel bleed or both ??
The only screw? I see is at the rear, bugger to get to, plastic witha
circlip on.
Also the long black pipe draped down the front of the motor, whats this ??

Any help greatly appreciated.
Andy.

 

I Andy,

No, should be on the front.

It is the drain pipe, which is connected to the drain screw.

This is my sequence for my '93 205, same equipment as you 405 :
0/ Opening the drain screw flushes some fuel out through the drain pipe, but
may cause a leak on the screw itself, that's is the reason why I don't do
it.
1/ Remove the 4 BTR screws.
2/ Open the filter housing, be careful with the seal. A few fuel may escape
from the top of the filter housing, don't care.
3/ Change filter.
4/ Fit the filter housing's top, secure screws.
5/ Using the little black priming pump (should be on your left when
performing a fuel filter change), pump until it becomes pretty hard - but
not too much, it may destroy the black pump. Hint : after pumping 5-6 times
you should hear the "pfffffff" sound of air being chased from the fuel
circuit.
6/ Attempt to start. If it stalls after some seconds, you have missed the
priming procedure, go to point 5 and try again.
7/ If you're at this point, you can drive the myth once again

Thanks for the reply G.T.,

Just the one question.....
Where exactly is this bleed screw, is it metal, plastic, front, back or side
of housing ?
OK, so thats more than 1 question ;-)

Andy,

 

Hi,

It is a black, plastic screw which is on the front of the housing. Follow
the drain pipe, you'll see it
My best advice is to don't care about this screw - no need to move it for a
filter change.

No problem, I guess I answered them all ;-)

there are no bleed sequences or special procedures for these types of
filters.
just remove the 4 bolts, replace the filter, and refit the top and 4 bolts,
preferably with new seals.
job done.

Many thanks to G.T. and Steve,
Job done, easy peasy lemon...etc
Just got a bit paranoid about a non-starter, now runs sweet.
I think the old filter had been on over 3 years, air filter the same !.
Would this cause any problems ?. Injectors ?
Could you recommend a fluid to run through the system ?

Once again, Thanks
Andy.

 

Hi,

Ok, so see my 7th point, have a happy motoring

I can tell you avoided the worst things ever : clogged fuel filter (poor
performance if not engine stalling & eventually pump & injectors major
fail - if engine turning with no fuel) or clogged air filter (then a Diesel
engine will take its energy from oil, which revs the engine far over the
limit and breaks it).

No, I have never tried any. I guess you right foot could do miracles (that's
the way I gave its power to my 205D, when I bought it it struggled to take
more than 110KPH (70MPH)).
