'Zeb' - (Not a Classic) Bloggy!

Today it was fuel filter change day. As with most of these jobs, I write up a little how too for the Volvo Forums:

Volvo 850 Ph2 Fuel Filter Replacement.


Today I replaced the fuel filter on my 1996 GLT. Well overdue in my case! My replacement was a 'Mann' filter. It is a good idea to have a new strap as it is very likely your old one will have rusted badly. They tend to give out where the captive nut sits. Remember to dis-connect the battery.

The filter is under the car next to the fuel tank on the offside, so you will need to raise the rear of the car on ramps or stands. I am very very lucky to have a friend with a 4 poster in his hanger:


That'll be him putting my car up.


Here is the old filter, you can see the 'strap' that holds it in place around the middle. Above you can make out the return pipe, this is push fitted into a 'lug' on the strap.


The pipes, fore & aft are push fit type onto the filter. To release a 17mm spanner can be used as a lever. If you hold the filter with one hand you can use the filter to lever the spanner on, pushing the pipes off. You will get an initial spurt of fuel under pressure, so have a few rags handy.


Here pushing the rear pipe off.


Here front pipe removed. Note resting it 'up' on the return pipe to stop any fuel running out.


Finally the filter removed. Note the 'plug' in the pipe to stop your tank draining! The original strap on mine was a 12mm & was very rusted. Lots of WD40 needed to get it going. It did not break mind. The replacement one, which was a Volvo OE had only a 10mm bolt.


The new filter in place, note the arrow on the filter, points forwards as in direction of flow.
The pipes push back on. I used a 19mm spanner to make sure they went 'gently' fully home.

Tighten up the strap.

Now its time to start up, having re-connected the battery. Turn ignition on and let the pump prime. Mine started on the 2nd spin, just time to get the fuel all the way I guess.
Check thoroughly for leaks. Go for a spin & check again.

Hope this helps & do feel free to add any tips or anything I may have missed.
Thanks.

Well, it was back on my mates lift today. Plan was to replace all 4 brake hose and then bleed the system with my 'Eezibleed' kit.

Turned out that, having looked at the rears I had bought 4 front hoses!!! Anyhow I cleaned up the rears and had a good look. With my untrained eye I gave them a clean bill of health.

I had been informed by the mobile mechanic that did my CV boot that the front off-side hose was split. Having eventually got that one off, it was indeed, all be it a tiny one.
T'other side was okay, but made sense to replace it. Lots of WD40 was needed to get the union to 'give'. Managed it eventually.
Full bleed & we're off again.
Phew

Aye, using WD40 it would take some shifting. Tip: in future, use a penetrating fluid rather than a moisture displacing product.
Main thing is that you got the job done though, good work.

Ahh, thanks, yer lives an' learns!

[rich.]

can you recommend a good penetrating fluid? for my shame i use wd40.

I always use Plus Gas.

Plus gas would be my choice too, I've yet to find anything to beat it at the price.

WD40 isn't entirely useless but it's best used for lubricating squeaky (moulded plastic) throttle linkages in certain tiny French cars , getting "difficult" stains out of "dry clean only" clothing or rubbing into one's baldy head as an alternative to hideously expensive moisturiser with a fancy name and a horrid smell.

^^^^ there speaketh the voice of experience

In two of the three, yes, but some say that Hambach is actually in Germany which confounds one of the above examples.

Next on the list for my 'over pampered' 'Zeb'?...... Well swmbo has complained that the tailgate has clonked her on the bonce once or twice, well maybe more over the last few months...... When I replaced the brake pipes the other weekend, it was about -5 & I lifted the gate and leaned in to get my tools.... you know where this is going..... yeh, damned tailgate hit me in the back
I've ordered some from Parts For Volvo now.............. oh you should have heard her..... "I get it hitting me on the head for months, but you ONCE & they're ordered"
