Fuel Filter Replacement DIY

[jblackburn]

This be pretty much the same for a 1998 V70 AWD LPT? Same location and tools?

Yep, should be exactly the same.

For anyone out there having trouble getting the "quick release" to release at all, I found that a ball joint separator puts the quick back in the process.







No problems in the 2 months since I swapped out the fiter. It's the third filter in my '97 850's life (111k miles).

I have no knowledge of the '98, but can't imagine it's much different.

Very nice write-up!

I just want to add a few tips/tricks. This can be done in 15-30 minutes.
Last time the fuel filter was changed at 60K (7 years ago), now at 120K.
At 60K, I applied anti-seize to the 12-mm bolt, it made it easier this time!

Anyway, this is the way I do it.

1. I use Bosch Fuel Filter, about $18-$20 online.
Do this job outside of the house!

2. Drive the RIGHT Front and Rear Tires on ramps. See pic.
I lay on a piece of cardboard.

3. De-pressurize the fuel as mentioned in other posts; either pull relay (while car running), or depress the Shrader valve at the fuel rail (with engine off, just remember to put the cap back on!).

4. Using a 15-mm wrench to counter-hold the square nut (this part was left out in the original thread!), loosen the 12-mm bolt. In my case I removed the bolt completely so I can lube it with grease (so it is easier to remove at the next time 60K from now).

5. Now, use the 15-mm wrench to disconnect the hose in front of filter, cap it so you don't lose fuel.
You can cap with a "finger" cut off from rubber glove + rubber band (see pic), or use the cap that comes with new filter to cap it.
Once you have the filter out of the car, it contains approx. 400-500 cc of fuel. You don't want to trash it!
So if you have a lawn mower, empty the fuel (via the front outlet) into the lawn mower gas tank.

6. The factory filter has a rubber band around it but I threw it out @ 60K miles.
- This time, I applied a few wraps of black electrical tapes so the clamp can "bite" nicely on it.
- Pay attention to direction of flow!!!
- I also apply a very very very thin smear of grease on the filter outlet (just make sure nothing gets in the hole), so it slides very nicely into the coupling. This may prevent any possible leak later.


7. Now you need to prime the fuel filter! You can either:

a. Jump the fuel relay connector but there is a much easier way.....

b. Turn the key to position II (do NOT crank the engine).
- Every time the key is turned to position II, the fuel pump is energized for about 4-5 seconds or so.
- Remove the key, then re-insert the key and turn to position II.
- Repeat this step about 8-10 times, the fuel filter should be full of fuel now.

8. Now start the engine. Check for any fuel leak.

That is all folks!

Is there no hose clamps on it? Or no need for hose clamps on it? I have always had them on bikes fuel filter...

[polskamafia mjl]

Nope, no hose clamps.

Are you guys changing your filter sooner than every 100,000?

[cn90]

Well,

I just bought a 1998 S70 GLT with 145K miles, I can see that the fuel filter is still covered in black rubberized spray from factory!
It is way overdue and I will replace it soon!

I'm averaging 60k.

CN, 145k! That filter's got to be thick with junk on the inside. Congrats on the new P80!

I changed mine well over 200K - way too long. The gas dripping out of the filter was very black.
