Do I need "fittings" when replacing fuel filter? Also, darn spark plugs!

OsoMoore · OsoMoore's Garage

I believe I am having poor fuel flow, and would like to get a new fuel filter. Do I need to order one that comes with fittings, or just the filter. Its about $20 difference in price.

Also, I can't get the darn spark plugs out! I have a spark plug socket and a 8" extension. By itself, the socket won't reach. With the extension, I can't maneuver it into position because it is too long!

The best tool in the Porsche tool kit is the spark plug wrench. It works better than any other tool I have for the plugs on my car. Without that tool, get a selection of extensions and fiddle until you have one the correct length. The extension required will vary from plug to plug. The Porsche tool works for them all. Genius!

Alas, I do not have the kit spark plug tool. I guess I'm off to find some extensions.

Any have some input on whether I need the fuel filter + fittings, or just the filter?

Filter alone should suffice.

Regarding the "fittings:" You're referring to that S-shaped metal fuel line that runs between the fuel filter and the fuel accumulator, correct? You should be able to reuse the existing one. Just unscrew the locknuts on the top and bottom ends of the fuel filter and replace.

Well this sucks - I got some extensions for my spark plug socket. After about 5 minutes I thought I fitted the socket onto the plug, and started turning it. After about 3 minutes I decided I probably wasn't actually engaged with the plug. While trying to pull the socket out, it stuck onto the not-plug. I think now I shall have to take off the little side-cowling to get this done.

Argggggg! If only I had the toolkit tool!

For a great 911 spark plug tool..find one of these. Hazet 2505-2...available online.

+1 on Porsche SST.

As a back up I use two 2" ( short ) extension and a pivoting angle adaptor, seems to be the right length

No you do not need extra fittings, just a filter but be very careful with lower fitment on the hard fuel line, it is very very soft.

I've never had a problem with a standard Craftsmen swivel socket and a 3 inch extension when I haven't had the tool kit one around.

When using a socket with the insert "gripper"......it tends to grip beyond the tension on the socket fitting leaving the socket on the plug inside the plug hole. Needle nosed pliers or NN Vice grips will allow you to grab the plug socket.

Ask me how I know....

Ok, filter is on order for Monday.

I took off the outer cowling and was able to get my socket out. Using the extension, I can fit the socket in and over the plug.
However after much rotating of the wrench, I don't think I'm getting purchase on the plug and its not moving.
I'm going to keep messing with it.

I miss the easy plugs on my old VW Golf...

LOL. I miss them on my old Scirocco and 944!

You can also wrap electrical tape tightly around extension and socket making it harder to separate.

I needed a 13/16 plug, not 5/8! I nabbed one with a magnet in it and the plug is out.
The plug has black gunk on it, smells like gas.
Its gap appears to be 0.32. Is that right? The plug is rather dirty, so the gap might be a little larger and the dirt is making it read small.

Does this mean I need to clean the electrical distributor?

OsoMoore · OsoMoore's Garage

Here's another pic where you can see the gunk on it better.
It isn't that wet - maybe carbon fouled? I have done a lot of short driving in the past due to my short commute.
I'll try cleaning the plugs and checking the dizzy. Maybe I just need more long driving.

You need new plugs and an Italian tune up! Drive it like you stole it for 30 minutes to get everything good and hot. This should blow out all the carbon and ****e built up. You may need valve guides as well in the long run, depending on oil consumption.

Forget cleaning them,..get new ones. If the distributer cap/rotor hasn't been changed in a while, install fresh components there, as well.

How many miles on your presented plugs?

As to checking your noted "fuel flow" concerns, one can look at "pressures" for spec,..then look at "volume" produced over time (flow) on the injectors' side.

Best!

... and make sure they are the proper heat range.

OsoMoore · OsoMoore's Garage

Yikes, new plugs sounds expensive.
I did clean them and put them back in for now. On the bright side, I have now acquired the tools and know-how to take them in and out in the future.
Cleaned with a tooth brush, sandpaper, and wire brush.

dshepp806 · dshepp806's Garage

WHAT? New plugs are cheap! I'd assume you'd go with the coppers out there. If anything, I thought I'd hear cost kickback comments of the distributor cap and rotor!!!!!

Nice clean job on those plugs. I'd recheck them in short order.

Best!

if you don't have the factory tool, a locking extension (got an SK one for a few bucks on ebay) or the redneck locking extension (duct tape on regular extension) work fine for the plugs.

you can reuse the fittings on your old filter if the new one doesn't come with them. the filter should come with new crush rings (definitely replace those with new).
