simple question. What size wrench do I need? Do i need 2?

Thanks,

Mark

Yeah you do need 2, one for the filter and one for the fuel line also I think a ratchet for the filter holder.

I'm pretty sure the filter is 17mm., I used a crescent on the fuel line.

17 and 19mm. The clamp for the filter is easier to remove if you use a socket and ratchet (6 or 7mm) but I'm pretty sure you can get to it with a screwdriver too. Enjoy dumping fuel on yourself. I have every time I've changed one of these.

The nuts are tights, use as long a wrench as possible. On one end I actually used a long adjustable wrench + open end. Strictly speaking not recommended, but it didn't round the nuts...

See if you can get ahold of some flared end wrenches. It makes it a little easier and you really don't want to round off any of your fuel line fittings. Also have a catch tub handy, you'll lose about a cup or so of fuel. It's not hard at all.

Oh yea, one more point to you, don't be smoking either, could be a hot job then.

If you have to use an adjustable wrench, use it on the filter, not the gas line nut. If the adjustable ruins the hex on the filter it's not such a big deal because you're goint to throw it away.

PorscheDoc

a 19 and a 17, just position the wrenches so that they are close enough that you can squeeze them together with your hands to break them loose...you don't need really long wrenches. Have a catch pan ready, a suprising amount of fuel comes out of that damn thing

I dont know if it was necessary but when I did mine I also used a fuel line clamp. Its just a simple little clamp that you tighten down on the soft line, which doesnt damage it. I used my brother's, I think he said he got 2 of them for about $7 total off of a matco truck.

Man, what a pain this job is. I would recommend using flare nut wrenches and having safety goggles. Both times i've changed the fuel filter i've ended up with a face full of gasoline. Good luck.

With that much pressure it sounds like you didn't take the gas cap off before disconnecting the fuel lines. Nobody has mentioned doing this yet but any time you change the fuel filter always remove the gas cap first to relieve pressure from the system.

Mark-87-951

Thanks for all the responses everyone! I'll be sure to remove the gas cap. I read somewhere that you should also pull the fuel pump fuse(relay?) and run the car till it stops to relieve the pressure and clear the lines to some extent.

yes, remove the fuel pump relay it will depressurize the system and save you any troublesome gas spaying in your face, just pull it with the car running and it will die, and then get to work. You might need to use a vice grip on the old fuel pump if its difficult to get off, i also find the mahle replacement is the easiest one to work with because the bolt parts of it are bigger than generic autozone fuel filters, good luck! and close your mouth when you get it loose!!

Fuel pump fuse is #15 IIRC. Clamp for fuel line is a good idea, as are safety glasses, there will still be an amount of fuel in the filter either way, but it is an easy job. I'd leave the filter clamped in position, remove the lines and then remove filter, that way the filter is being "held" and you won't have to deal with it while dangeling from the fuel lines.
