Rust on Fuel Line...

[McLin]

Hi,

I wantet change my Fuel Filter, but the screw from Line to Filter is full of Rust, what kiond of tipps did you have, to get the screw off, without to have a round screw?

[jeffcoslacker]

Let soak with WD-40, then use a line wrench or a vice grip...usually they are not as stuck as they look like they should be.

You'll get a lot of spray when it comes loose if you don't depressurize the line first...be ready for it...

[McLin]

ohoh, that is not good answer... I go every hour down to the car, and spry wd40 on the screw and line... Hope thats help.
How long is the line from the Filter to???

WD 40 may not free up a heavily rusted connection, , use PB Blaster or some dedicated rust busting product.

[McLin]

mhmm, on WD40 can stand rust... But the name you say is not in stores here in Germany, but Caramba...

[McLin]

Is this turn correct?

Turn

Just press the hand together?

[DnaProRacing]

blaster is a good product for that, as well as deep creep. but i think if you add the right amount of pressure while using wd40 you should be fine...

Yes and make sure you use a 5/8 6 point line wrench to avoid rounding the nut on the fuel line.

There are special pairs of Vice grips that grip over rusted and rounded off fasteners if the 5/8 line wrench does not work.They do work and are not cheap,about $25.00 a pair.I have seen cases the old fuel fliter has to be cut first with a recipicating saw

[McLin]

The screw is now round, I bought the right ratchet, but the screw gives up... Now I think I must cut the line, and buy a new screw, right?

[maxwedge]

Try vice grips.

[McLin]

And fix the screw? I cant never useing the ratchet...

Either use vise grips or replace the whole line. No point in trying to reflare a rusty line.
