The screw on (the fuel tank side of) the fuel filter has no gasket or washers. It keeps leaking on me and I think its cross threading a bit.

I have anti seize for plugs and blue lock tite.

Can any of these be used as a thread sealant?

(sorry if this is a stupid question.)

Edit: Issue has been resolved. I acquired another new filter and torqued it to spec.

 

Don't use anti seize or lock tite.
You should have crush washers on the bolts.

Hello and thanks for the detailed reply.

Yes I am aware of these, but they are meant for the Banjo Bolt, not the fuel feed screw. (on the fuel tank/pump side of the filter. sorry if this was not clear). Thats what I call the screw, but there is surely a better/more common designation.

Notice #14 on your drawing. It is your version of the input/screw on my filter. Mine is underneath the filter.

 

Use Teflon tape to help seal the thread. Antiseize and thread lock will not stop a leak

 

Please read the rules sticky. Car information required for all tech posts.

This helps us help you with the correct diagrams and such.

Failure to comply will likely result in a thread lock.

 

ok thanks.


Sorry. Updated.

 

Awesome, thank you.

One question, why don't you replace the fuel filter? I would think you would get new crush washers etc and it would likely correct the leaky issue?

 

No, neither can be used as sealant on that type of fitting. The only answer is the correct way. If it's cross-threaded, replace it.

 

Shouldn't need anything but the crush washers and teflon tape, so you might have stripped it

 

He's having issues with fitting #14 in the above diagram. It's this type of fitting



If it's leaking, teflon isn't going to do anything for it.

 

Ok thanks.


This was a brand new filter, But I suspect it to have had some production flaws. Unless this was caused by my own clumsy mitts. (probably the latter lol).

I have now installed a third filter. It did the job.
