I cant see the picture due to my connection. But if its NPT then yes put teflon tape on it. If its AN, use a rubber oring to seal it.

The brass fitting on your fpr return line does not need any tape or an o-ring. Do not over tighten this fitting though or it can leak. Those type of fittings need to be just a little over snug.


As for those blue anodized fittings they need to have 1 o-ring between them and the fpr unit.

That is also an Aeromotive AFPR.

Ok thank you so much for your help! i got the o-ring on the an fittings too.

Yes it is, i borrow a pic from a member.

Mine is Fuel lab AFPR and i don't have any pics of it. I don't have a camera to snap a pic right now but the fitting are exactly the same tho. I got the Fuel Lab AFPR from extreme psi a couple of days ago.

Ok ill put taflon tape on NPT's too. Thanks bro.

Oh, one more thing! Fuel Lab fuel gauge is not liquid fill, why is that? I don't know if they all come like that
