I have persistent leak at this little tube and it seems to seep gas from either the center of the nut or perhaps from the threads of the nut and fuel tank, I have replaced copper washer and still leaks. Should there be two washers woudl that stop the leak one on either side of the washer that seems welded on to this little tube or just the one washer? the copper washer goes between the tube and bottom of the tank ? what about the filter is there an addiitonal washer?
Should I replace the tube and the nut and new washers again Is there anything like a pipe dope that I could put on the threads that would help? Cannot seem to stop the extremely slow leak. It did not leak for months and then started again. Impossible to tighten the nut further than it is already |

Good timing. I'm about to put my tank back together after cleaning and have been wondering the same thing (sealant or not).
But first, I believe the copper washer may be part of your problem. There are two tube fittings and the one pictured appears to be the outlet supply to the engine. If that's correct then it fits up into the strainer screen that includes an aluminum crush ring. Then, according to the link below and other sources, there is supposed to be a red fiber washer. https://914rubber.com/fuel-strainer-screen-for-porsche-914 If not already you might want to extract the screen (which, if like mine is probably partly blocked) and get a new one with a fresh crush washer. I ordered one of these and it arrives Monday so I can update on fit. Ron |

Ron Your image doesn’t show an aluminum crush washer just a screen and the red washer- however if I am not mistaken those are copper washers that have red dye on them I could be wrong |
