All Small Six fuel leaks at fuel filter

[1981 Capri]

Have a one barrel Holley carb on a 200 . we are original owners , we think this is the original carb , it has been rebuilt a few times over the years , and has had many fuel filter changes . Now having an issue with fuel dripping from the threaded side of the fuel filter while the engine is running . No fuel dripping on the rubber hose to solid fuel line connection . Seems like every time i check the fuel filter , it is loose , so is engine vibration causing the fuel filter to come loose or maybe threads are damaged between a fitting in the carb and the screw on fuel filter ? or maybe i should think about a new carb !

Try this adapter I have one on my 1100. Stopped the fuel drip. The screw in filter was hitting the carb before it could get tight enough.

^^^ Yes, this will help keep the threads in your carburetor from getting worn out as well. I put them on carbs even if they didn't leak. You can sometimes find the same fitting at a local hardware store for less money, but it's hardly a bank breaker at Mike's. ^^^^

Thanks for the ideas and link to Mikes .
I looked at the link to the Brass fuel inlet fitting 90-63 . There is already a fitting that looks like that on the carb , the screw in fuel filter does not screw directly into the carb . The fuel leak / drip is between this fitting and the screw in fuel filter. Or should i be replacing this fitting ? Maybe the fitting i have is worn out from years of fuel filter changes ? maybe thats where the issue is ! Should i be using a thread sealant ? or would thread sealant end up inside the carb ?

Was also thinking about not having a screw in fuel filter . As this area under the air filter housing is out of sight , so fuel drip had gone unnoticed for a long time . What do you think about installing a threaded fitting with a hose bead end , so rubber / flex fuel hose between solid fuel line to hose beaded fitting on carb .
Then installed an inline fuel filter some where , maybe even before the fuel pump . maybe mount some where if there is a fuel leak at the inline fuel filter connections it's not above something hot . Would be no risk of damaging threads at the carb and very easy to change out the inline fuel filter and less risk of fire . Maybe the threads are already damaged on my old original carb . Has anyone done this on a 200cid ? until i get this resolved , looks to me like hi risk of fire !
