I'm dealing with a leak where the NEW brass fitting threads onto the outlet of the sediment bowl. I thought the threads were 1/4" pipe. The fittings I can find don't get tight on the tapered threads before bottoming out. Otherwise my bulb looks like new. Thread sealant?
If memory serves me well, I think this is a straight pipe thread and not the normal tapered pipe thread.
Do you have the felt packing in place inside the nut?
I have had good luck with the felt packing, but the vendors also sell a neoprene packing.
Even with the felt packing I put a light layer of Loktite 567 on the sediment bowl threads. No leaks.
Put some of this http://www.aircraftspruce.com/catalog/cspages/ezturnlube.php?clickkey=218206 on the part that goes into the sediment bowl. It lubricates the threads and helps to seal.
I guess I have the wrong fitting. Mine is a female 1/4" pipe (tapered) to 5/16 compression. No packing. Will I be able to find the right , non-tapered pipe fitting at a hardware store?
Do I need # 2910 and 2913 (Langs)?
I used the method shown in the lower photo.. neoprene inside the pack nut. I used a thin coat of EZ-TURN on the threads and there is no leak anywhere. good stuff!
Tommy: Yes, I made my own version of the 2913N neoprene gaskets from a piece of fuel hose in my stash.
Tommy, neither the brass side piece on the sediment bulb or the brass elbow on the carburetor are machined to allow a compression fitting to seal. The acorn will compress onto the pipe, but it will not conform to the cast surfaces on the T fittings.
You need to use either of the suggested gaskets. I do as Roger K does.
Hope this helps.

Permetex Fuel Resistant sealant works amazingly well. I have used it on several fittings that wouldn't seal. https://www.permatex.com/products/gasketing/gasket-sealants/permatex-permashield -fuel-resistant-gasket-dressing-flange-sealant/
