I pulled the tank and completely re-plumbed my fuel system, including new little red seals on the bungs at the bottom of the tank. Cleaned all the hardware thoroughly before re-assembly.
Now, the garage smells like a refinery. Unfortunately, the bungs are leaking like crazy. Not quite dripping, but they are wet enough to be the obvious source of my leak. Any tips on getting them sealed up properly? Is there only supposed to be one little red seal on each bung, or two? |

I would use a copper washer to seal it. The seal sould be on the tank, between the tank threads and the nipple. The cap nut holds it on. I'm not sure what the "red seal" is. If it is a stock seal put it in the same place. There should be no seal between the cap nut and the nipple.

I'm not sure what the "red seal" is. If it is a stock seal put it in the same place. There should be no seal between the cap nut and the nipple. That is the manner in which I installed them, other than the copper washers. I bought SS lines from Rotary, along with a new sock and the seals. The seals look exactly like the old ones I removed, and I installed them between the nipple and the tank. Any other ideas? |
