I added the belly tank to the Valk.
Only problem is that the petcock leaks... but not all the time... it ONLY leaks in the "On" position. There's no leak in the "off" or "Res" position.
Can someone tell me what I did wrong??? Did I put the petcock back together wrong??
Any help on where to look would be appreciated.

Hmmmmmm.... It seems no one knows...  How about this... does anyone know where I can get a replacement petcock that does not use the vacume and has the same connections for the turn knob?? I'll just change the whole thing if needed. |

Google "pingel petcock"- don't believe the "turn knob" is an option, also a search of the old tech archives will give model #'s and pros/cons, as well you can getteh repair kit and reseal your present one

Gut the petcock and put a piece of gasket material between the two piece and button it back up. I've been running my I/S without the vac side since nov last year. I just turn the fuel off when I turn the key off. Good habit to get into anyway.

If you decide to change to Pingle: the 1311 CH and the 6311 CH are without vacuum. They have different handle positions. The OE knob doesn´t work, so yyou have to remove the knob, and reach under the tank. I use a Pingle, and will not go back to OE.

OK.... NOW I'm mad....  I went on the first test ride... and the factory connections on the belly tank start leaking!!!!!  So, now I'm draining the belly tank, which has no easy way of draining, so I can take the pump loose and goop up the threads better and stop THAT leak. Then I can go back to trying to fix the petcock leak. I'm going buy a lottery ticket... my luck has GOT to change at some point... and when it does, it's got to be BIG!!! |

Are you saying the belly tank is leaking from the bolts that hold the pump on?

It's leaking from the line going into to pump. One of the connections between the hole in the tank and the pump has a leak. The gas wicks around too fast for me to figure out which one.
I just took the whole thing apart, cleaned up the pieces really well, and put it back together with some thread sealant. Hopefully this fixes the problem. I couldn't see any obvious places for it to leak while taking it apart. (No cracks or broken pieces.)
So... thread sealant on all belly tank connections... gasket material on the petcock... and all back together now...
Now I get to put gas in it again and go step by step through it looking for leaks. If there's no leaks, run it a few miles down the road to get some Sea Foam into the carbs (it's been sitting a while) and let it sit. Then double check for leaks again and run it some more.
Hopefully... HOPEFULLY... I've got everything cleared up on it so I can go riding again!!!!

A couple of "heads ups" that you may not be aware of :
- not all thread sealants will tolerate gasoline,
- NPT threads are tapered, collars and couplings sometimes crack as the mating fitting is threaded in and when it is threaded back out the cracks will close up and are hard to spot, they will usually just show as a line perpendicular to the threads.

 I did make sure the sealant would hold up to gas. I check the threads as best I could. Didn't see any lines/cracks. I put it all back together and it all looked good. Put gas in and it's holding. I'll go take a ride on it when I can and see if it holds. I'll keep my fingers crossed.  |

I had the same problem. Took the tank off several times trying to figure it out. Used the blue locktite on the double headed fitting and screwed it into the bung as far as i could. Thought I was going to have to take the tank back off and take it back to the welding shop that installed the bung; however, i ended up parking the valk for over a month while i away with no gas in the main tank. 3 weeks ago came back, filled it up and rode it to my mom's. The next morning I walked out and couldn't smell gas so I checked. Nothing was leaking. The only thing I could think of was the locktite finally cured and sealed while the tank was empty and i was gone. |
