...Got a question...
« on: August 04, 2007, 05:51:03 PM »

   D>K  Hey Guy's,
     When you are settin up a uniflo tank (hard) do you have a particular way to hold the feed line in the tank and more importantly what do you do to keep the uniflo vent still while you soldier it ??
     I get some kind of frustrated sometimes when I do this, and each time I seem to run into another problem...
     Second question, when you use a clunk tank and you need to move something to get the up right and inverted run the same do you rotate the stopper to make changes in the engine run ???

Hi bootleg,
The solution I was shown years ago to hold the uniflow tube to the pickup tube so you can solder it in place in a hard tank is to slide a bobby pin into both tubes which locks in in place so you can get on with it. I still have bobby pins in my tank making drawer for just this purpose.

 I generally use small blocks of scrap balsa to hold the end of the uni-flow tube where I want it.  Then solder the inside the tank end in place then solder the place where it exits the tank.   Then check and recheck before you close the tank up.  You donot want ANY ends inside the tank to vibrate like a tuning fork to cause bubbles and foaming inside the tank. 
  I like the inside the tank end of the uniflow tube to be 3/8ths to 1/2 inch forward of my fuel pick-up tube end and exactly level with it vertically.  I always solder the uniflow tube to the pick-up tube, and the pickup tube to the tank wall.  Both tubes are cut at a 45 degree angle so there is no way the tubes can slip during soldering and block the end.

I generally silver braze the internal lines to the inside of the tank. You can silver braze with a propane torch. The silver braze melts hundreds of degrees higher than solder so there is no chance of anything coming loose.
