[FC] fuel pump

[Wild8bill at aol.com]

I replaced my failing fuel pump with an electric one about 6 months ago,  
problem solved. New problem started: the pump failed on me a few weeks ago, and  
I replaced it with a lower pressure pump, because I thought it failed so 
quickly  due to it being a higher pressure pump than the engine needed. The new 
pump got  me home just fine, but after sitting for a few weeks, the rampy idles 
fine once  started, but after driving a few blocks, sputters and dies.

My question is: what is the proper fuel pump pressure for a corvair 110  
engine? The pumps that I used are universal fit electronic pumps, the higher  
pressure one is 5-8psi and the lower one is 2-4psi. I can't find a reference to  
this in any of my books or parts' supplier catalogs.
 
Other question: I purchased a float from a big vendor to replace one that  
had pin holes in it, the one that came wasn't in much better shape. Are there  
new ones available, or is there a fix, such as using gas tank sealer, to rehab  
the old ones? I'm aware of the soldering method, but I'm not sure what type 
of  flux or solder to use, or how much heat.
