  My approach was to double-nut the shaft with AN315-3's, followed by an 
AN960 washer and a sealing washer made from fibered gasket material inside 
the tank. On the outside, another sealing washer with a bit of Permatex #2, 
an AN960 washer, then an AN365 locknut. The inner assembly was adjusted so 
the the tank bottom is slightly lifted when the pump head is installed. The 
biggest problem was that the mounting collar had been distorted when it was 
welded and had to be rounded out so the pump flange could go in.

  I tried o-rings at first but they squeezed out when compressed. Full 
disclosure: I haven't filled the tank yet. -Bill Wade

I agree with John on the IV hydraulic reservoir configuration. I removed the 
rod that attaches the pump to the bottom of the tank and plugged this hole 
with a short bolt and sealing washers. I made a split circular clamp out of 
1/2" Delrin that clamps around the neck of the reservoir and used small 
bolts to attach the pump base to this clamp. Has worked like a champ for 6+ 
years; no leaks at all.
