How do I clean the fuel level sensor in my ZR-1

[TX '90 ZR1]

Here's a pic of my sending unit after rebuilding. New pumps, stainless clamps, submersible fuel hose (very important), and Carter's "Y" that he designed because the original plastic one I had split and was causing a pressure bleed down. This "Y" is the prototype. Carter has made a couple of small changes since this one to make it fit a bit better.
You will need 2 sizes of hose. 1/4 and 5/16 if I recall correctly. The submersible hose is expensive, but it is what needs to be used.
