Thanks in advance David for your assistance.

No, actually I mean flat, with the cylindrical pump sitting on the  
bottom of the tank.  When I bought my van, the pump was suspended by  
what looked like a hose that was too short with intake an inch or two  
above the bottom of the tank.  In my limited knowledge of this type  
of pump, it looked as if the pump wouldn't be able to pump this "un- 
useable" water...

I will try the lead removal trick and advise the outcome.

>  look for +12 at the green wire of the sender connector

Without looking at the unit I don't have a clue what you are  
referring to.   +12??  ...Again, I'll have a look and advise

My sender is in fact the plastic "reed" type with the float;  I  
didn't know there would be any other type.

Thanks,
