If it's drawing from the same tank all the time, I'd check the venting or the pick-up inside the tank on the side it's not drawing from. Also check the hose from the tank to the valve to make sure it's not deteriorated on the inside and collapsing.
Is the switch itself working right?

Im sure the switch it self is working fine the reason it was replaced was it blew a fuse.how do you check the venting and pick what should I look for.

venting is fairly easy, just open the cap and run it to see if it works.
As far as the pick-up goes, you either need to remove it from the tank or blow some air through it in the opposite direction. The problem with blowing air through is you may put a bunch of junk in the tank.
A lot of the pick-ups have/had a screen on the bottom of them inside the tank. Over the years, those screens can get plugged up or they can deteriorate to the point where the screen clogs the pick-up itself.

I blew some air through the hose end when it was off the valve seemed fine .
Is there anything plugging the inlet to the valve?
Is the tank that's not being drawn from have the longer hose from the tank to the valve? If so, I guess there could be a chance that the fuel pump isn't strong enough to draw it that far.
How about the location of the valve? Is it higher or lower than the top of the tank? It should be a little lower so there's a siphon effect.
could be the pick-up fell off?

If it's none of the above, I'm out of ideas as there isn't much more to check.

oops, maybe the pump drawing air in from somewhere along that particular line. are the hose clamps tight? or maybe there's a little cut in the hose at the top of the tank?
