1940 KC / stock underseat tank. Stewart Warner fuel gauge.
I am getting inaccurate readings on my fuel gauge. I can fill the tank and show only 1/2 full. I'm thinking the sender unit needs replacing. How big a deal is to replace the sender ? One site I was looking at had me removing the tank from the truck, emptying / flushing etc.etc.
Is this job really that dangerous ?

Thanks
