sending unit inside tank bad

1979 Chevy luv 1.8 everytime I turn on the lights running light fuse blows, everything else work, lights, turn sin.

It sounds like the carburator needs to be rebuilt. If you have to hold it to the floor to get it to start that means it's flooded. So, the carburator is leaking gas into the engine when it's not running. Are getting poor gas mileage too?

The fuel has to be drawn to the pump with vacuum made by the fuel pump. Disconnect the feed line to the pump and install a vacuum gauge, crank the engine over and see if it has 8-10 in of vacuum. If not the pump is not working properly. If it does, check the fuel lings that go to the tank. If there is a crack, it will not pull the gas to the pump(like a straw with a hole in it). If that all looks fine, you may have an obstruction in the tank. Back flush the fuel line with air and listen to see if you can hear air of bubbles in the tank NOTE if there is a lot of fuel in the tank,some gas may splash out. If you hear air, Blow air from the tank forward to the disconnected pump feed line. If there is fuel in the tank it should flow out. If not you may need to R&R the tank to find a problem

Below is the firing order diagram for your chevy. I am assuming it is a V-8. If it is not, let me know.
The #1 spark plug wire starts in the 5 o'clock position in the diagram.
Good luck, hope this fixes it.
Regards,

it sounds like the fuel line is clogged. or you are out of gas

Its located behind the linkage on carb. left side.it will have a little spring behind it.

Maybe it's just me, but do you think that "Chevrolet 1983 K1500" is the correct place for this question?it sounds to me that your paper level sensing switch is jammed or broken. Look for a micro switch that has an arm that lays on top of the paper stack. It may be bent or broken.
