300e Fuel Pump Relay Fuse

1990 300E

I know the location of fuel pump relay. On top of the relay there is a 10A fuse flused to the body of the relay. How do I remove the fuse to check if it is burnt or not?

THe car won't start. I added few ounces of gas on to carbureter or air intake. The car started and ran more 45 minutes till I turn-off the engine. In this way, I believe the ignition system is working. I thought that it may that residual pressure is not maintained once the care is turned off. Therefore, I replaced fuel accumulator, but the problem still exists. I am ruling fuel filter, because the car once started runs without any hic-cups.

Your help will be greatly appreciated
