No you don`t have to drain the tank. he said he was doing some other work, and that is why the tank was empty.

I did notice he used the primer pump, then started the engine. so there might be a time laps between installing the filters, and finishing the other job, before getting back to the priming and starting the engine.

The fuel system is not under pressure from the tank to the filters. so no, you won`t get sprayed with fuel.

If your tank is full when you pull off the little pre-filter, fuel will flow out the hose from the tank. when I change the pre-filter, I loosen both clamps, pull off the the supply line to the filter. quickly shove on the new filter, pull off the old filter. fuel will fill the new filter, then pull off the old one and attach the new filter to the hose on the other end. this way there is nothing to prime, as no air is getting in.

There will always be an air bubble in the pre-filter, that is normal and won`t cause any trouble.

The spin on is like he shows in the video. Just fill it to the top and tighten the bolt. then push the primer to purge out any air until you hear a buzzing or whoosh sound of the fuel flowing.

He mentions changing the one rubber "O" ring on the bolt. I would go ahead and change both. to me doesn`t make since to do just one.

Be sure to apply some Diesel onto the new rubber filter gasket. If not and the rubber is dry, and the filter spins, the gasket could bunch up and create an air leak.

I have read where some members pour the old fuel from the old filter into the new filter. Do not do this, you are just adding contaminates to the new filter and system. Use clean fuel. ATF, Diesel purge, even engine oil in a pinch, can be used to fill the filter w/o any harm.

If after starting the engine, and it kicks, bangs, snorts and makes some nasty noises, don`t be alarmed too much, probably some residual air that was not purged. It should smooth out.
