It´s a very useful trick to use a syringe to force the fuel through the fuel filter and well into the fuel pump when starting for a fist time after such a disassemble, also works perfectly when adding the brake fluid it just forces all the air out and don't create any vacuum that sucks the air back in ;)
You can also see that I´v replaced the fuse-box (to be under the seat) ..don't wanna remove the fuel tank all the time I need to change a fuse ;)
