    They are fine, the hoses dont plug into anything and the big black knobblys are the same. They are all good.

    As for pump, grav feeding should be fine.

    even though it goes down to the on/off fuel switch then back up to the carbs ? I think I'd prefer a pump but the fuel outlet is above the inlet in the carbs ... slightly. And my finances will not stretch to add a pump for now.

    Red boxes are breathers.
    Blue Box is fuel line.

    You can grav feed the fuel through the taps, i did it for two days without a hitch before i put my pump back in, if are really worried about gravitational pull, you could go about getting a metallic T Pipe or Y pipe and just merging the two lines into one and keep it short enough so "gravity" works, but im pretty darn sure the vacuum in the carbs will do all the pulling, the pump just gets it in there for shits and giggles.
