1990 B2200 Fuel Tank

I am installing a new tank and fuel pump in my B2200 and want to know what hoses I NEED to use? I have a weber and pacesetter headers so can I just use the filler, breather and fuel supply hoses?

Yes. The remaining hose is going to the vapor canister anyway, which isn't going to be used if you have a Weber.

Ok. That will leave 3 other hoses from fuel tank that I can just plug.
