I have some Zx9r carbs - Which pipes are the fuel lines? Do i need a return to the fuel tank? And which pipes do i block up?

I think they are the same as blade carbs.

The inlets are the ones between cyl 1+2 & 3+4 at the bottom of the carb. There is no return to tank and the pipes coming out from the top of the carbs are breathers so put a breather filter on them.

It depends which carbs you have IIRC, if the throttle linkage is in the middle there is an inlet between carbs 1 & 2, and 3 & 4, if the linkage is on the end, its a single inlet in the middle.

There are two pipes higher up the carbs, between 1&2 and 3&4 these are vents to atmosphere or the airbox.

I have the carbs with the throttle linkage on the side not the middle.

my throttle linkage is in the middle, and i plugged my fuel into the one in the middle too, it worked, but fuel did seem to come out of everywhere, and was a manky colour. will have to have another look. don't think i've got any other inlets

just had a look, between 1&2 and 3&4, i've just got straight connecting pipes (not Ts) and only a T in the middle

If its in the middle there model E carbs 10mm pipe
b / c have two fuel pipes no return to tank
