The Dark Wob

The problem is there isn't a tap on the tank so removing the vacuum thing will mean the tank will empty.
How will I go about checking that part?

Suck on the vacuum pipe & fuel should flow? There should be a pipe that connects to the carb or intake that isn't the fuel delivery pipe, that'll be the one.

It won't take much of a vacuum to open it.

Post pictures of the pipe arrangements going from the tank to the carb, we can make sure you suck the one that will give you a gob full of petrol.
A photo of where the fuel pipe goes into the tank will clarify

Cheers guys.

I would say that red is the vacuum hose and black feeds the petrol into the carb.
Check for splits or lose connections, the zip ties aren't really the correct thing

I put them on as they were just pushed on!
I blew through the feed to the carb and the float valve works spot on. I reckon the problem lies with that vacuum bit under the tank.

I wonder if you could just fit a tap to it instead.
Have you checked petrol is flowing when you put a vacuum on the red side?

I've lost many phones to water damage whilst riding in the rain.

I've only lost one to liquid damage. Never motorcycling.

Was kipping on someone's sofa and when I woke up, knocked it off the sofa and it's curves landed straight into the pint I hadn't finished the night before. Lesson learnt and always Mastermind my drinks now.
