Js 440 bn44 wont pull fuel.

[DirtTOwater96]

Hey guys i got a 1980 js 440 that had a starter that wouldent engage amd needed carb work. I got the starter figured out and carb has been gone through.
The ski will start off primer fuel but will not stay running after primer fuel burns off.

The kid i got the ski off of said he just replaced all the fuel lines wich is true there are new, that makes me think maybe there routed wrong??
Can i by pass fuel selector by running the fuel pickup line strait the carb to ruel out some stuff?
and the carb im talking about is a bn44mm im pretty sure, it has a high speed ajuster, a low speed ajuster,and a pilot jet ajuster i think?? And the ajuster on throttle linkage for idle, it has 4 bolts for flame arrestor on top of carb. From what i read this is a 44mm bn correct ??

So if some one can take tge time to tell me or show me how fuel lines should be routed ? and what the problem could be i would realy appreciate it ?

Ski has: L S exhaust manifold,ocean pro intake manifold,west cost pipe cone and exit pipe if that helps.
Thanks for any ones time who takes tge time to help me out.

Check to see if the pickup in the tank didn’t come loose and fall down into the tank. Had that happen on a Laser Jet a couple weeks ago.
