94 sea doo do 657x not getting fuel

[Aaron787gsx]

Hey everyone I just picked up a sea doo 1994 do with the 657x engine in it. Bought it from a guy that said it was sitting for about 2 years and was garage kept and had it winterized. Compression is good engine turns over great pulled the carb off (twin carb) installed new gaskets jets were clean and it had the original fuel lines (gray lines) replaced them cleaned out the fuel selector put everything back together and for some reason I am not getting fuel to the carbs. But when I throw some fuel down in the carbs it fires up. I triple checked my work on the fuel lines. I tried blowing into the fuel line and I got a little bit of fuel to come through any idea on what I could do all fuel lines are tight would appreciate some input!!!! Thanks!

Bypass the fuel selector switch. Go from the baffle, to the filler, to the fuel pump.

Baffle? Where is that

 

[racerxxx]

It's where all the fuel lines come out of the gas tank.

I thought that was the fuel pump

Fuel pump is on the carb

Okay so on the twin carb that would be the main fuel line correct?

What I did with mine was I sucked fuel through the lines to prime them, as it take a while to prime. Use a brake bleeder so you don't have to risk fuel in your mouth. And then repeat the part where you pour fuel into the carb to finish the priming. It might fix your issue.

Just leave the return line off the rear carb then blow into the tank check valve. As soon as fuel comes out of the carb fitting put the hose back on.
No tools needed, carbs and hoses are primed, no way of getting fuel in your mouth.
