Changed fuel lines in 97 gsx, what now?

[trunner143]

I changed out the grey fuel lines in my 97 gsx. Cleaned the carb filters and the fuel selector valve.. all full of the green goo.

My question now is, how do I get the air out of the lines, and get fuel flowing through them again?

Pull the choke, and crank the engine. It will start in a few cranking cycles. (5 to 7 seconds each)

Not a big deal.

I just did this today on my 95 XP... Make sure the gas selector isn't in off position! lol I got worried the first couple minutes, but once I turned the fuel on, I just turned the engine over (start button). Once I saw gas was in filter, I used my primer (changed that from choke on my ski long time ago) to pump some gas to carbs and it fired right up...

Changing the choke to a primer helps a lot getting these things cranked...

Good Luck!

On mine I pulled the return pipe at the carb so I could see when it started spurting fuel.

Don't spin that starter too much and let it cool between attempts - they are not designed for lots of churning of the motor without being allowed to cool between tries.

I tried choking it and starting it.. it cranked up after a few tries but the engine just revved up like crazy, really high rpms on idle. still alot of air in the line, and it doesn't seem to be going anywhere. a little bit of gas is getting out of the fuel filter/water separator which I filled with gas, but it doesn't look like any more is going in.

anything else it could be? or should I just keep trying to start it?

check the o-ring on the filter

sorry, your question is a little confusing (at least to me). Why do you think there is air in the fuel line? In this post you say the engine is running after changing the lines, but in the next post you seem to indicate you can't get it running. "should I just keep trying to start it?" I'm not clear on if it is now starting or not?

My experience after cleaning/dumping the fuel from the filter or replacing a line has been like Doc says, it takes a few seconds of cranking the engine to get fuel back in the lines and then you should be ok. I have the same ski as you and changed some fuel lines and cleaned the filter a couple weeks ago. I cranked it about 10 seconds and it didn't start so I started to wonder too. I unscrewed the filter bowl and it was full again so I just cranked a few more seconds and it started up fine.

If your filter bowl is not filling up again, my GUESSes would be, you are sucking air at the filter (bad o-ring or cross threaded the bowl), the filter inside the fuel tank may be plugged (but you should have had that problem before you changed the lines), you don't have gas in the fuel tank, or you might have connected fuel lines incorrectly when you replaced them (did you do them one at a time to make sure they didn't get crossed?). Anything beyond that is above my pay grade - sorry.

just another thought, if you are thinking you have air in your fuel lines because you see air bubbles in the clear tubes on the front of the engine, those are oil lines (i believe from the injector pump to the carbs). Air bubbles in there are bad and you shouldn't run the engine until you read the procedure for clearing those bubbles.

If I am reading your post correctly, It cranked and is now revving out of control.
If you pulled the carbs to clean the internal filters, chances are good that you carb base gaskets are leaking or misaligned causing an air leak.
This will make you engine rev out of control and the only way to shut it off is pull the choke. I would pull the carbs and check...cheaper than a new engine.
Fix that water seperator leak with a new O ring. Install it using a little vasoline to insure a good seal.
