Sea-Doo Fuel Line Replacement and Function Description

[@fergusonmichael2097]

I got lost replacing my pulse lines after a full resto on my GSXL and this got me back on track, far more info than the shop manual gave me for routing and identifying my mix-up. Thanks

[@paulhaines5755]

Thanks! I try to offer as much detail as I can. Glad it helped you.

Awesome video bro! Got the exact same jet ski used and kept smelling gas so I jump on KZbin and ran into your video. I took everything apart to see and learn how the fuel lines ran and found the problem! Previous owners ran the tubing directly to the carburetor by passing the filter and found none of the tubbing nipples had zip ties or nothing clamping to the carburetor! That’s when I noticed moister on the bottom of the hull….gas must of been slowing leaking out the tubing not being clamp to the carburetor! I’m gonna just do what you did and replace all the lines…. Thank you!

[@paulhaines5755]

Glad it helped you! I'm a detail kinda person so I think maybe that helps when I explain things to others. Or... I put them to sleep ha, ha...

@@paulhaines5755 bro! I just got my new fuel lines today and I was wondering how the hell do I get to that main line (gas tank to ?? oil I think line) that’s under the carburetor? I’m assuming I might have to zip tie that one? There’s no way to clamp those down with out taking part half the engine apart? Lol! That’s the only one that has me spooked!

[@paulhaines5755]

Sounds like an oil line to me. If it goes to the small oil tank or the oil pump on the front of the engine it is an oil line. I only replaced fuel lines. All are easy to access. The oil system is seperate from the fuel system. I doubt you need to worry about oil lines unless you have an oil leak somewhere.

[@RAMIROANGUIANO]

@@paulhaines5755 yeah your right! My bad I assumed since I seen yours with that blue tubing 2! Thanks!

[@davidrivas2046]

Paul ! Great video and thorough info on the fuel system. I have a leaking line from fuel selector . Gonna go tackle it.

[@paulhaines5755]

You bet! Glad to help.

[@Crappie_Hunter_Seeker]

Great job ! Thank you.

[@benwilson593]

Amazing video jet ski been out of use for 18 month and u just sorted it in 10 mins !!!

[@paulhaines5755]

Glad I could help!

[@denniscox7233]

Paul I did the same. How do I prime the fuel lines, can’t get any fuel.

[@paulhaines5755]

Mine started fine so I can't say for sure. However, my Yamaha wouldn't get fuel after I rebuilt it and replaced the fuel lines. As I recall, I unhooked the fuel delivery line the next connection upstream of the actual carb connection. I put a tiny funnel in the line and poured fuel in it and let it sit for a bit. Fired right up.

[@FradyKatt]

Make sure to check INSIDE the GAS Tank. the pick up lines can Dry rot and fall off into tank, this was my problem with my SP

[@paulhaines5755]

Good info - I'll keep an eye out in there as part of maintenance.

[@scottdufour1461]

How would I re-pressurize tank after total rebuild ?

[@paulhaines5755]

Hmmm - mine just fired up no issues so not sure on this machine.. I'd suggest pulling the line going to the tank to the pulse pump and gravity feeding the pulse pump some gas. This might help it to prime itself. Maybe use a baster or something to force feed it but don't put the baster back in your wife's kitchen drawer ha ha! I did that process on a yamaha once and it worked. You'll need a tiny funnel or a baster.

[@JasonRosen_]

Thank you. This was helpful.

[@paulhaines5755]

You are very welcome.

[@gabbyjay6822]

I just discovered your channel Paul and really appreciate your videos I have a 96 speedster different machine but same motor and your videos on the cooling and fuel system has helped me immensely thank you so much my friend god bless....liked and subscribed

[@paulhaines5755]

You bet! I'm glad I could help you.

Hey great video, I know this has been posted quite a while ago but was hoping you could help me with something. My father passed me down his 1997 GTS that had a fuel leak in one of the lines and I'm currently replacing all of those. There is one hose that was also disconnected that I cannot identify where it goes. It is attached underneath the back of the rear seat and has a 90 degree elbow and a rubber grommet to go out the back. I have the grommet replaced and will get the elbow to go in it but have no idea where the front side of it is supposed to attach to. Its almost brown in color and cannot see any fuel in it but not sure if that's because it's been disconnected so long. If you could let me know I'd greatly appreciate it and it would save me quite the headache.

[@paulhaines5755]

Kinda sounds like that is the "pee valve"/"tell-tale" for the water cooling system. Watch one of my other vids about improving your tell-tale stream on this same machine and it might help you identify the hose. It's possible the line is supposed to be teed in with a line that goes to the rear most part of the exhaust system.

[@cmcd082]

@@paulhaines5755 I had asked on the sea doo forums as well and the consensus seems to be the battery vent tubing, I got it with no battery installed so that would make sense.

[@paulhaines5755]

nice! yea - that makes sense...

[@cmcd082]

@@paulhaines5755 Thank you for the quick response though, this is my first watercraft so trying to learn as much as I can about them

[@paulhaines5755]

Lots of fun. Keep you eye on anything rubber related to exhaust and make sure clamps are tight and fittings are square to one another. A major leak can fill hull with water. Also, new wear ring makes a world of difference in the HP department.

[@bityw1234]

I have an slow oil leak from the hose going under the motor, having a hard time getting to it

[@paulhaines5755]

Hmmm - not sure what to say. If it's an oil line, I have not worked on those on this machine.

[@ralphzavala8757]

I can't seem to make the fuel go through the system after doing all that

[@paulhaines5755]

If the pulse pump is not "primed" aka dry, you can have difficulties getting fuel to flow. Find a fuel line upstream from the pulse pump (pulse pump supply line) and pull the end off ( the end not attached to the pump) and pour fuel into the line until it gets into the pulse pump. Try to start it and hopefully it will work for you. This has worked for me in the past after doing a full rebuild on an engine = dry fuel system.

[@ralphzavala8757]

@@paulhaines5755 thanks Paul I'll try that when I get a chance and let you know

[@paulhaines5755]

Watch this youtube vid "Priming an LX-277 Lawn Tractor Fuel Line" This person does a good job explaining the priming process on a pulse pump system.

[@victorochoa679]

Same process be done for oil lines

[@paulhaines5755]

I suppose so. I have not replaced the oil lines on this machine. I believe most oil system hoses have check valve(s) on them. I know yamaha does but not sure about SeaDoo. It would be wise to replace those check valves with new "good" quality or oem check valve(s) when you do the lines. Also, consider a new oil tank grommet if there is one on this machine. These like to leak when they get old. Look online for a schematic to find out. Most importantly, many oil injection pumps need to be bled after you work on them. I have not done a SeaDoo but I most certainly would make sure you bleed the pump and prime the lines before you run it. Lines should be air free as that can cause the pump to not move the oil like it needs to.

[@ricovelez4316]

Did your seadoo bogg before this fuel Line swapp

[@paulhaines5755]

No -it ran fine. I just did it as preventative maintenance since it is an old dog.

[@FradyKatt]

the blue gooo is from Ethanol.

[@paulhaines5755]

Bad stuff!

[@davidj.platter3555]

oem fuel lines will dry out and break

[@paulhaines5755]

Thanks for the input! Paul
