Hello,

After reading a lot of threads I have decided to replace my old,gray fuel lines on my SeaDoo. Are there particular ones I should replace or should I replace all of them? Also are there any Do"s and Dont's that I should be aware of before I do this? Thanks
 
Replace all of them.

DON'T remove all of them at once. DO, replace them one at a time. DO make sure the new hose clamps are stainless steel. DO clean the carbs, fuel select valve, and filter while doing the hoses.

Good luck :cheers:
 
Thanks Dr Honda.

When you say dont replace them all at once. Do you mean replace one at a time over a period of time or can I do this all during the same day. Meaning start with one hose, cut it out, replace it and clamp it to the fittings and then move on to the next hose?
Also whats the best way to clean a fuel filter, selector?

Your advise is really appreciated. THANKS!!
 
Yes, Dr. Honda means one at a time, all in the same day. Just giving you the advice to do one at a time so that you are certain where both ends go and you don't screw up your fuel system by forgetting what went where.
 
Fuel Selector

Remove the fuel selector by taking off the small rubber cap on the end of the dial to access a screw that will get you started on removing the fuel selector. If it's really gummed up, consider buying a new one. If it's not too bad, use a compressor to blow air through it. I didn't have a compressor so I just used a piece of new fuel line to put on the ends and blow through it. Make sure to turn the switch to clean it out. I also used a Q-tip to clean it out.
 
I put on safety goggles and whip out a can of carb cleaner for the selector valve. Hold it over a metal coffee can or plastic bucket. Hold the ports and carb cleaner nozzle away from you and other people.

Spray carb cleaner with the tube inside one of the ports. Change the valve position and repeat.

You can also blown compressed air to finish it out. Just be careful the spray-back doesn't get into your face!

I needed about 25 feet of hose for a 96 HX. If you get 30, you'll have plenty. There is some muttering about whether or not to use the marine grade fuel hose (non-fuel injected). If I owned a yacht and was spending lots of time in open sea, I'd get the expensive hose. For a 15 year old Seadoo, regular automotive fuel hose works fine for me.

Stainless steel clamps are a must. Details on the box of them I got from Napa for a lot less than other places in the photo below.


Don't forget to buy a bunch of zipties to secure the new hoses when you are done.

And take lots of pictures and make a diagram so you can hook everything back up properly later......and post your hard work on seadooforum.com!
 
I just cleaned out the small filter is the carbs on my 97 GSX and am going to do the grey lines as well. The insides of the hoses are green and nasty, they need to go!
Definately clean the small filters in the carbs! Mine were totally full of junk and are probably the reason the owner who I got the ski off of had the engine failure. Talk about motivating me to do both my skis right away!

Don't discount the marine grade fuel line soo quickly, I found that regular automotive fuel line was about $2/ft from 1/2 dozen different automotive parts stores, yet I went to one of my local seadoo/yamaha dealers and they sold 15ft of MARINE grade fuel line for only $13.99, which is $0.93/ft and the line is MUCH stiffer/stronger. They also had the same stuff with a gray (I assume paint) on the outside, if someone cares what it looks like, even that was only $18.99 for 15ft, which is still only $1.27/ft, still much cheaper then the lower quality automotive fuel line!

You can squeeze the automotive fuel line, while the marine fuel line you can not! It was cheaper and better so why would I use the automotive stuff?? Even if it was the same price or only a tiny bit more I'd still go with the marine stuff! If it was 2x the price or more, then I would probably go with the automotive stuff, but that simpily isn't the case!



To the origional poster: I replaced all the lines except the vent lines, which was 3 short runs, one from the tank which "T"-ed to a vent just under the seat and another vent out the side under the rub rail (May not be the same on all models). I didn't replace that line because it was just a vent and shouln't even even come in contact with fuel (just vapors), and would be EXTREMELY hard to get to the vent under the rub rail, so I figured I would just leave the vent lines alone. But all the other fuel lines should be replaced.
