Hobby store....fuel line for RC Cars.
I just did this and, to make your life MUCH easier, buy 5/16" fuel line for the lines that are labeled 8mm, and 1/4" line for the 6mm lines. A lot of guys on here say to put 1/4 on both, but that makes the fuel line the bottle neck in the system, and also makes it a complete PITA to put them on the 8mm fittings (and possibly breaking the plastic ones).
If your'e going to replace the little hoses, I would think you might be able to get by using tiny wire ties to hold them on. Someone else should give a second opinion on that.

It is really differant on skis from what I have seen, but on boats you always replace them with marine hose, when I replace mine on my 2000 gtx I am replacing them with marine fuel hose.

I think I read somewhere that 20-25 feet is enough. I think I bought somewhere between that amount and replaced all but one vent line. Sounds like a lot but it gets used up quickly.

I do not understand why jetski's do not need to meet uscg approval but in boats you must use usgc aprroved hose, thats why I brought that up, marine hose will way out last automotive hose. I am going to replace all my hoses with uscg approved hoses.

To each his own. If that is what you want to do. No big deal. I like the automotive cause it is cheap and readily available. I don't know why jet ski's don't to meet uscg approval? Some things on mine due but, that may just be a state thing. I probably need to replace the vent hoses. I did not change the hose between the carbs. I can't get to it.

That one was tough, but I took my time and got it without even having to take the arrester plate off.

JinSC....did you replace the "check valve" inside those xcelleroator lines?

I did my '94 SPX with auto lines 1.45$ a Foot. 1/4 fit perfect, Got 20 feet and used 18ish. Got all stainless clamps but cost me $37.00 needed 19 of them.(Used magnet to test stainless.) For the oil lines I went to the lawn mower store and got some thick gas/oil/ethanol proof lines they use on high end weedwackers/ or even racing go-peds, only need maybe a foot but I got 3' for about 5$. I also replaced all the clear hoses with new ones just to make sure water was flowing right. I know they get yellowish brown after a few years but all the hose were about 5$. Spend the money and not have to worry later down the road.
Has anyone put a inline filter into the fuel feed line just before the carb? That way it could clog up instead of the one inside of your carberator, and would be a much quicker fix. Does anyone know what the micron rating is on the internal filter in the carb? Something like this I think would work great, I just don't want it to bottleneck the fuel feed system and cause issues.

Actually, I did not replace the accelerator lines. It was the short individual return lines coming from each carb that "T" together that I mistakenly spoke of. What I did with the accelerator lines was, I blew through them with compressed air and checked the functionality of the check valve. It all seemed to be clean and function properly so, I let them be. These tiny lines where grey, but they did not look like they had the clear inner liner like the other grey fuel lines did. Do I need to replace these?
