Your mechanic is an idiot. It has nothing to do with "Being soft" or hard. The old Tempo fuel lines don't like the alcohol in the fuel, and they decay internally. When that happens (and it will) it will send green goo into the carbs, and plug them. If it's not taken care of... in a 2-stroke... it can be the death of an engine.
FYI... the filter below should have a white screen.

I noticed when I replaced mine how easy they were to remove. The original clamps are crap. I was concerned about how loose the lines were and the posibility that air may be getting in. This may be due to deterioration and or just crappy clamps. It was a good investment to eliminate any issues.

It's not the clamps. It's the hose that was disintegrating. And yes... along with a plugged up system... air will get in.

It amazed me that all the seadoo's I looked at where people said their shop rebuilt the carbs, did this work and that work but almost all still had the tempo lines...Even a few mechanics that were selling ski's still had the tempo lines.

yip, i've seen it too, its a combination of stupidity and laziness IMO, it costs about $20-$25 to replace the lines and for an experienced mechanic, would probably take a half hour, and if they were doing carbs as well then they've already got a good start. The first time I did it it took me forever since I didn't mark the lines so then i was scrambling around the internet looking for a fuel diagram, etc, now I just do it one line at a time and its simple.

I replaced the Tempo lines in my 96 XP and it took roughly an hour going at a slow pace with a few beers and friends to distract me. In my experience fuel lines do get hard and brittle when they're old but as stated previously hard and brittle isn't the issue. I replaced all the clamps with stainless steel hose clamps for ease of removal and installation.

Mine took a bit longer, it's those STUPID PITA seadoo clamps. I HATE them with a passion, and there isn't many things I hate lol. Other than those clamps, it is a very simple job.

Once you remove a few... you get the hang of it. I use a set of side cutters, and just get an edge under the tab. a squeeze, and they pop right off.

This is one of the first things I do. I went to the auto parts store and got fuel injection fuel hose. It's a little better than regular old fuel hose. It has some sort of material inside the rubber to hold it together better or something due to the pressure of fuel injection. So I know it will hold up on carbs. I used 1/4 and the next bigger size. It was easy. Stainless steel hose clamps are the way to go. Good luck. Just do 1 at a time.

when I buy used Seadoo's and see the grey fuel lines I can already tell the condition of the motor. If I brought my ski to a shop and it left there with the grey lines, I would not be going back to that shop. The tempo lines break down from the inside and clog everything up, replace them and do an entire fuel system cleaning, from the carbs to the fuel tank. Also know that some Seadoos use both 1/4 and 5/16 hose together or alone.

Itdyfz99 is correct. 1/4 and 5/16 fuel line is what I have to use on mine. I just found 1 tempo fuel hose that I still had to do. It was some kinda vent hose to outside the hull. When I took it off there was some kinda oil in it. It wasn't the oil I used in the fuel mix either. It certainly wasn't fuel either. So, I may be wrong and probably am but, I think it broke down that bad that it actually produced some kinda oily substance. IDK! LOL.
