Gray fuel lines help

[Vandyck]

Hello all.

I know there are a lot of topics about it, but only saying you should change the gray fuel lines...

But i have few questions. first, When we have to change the fuel lines, which one should be changed? all the system, since the tank and till the carburettor?

The most principal question. When can I know that they need to be changed?

See the pictures attached, i am not sure which ones are the fuel lines.
The Ski is a 2005 GTI 717, carburettor with only 14 hours.

Thank you all. I am sorry about my english, i am from Brazil

There are no fuel lines in the pictures that you posted. If you have grey fuel lines they need to be replaced, I'm not sure if the 2005 GTI even had grey fuel lines. You can leave the vent lines grey, all the others should be changed.

Here's a thread on the subject.

With only 14 hrs that tells me that it was stored more then it has been used. Sitting can be, and usually is worse then beating the %#$& out of it. The age alone justifies replacing all the grey fuel lines if present, minus the vent lines like Lou said.

i think he meant the carbs have 14 hours on them, not the ski,

if he meant 14 hours on the ski, I agree totally, its worse to let them sit than to run them

 

[LittleAl]

Ahhhh, you may by right.

either way, he's taking pic's of the wrong stuff !

I think I would change them all. When I pulled the vent lines on mine they were full of varnished gas. It looked like oil. I didn't want to chance that getting back to the tank or the carbs. Just my two cents.

open the engine bay.
find the fuel tank.
look for the lines coming from the fuel tank and going to the engine.
if grey, replace one at a time.
if black, you're good to go.

That's my SOP and all I'm sayin' 'bout that. :cheers:

I agree. Change them all. There are actually two vent lines. One is to let air in and one is to let pressure out. The vent to let pressure out often weeps gas if the tank is kept full. That means these lines will and do deteriorate as well and usually clog up the pressure relief valve causing it not to function properly. Also, with the positions these PWCs can end up in if you are a wake jumper and/or like spinning around and stuff gas will end up in both vent lines. You need to check the both of the vent valves for proper functioning anyways, so might as well replace them while your at them.

I havent started replacing mine but will so in the very near future. If my memory is correct dont some of the lines go up under the foam on each side. Seems like I remember that it didnt appear Iw ould be able to pull them out.

Is this correct or am I thinking incorrectly. If I am correct do you just reroute along side the foam ?

thanks

Unless someone has re-routed the fuel lines, the are all in the open, none are under any foam.

Well hopefully you are correct as I dont want to cut lines off and leave them partially in.

One a somewhat similar note what type of fuel pumps do these things use. I cant remember seeing anything of the sort but I also havent had it totally apart yet.

Are they mechanical or electric ?

 

[JJinSC]

The fuel pump on these are bladders in the carbs run by vacuum from the engine via a pulse line.

Hi.

So, all the lines are black (as the cars).

The ski has only 14 hours, Since 2006 (with 11,5 hours) to 2011 the last owner used only for 2,5 hours. But the ski is very good, there isn't any problem, i did the question about the fuel lines only to check.

The last owner he used to keep the ski in a Marina, it's one of the best marina and Seadoo seller of Brazil, its very expensive, they usually used to turn on the ski and do all the maintenance...

I see said the blind man... Guessing thats what the spinning plate deal is all about... creates a pulse... Maybe... kinda... sorta
