Fuel line replacement

[OutlawBiz]

Alright, I've read a LOT about the need to replace the "gray" fuel lines to prevent the gumming up etc.

I'm not gonna lie...I know NOTHING about PWC's but am trying to learn. I looked under the seat of my (new to me) '99 GS to see if it still had the gray lines. While looking around, I found what I assume are the fuel lines. There is a cluster of 4 lines coming off the top of the fuel cell in a sort of manifold cluster. Problem is...they are what I would consider to be TAN in color not "gray"!?

Oil lines appear to be black. So...are my "tan" hoses actually the stock "gray" that everyone says need replaced? Engine compartment is EXTREMELY clean and grease/oil free so there is no doubt they are tan not gray in color.

If these tan lines do need ot be replaced...is it a difficult process? Looks to be a bit cramped in a few places to access unless more than the seat can be removed to gain access. Then is it just a matter of buying bulk automotive hose and pulling one at a time and replacing?

If they arent black, Id chuck em. Its not an expensive update.

Yes, there are some that are a little cramped. Do one at a TIME. Some are vent lines, some are fuel lines. Dont get them mixed up.

Search around and see what you can find, theres two different sized. I think one is about 20' and the other you need is 5'. Its been covered lots but I forget what the sizes were. Sorry. Plus a pile of stainless steel worm gear clamps. If your fuel selector is hard to turn, now is the time to fire some cleaner through it. Dont forget to check the carbs while your there to see if they may be in need of a rebuild kit. They each also have a little filter in them that can get clogged. You can clean them out and re use them.

Hi,

You can tell for sure if the fuel lines have the word "Tempo" printed on them. They are a two piece design with glue holding the inner and outer layer together. What happens the alcohol in the modern fuels dissolve the glue and it turns into a green goo.

If you need to change the fuel lines, on your ski I think you need about 20' of 1/4" automotive fuel line and about 5' of 5/16". You only need to change the hoses that are required for fuel delivery, you don't need to change the vent lines.

I use 1/4" cable ties, they are easier to install and remove, and I think they grip better. If you use the cable ties get good quality ties, I use "Panduit" brand from Graybar Electric, get the black ones.

Here's and excellent thread on the subject.

Hmm. Some reason I thought it was 5/16 and 3/8 that was needed. maybe not..
