The 1997 Seadoo GTX fuel line size is a topic that has been discussed on the Sea-Doo Forum, with some users seeking clarification on the correct size. Some users have suggested that the size is 1/4 for all fuel lines, which equates to a length of 20 feet. However, others have mentioned that the size could be 5/16, which is 8mm, as this was the size of the factory tempo line on their 96XP. It is important to note that using a 5/16 fuel line could potentially result in a fuel leak, so it is recommended to use the 1/4 size.

What You'll Learn
The fuel line size for a 97 Seadoo GTX is 1/4 for all
The fuel line size for a 97 Seadoo GTX is 1/4" for all lines. This is the correct size for all carbureted Sea-Doo's with a 787 or smaller engine. You will need about 20 feet of this fuel line to replace all the lines. You can purchase this fuel line from Autozone for $1.30/foot, or from NAPA for just under $1/foot.
Some people have suggested that a 5/16" fuel line is a better option, as it provides better fuel flow through the fuel system and is easier to install and remove. However, using a 5/16" fuel line on a 97 Seadoo GTX will result in a fuel leak. Therefore, it is best to use the 1/4" size.
When replacing the fuel lines, it is also a good idea to clean out the fuel selector switch and the filters inside the carbs. You will also need hose clamps to secure the fuel lines. It is recommended to use stainless steel clamps, and you may want to buy a few extra clamps to keep on hand in case any break during installation.
If you are replacing the grey fuel lines, be aware that these lines decompose over time and turn into a greenish-blue sludge that can clog your fuel system. Therefore, it is important to replace these lines with new fuel injection-rated lines to avoid any issues.

You will need 20 feet of fuel line
It is important to replace the grey fuel lines with marine-grade hose, as the inside of the grey lines can decompose and turn into sludge, which will clog the fuel tank. You can use Napa fuel line hoses, or Napa fuel injection-rated lines. The latter is more expensive, at $6.50 per foot.
You can also purchase a 20-foot Fuel Gas Line Hose kit, which comes with high-quality nylon zip ties to replace an entire fuel system. This kit is made in the USA and is designed to last longer than OEM hoses. It also allows you to see the fuel moving through the hose, making it easier to diagnose any problems.
When replacing the fuel line, it is recommended to get a few extra hose clamps and keep them handy, as they can break during the process. You will also need to relieve the pressure in the system by running it nearly empty with the valve shut off and removing the fuel cap.

The fuel filter is bone dry
If your 97 Seadoo GTX fuel filter is bone dry, there are a few potential causes and solutions to consider.
Firstly, it is important to understand the fuel line system in the 97 Seadoo GTX. The fuel system involves the fuel tank, baffle, water separator, fuel filter, carbs, pulse, and engine. The fuel filter plays a crucial role in ensuring that clean fuel reaches the engine, and a dry fuel filter could indicate a blockage or another issue upstream.
One possible reason for a dry fuel filter is a clogged fuel line. Over time, debris and contaminants can build up in the fuel lines, restricting the flow of fuel and causing the filter to dry out. To address this, carefully inspect the fuel lines for any signs of blockage or restriction. Clean or replace the fuel lines if necessary, ensuring that the correct size and type of fuel lines are used.
Another potential cause could be an issue with the fuel pump. The fuel pump is responsible for drawing fuel from the tank and supplying it to the engine. If the fuel pump is not functioning properly, it may not be delivering fuel to the filter, causing it to run dry. In this case, you may need to troubleshoot the fuel pump and potentially replace it if necessary.
Additionally, the fuel filter itself may be faulty or clogged. Even if the fuel lines appear clear, the filter may be blocked, preventing fuel from passing through. It is recommended to inspect and clean or replace the fuel filter regularly to ensure optimal performance. Refer to the maintenance guidelines provided by the manufacturer for specific instructions on fuel filter replacement intervals.
Furthermore, there could be an issue with the fuel tank or the fuel level. Ensure that the fuel tank is adequately filled and that the fuel can flow freely from the tank to the fuel lines. It is also important to check for any leaks in the fuel system, as a leak could result in a loss of fuel pressure and a dry fuel filter.
Finally, it is worth considering the overall condition of the fuel system, including the carbs and internal filters. If the carbs are clogged or the internal filters are dirty, it can impact fuel delivery and cause the fuel filter to dry out. Regular cleaning and maintenance of these components is essential to ensure efficient fuel flow.
To summarize, a bone dry fuel filter in your 97 Seadoo GTX could be due to clogged fuel lines, a faulty fuel pump, a blocked fuel filter, a low fuel level or fuel tank issue, leaks in the fuel system, or problems with the carbs and internal filters. Thoroughly inspect the entire fuel system, clean or replace necessary components, and ensure proper maintenance to optimize the performance of your watercraft.

The fuel lines need to be replaced
Firstly, it's worth noting that the fuel lines are grey, and it's this type of line that is known to decompose and cause issues. The inside of these lines can turn into a greenish-blue sludge, which will clog everything up. So, it's a good idea to replace them.
Now, onto the specifics. You will need 20 feet of 1/4" fuel line. This is the size for all the fuel lines on the 97 Seadoo GTX. You can get this from NAPA, or Autozone, and it should cost you under $1/foot. If you want to add some colour, you can get Neon fuel lines for cheaper than $1/foot from fuellines.biz.
When replacing the fuel lines, you will also need to think about the hose clamps. It's a good idea to get stainless steel clamps, and you may want to buy a few extra in case some break. You will also need to clean out the fuel selector valve and the filters inside the carbs.
Finally, it's worth noting that some people have said the correct hose to replace the grey fuel lines with is a new grey fuel hose made by the original manufacturer, Tempo. However, others have said that any fuel injection-rated line will work, and that marine-grade hose is not necessary.
