Fuel System Diagnostics Question
Working on a 98 SLTX. I have figured out (Thank you cheap clear fuel hose) that the fuel system is not air tight and I have air getting into the fuel system at some point. Obviously there are only three possible culprits. The O-Ring on the water separator appears to be good so this leaves the fuel selector and the fuel sender as the only two possible issues (unless I am missing something). Obviously I can bypass the fuel selector/water separator to rule these two things out however it appears that I can't get the fuel sender out without unriveting the hull? Is this correct and how likely is there a problem with the fuel sender?

Well, I just read on another thread, that this user named BlueFishCrysis took apart his whole engine and did a full, rebuild on his SL 780 Fuji engine and found that the clear fuel lines were too thin and the stainless clamps did not have a good enough hold on the fuel hoses.
That could be the issue perhaps. He used thicker, black rubber fuel lines to fix this. I used those on my ski too, but I used them because they are more durable.

If you want to remove the fuel sender you will need to unbolt the tank and slide it forward.

you should pressure test the system, leaks are easily found that way.

It could be something as simple as the inlet/outlet check valves not working properly. Like pete said, pressure test the system. The pressure relief should open at around 2.5 PSI
