Fuel line for 2000 GTX DI

[nhmort]

I'm looking for the diameter for the fuel hose for my 2000 GTX DI.

I've read about replacing the gray Tempo fuel lines and I believe that I have them. The tread that I've read is for the carbureted model. My ski is up at our lake place so I'm going by memory.

Does anyone know the diameter and how long I need?

Thanks, nhmort

Nope not on a DI ski. You have high pressure lines with fuel injection type connectors. Is your ski running good?

Starts up great and runs fine all the way up to about 5900rpm. It get a maintenance flashing too. The learning key stops at 4900rpm with no problems.

I'm going to change out the fuel filters.

We put ten hours now it over the Fourth of July weekend.

I read all of the posts about the GTX DI and the potential problems.

I'm going to keep the battery topped off with a trickle charger.

The previous owner used XPS oil and 91 non-oxy gas.

Any other ideas?

You should be getting 6900 to 7000 rpms.
Try this, crank the ski on the trailer with a volt meter attached to the battery. Rev to approx. 4000 rpms and read the meter. Should be reading at least 13.5 volts. Anything under 12.5 or over 15 volts means the rectifier is bad and needs to be replaced.

Thanks for the response.

I'll check that the next time I get to my lake place.

Thanks for all of your help.

As noted above, you do NOT need to replace the fuel lines. Yours are entirely different than the Grey Tempo lines that have issues.

Guys, thanks again for all of your responses.

I replaced the rectifier.

Same problem.

Does the the jet ski start and run to 5900rpm if the fuel pressure isn't up to its fullest 107psi?

Any other suggestions?

I realize that I need to get the codes read to pin point what's really wrong. My concern is that I'll get some codes and throw some parts at it and I still can't fix it.

I pulled the plugs, mag looks good and pto seemed a little oily wet.

You are probably getting good fuel pressure for it to run good up to 5900rpm, but would not hurt to check. Air pressure should be 80psi and the fuel should be 27psi over that creating to magic 107psi number.

Download a manual if you have not already and read the engine management section. If you can get the codes read, the code chart will be in that section and can be interpreted.

Check the compression. Both cylinders should be reading about 135psi. Hopefully compression is good on the pto cylinder. Maybe it is just a clogged injector.

Crank and run the ski for a couple seconds and then push the stop button while listening for two air pressure release sounds. That is the sound of the rave valves cycling or wiping. If you don't hear that sound then the rave solenoid is probably not working. Rave valves should be opening around 5000 to 5500 rpms. The problem you are having is close to that rpm so it is worth a check. If you have not cleaned the rave valves recently I would probably go ahead and pull the and clean them. They should be cleaned about every 50hrs.

I have the manual. Going to get the codes read soon.

I've cleaned the RAVE valves and I can hear the clicking of them after the engine has stopped.

Do the RAVE valves open all the way at that rpm to give you the last 1000rpm?

My compression is 128 on both cylinders.

128psi is good but not great. It should still run like you want it to.
Yes the rave/exhaust valves keep the engine power curve from dropping off drastically. Glad the solenoid is working.

I am just guessing but, when you get the codes read look for P0202 or P1101. Those codes pertain to the pto injector. Oh yeah, also look for P0116. Water temp sensor out of range.
