clean fuel system
You'll save alot of bucks pulling the jetpump yourself and letting a pro set it up,
and re-install it yourself. give him the coupler bearing & driveshaft so he can check for true. You should update the fuel delivery system & clean the carb filter out. Replace the fuel selector switch with a plastic one.
A good tech will check the splines, new impeller bearings & oil. Get new rubber dampers too. Maybe an anti-rattle kit.
To REPLACE FUEL LINES
Tempo fuel line was used on all skis from 1994 thru 2002. Seadoo 587's-717's = 25'of 1/4"fuel line, 787's-957's = 20' of 1/4" and 5' of 5/16"fuel line.
First, remove the negative battery cable from battery then siphon and empty any gas from tank.
On 587's, 657's, & 717 skis, cut the new 1/4"I.S.dia. gas line one piece 12" long, two pieces 24" long, two pieces 60" long.
Remove the fuel selector switch by pulling the center plug of the fuel dial with a needle, and remove the phillips #2 screw,
and wiggle & pull until the knob pulls off. Then unscrew the 22mm plastic nut, washer, and push it thru the hull, into interior
compartment. Next, under steering and in front compartment, useing a 10mm ratchet wrench, remove the nut on top of the separator
filter's bracket to free it. Cut all the old fuel lines about 2" away from each part, and set aside. On top of the fuel tank is
a four line bafel top. Look for the vent line and pull that up and off, it probly will come easily. Make a mental note of the
zip ties to the lines as you will tie everything secure from bouncing around when you are done. Next, cut the three remaing lines
2" above the bafel, and pull them up and off as well. Next, undo the two rubber strapes holding the gas tank down in its position,
then unclip the fuel bafel two wire electrical connector. Unhook starboard oil tank strap. At this point you could attempt removal of the bafel from tank,
or wait and grab the emty gas tank from frontside and remove from the ski thru the compartment hatch, and you mat be able to manuver
it out along with the tank as a unit. Remove the fafel by loosening the lower gear clamp and pulling the bafel up. A circuit board and
a float with a magnet on it is inside the bafel and sends a signal to the MPEM and gauge as to the fuel level. The bottom of the bafel
has a clip/screen, you should remove and clean, and look at the short and full lenth fuel straw in there. The one that is at bottom
where the clip/screen is, is the RESERVE. The one thats about 1 1/2" short is the ON straw. Mark the On & Reserve spigot tube at the
top of the bafel on each tube. Even draw a circle front of the tank bafel with a majick marker of the two wires and four tubes. Mark the O & R on
your drawing, the two other tubes, one is a vent line connection, the other is the fuel returm line from carb & returns unused fuel to tank tube.
Remove the Carburator Air Box to gain access and remove the supply and return fuel lines from the carbs, and discard them. Next, clean
out the fuel tank (use a rag swab on a slim rod) Clean the fuel bafel, disassemble the fuel separator bowl and filter and square O-ring. You
have a tank that once the bafel is out, will fit right thru the front hatch
to clean it out good. Bills86e
