    Just traded for I think 1994 SL 750 what should I do first?

    He said it was a 95 but the last digits on the hull plate are 94.

    The guy said it would idle, but go dead if you tried to give it gas.

    Said he replaced the fuel pump to a triple flow. Some one told him he would have it re-jetted since he went to a triple flow fuel pump. I don't know if I believe this..

    Its been siting up since last year, should I drain the gas?

    Welcome to the Hulk.

    If the HIN ends in 94, it's a 94.

    Rejetting is NOT required when installing a triple outlet fuel pump.

    Drain gas, yes.

    Read up on your new find.

    Thanks guys this is an awesome forum. Lots of info

    I do have a question, after reading several post thiers talk of a fuse in side the electrical box if blown could cause the problem the previous owner had. I checked the fuse and it is blown. The fuse is about 1 1/4" long and one end it says BUSS AGC 1/4 on the other 250V, is this the correct fuse? What amp fuse is this?

    Those 1/4 amp fuses can be obtained at Radio Shack for about $2 for a 4-pack.

    Also, unless the MFD is really whacked (i.e. messing with CDI and/or LR modules), it won't cause the dying issue you mentioned. A ski that idles then dies when you hit the throttle is one that is not getting enough fuel.

    XLint is right, no jetting changes are needed for the 3-outlet pump. The only time you need larger jets if you put on easier breathing flame arrestors or other similar changes that cause more air to flow into the engine.

    Defintely follow K447's links and run through all the checks for a 750. Replacing the fuel lines, cleaning or replacing the fuel selector, and proper line routing is essential for these engines to run well. Also, be sure the fuel line restrictor is in place. Without that little guy your fuel pressure will drop and cause delivery problems.

    However, you CAN disconnect the MFD connector from the back side of the display. The engine will run just fine without the MFD plugged in. You won't see any warnings of course, but you can verify whether the display is causing any engine trouble.

    See the MFD link from my signature for more info.

    This weekend I was able to to work a little more on the ski. I stop by my local auto parts store and a Polaris dealer and neither one had a 1/4 amp fuse. Should have listen to John to start with. Went to Radio Shack and picked up the 4 pack for $1.99. Started inspecting fuel lines. Drained the gas tank and when I unscrewed the cap for the fuel lines and pulled up the lines had disintegrated. I pulled the gas tank and poured out the pieces. The guy I bought it from said the reserve did not work, I guess not, the dadgum line was crumble in the bottom of the tank. Now do I need to pull the carbs and all hoses and clean and blow out every thing? The filters on the end of these lines look toast. My local polaris dealer wants my first born for replacement parts. Is their a resonable parts dealer on line?

    And rebuild the carbs.

    There really is a lot of useful info in my signature links.
    Start with the Fuji engine section, and the new-to-me Polaris sections.

    There is also a Parts Sources section

    Agreed. If that junk was in the tank you have to work from the assumption that it may have reached the carbs as well.

    The fuel intake screens can be revived by soaking in carb cleaner and scrubbing with a fine brass brush.
