    elbow in fuel sending line?

    Schematics don't show the elbow shown in this pic. However, it was installed as you see here.

    Has anyone seen an elbow in a gravity fed fuel line...and won't this reduce the fuel flow at least at high speeds?

    There is no elbow in any Sea Doo 2 stroke ful lin system, remove the elbow and run the line stait back to the carbs, also replace your fuel line with updated Black fuel line so you dont have a Ethnol fuel problem later

    01 elbow in fuel line

    This motor has been rebuilt 2 or 3 times by the same shop & every time it seized at high speeds. Once before the 15 hour break in ended, the second at 10 hours. Continued problems caused me to purchase a new ski and leave this one as spare. They replaced the motor, the crank, oil pump, fuel lines, etc. I would think that this elbow could limit fuel flow at high speeds and cause it to run lean. Unfortunately I did not think to check before because i paid them to do teh work and thought that with their reputation they would know what they were doing.

    I bought it new and guarantee I didnt' replace anything like this. We only did minor maintenance like battery changes, spark plugs and rave valve cleanings.

    That could be the problem, hard to say though, it could be alot of things, but the techs should have caught the elbow in the fuel line and removed it, if they rebuilt the carbs?????? It could be the root of all your problems, good luck with the job, I would find another shop, just my opion!

    I forgot to mention that the ski ran fine up until about 396 hours immaculately maintained. I took it in only because over a weekend noticed it was slower than my other RX which I bought at the same time (and had similar hours). My other 2-stroke now has more hours on it and runs just fine with no problems. They swore up and down the one I brought in was running properly and was just a slow 2-stroke. So then I told them do a Level 1 on it . When doing the level 1 they notices scoring in the sleeves and replaced them. Level 1 included different needles in the carbs, a carb rebuild, flame arrestors, etc and after they noticed the damage a new top end with milled head.

    I only fill the skis from gas cans which are kept inside and clean and only 93 octane fuel from the same gas station I fill my car at. The gas station is less than 3 years old and I have been filling at it since it was built. Oh, I check and clean the fuel filter every time out. If it's dirty it gets cleaned and changed.

    Do, you have ethonol in your gas there? if so, you need to replace your fuel line, clean your carbs, and tank!!
