    Polaris slh 700 fuel line

    Hi was just wondering if anyone had installed a manual hand inline fuel pump to there ski at all. I have problem starting mine and it sometimes drains the battery it takes that long to pull the fuel through. Could anyone advise me weather this can be done or if there is another fault possibly. Many thanks

    Do not install a fuel primer bulb in your fuel line. If it is not pumping fuel, there could be a number of causes. Check engine compression. If you have a cylinder down, that may not allow the fuel pump to operate correctly.

    Check the pulse line from the engine case to the fuel pump

    Check the lines from the carbs to the tank and everything in between. Go through the entire fuel system, carbs and all. The problem will most likely be found.

    I have replaced all of the fuel lines as someone on here recommended to me. I have removed the carbs and they are now being cleaned. So hopefully that might solve the problem but just wanted to see if it was possible to fit a primer but obv not. Thanks

    There is no need for a primer when everything is right on these. They are all normally easy starting motors.

    There is a lot more stuff to check/do.

    Yes, the carburetor rebuild is a very good thing to do. Highly recommend NOT using aftermarket carb rebuild kits. Buy the genuine OEM Keihin carburetor rebuild kits. A Polaris specific kit is available from Watcon

    The fuel selector valve should be replaced. You want to ensure there are no AIR leaks anywhere in the fuel feed, all the way from fuel tank to engine.

    The pulse hose from engine crank case to fuel pump should also be replaced.

    Use high quality fuel hoses. I prefer reinforced marine grade fuel hose, not the clear or tinted thin fuel hose.

    He is dealing with Keihin carbs not Mikunis. John Zigler also has Keihin carb kits.

    Do spend some time looking through this info.

    Pulse hose can be found low on the left side of the engine. Goes directly from a nipple on the side of the engine crankcase up to the fuel pump section of the carburetor.

    Would it have originally have been a black hose?
