    defective genuine walbro pump need help and or feedback

    hi all,

    a Friend of mine bought a walbro GSS342 at a local dealer. Installed it and set the rrpfr to 45psi, everything seemed good. Then he put the ski in the water and after starting acceleratin like 4000rpm, the jetski start to act like was lean on gaz.

    Then he looked at the rrpfr and it was going up and down, and hearing pump dying.

    He called lemoine and apparently he said that the walbro pump are weaker thant the oem's one and to not use it.

    I was very surprise as I see that in the USA you guys are using walbro pump with apparently NO issues. So need help feedback as I bought myself one but didn't install it yet.

    Walbro sucks IMO. I went through two before tossing it in the trash.

    Sounds like a fake Walbro. Have not had any issues out of mine at least not yet. It is a tiny bit louder but I can only hear it until my motor starts haha. Tons and I mean tons of people are using the exact same pump in vehicles with great success as well.

    stock fuel pump is where its at. long as the AFRs are good theres no need to upgrade it... if you need more fuel try a BEGI setup...

    Suprised to see so many Walbro failures and sceptical to the origin and authenticity of the pumps. Summit is kind of the WalMart of aftermarket parts and who knows where they purchase 100s at a time from and most likely its the cheapest bidder. We purchase them from a supplier that gets them direct from Walbro and none of us have ever had a pump failure. But still unfortunately with all the copies out there it takes away the security of the Walbro and you really never know what your getting anymore.

    On another note, we have killed and or exceeded stock pumps trying to keep up over 9k with big chargers. In most cases I'm sure a stock will surffice but we never take the chance anymore.

    We need to put together a list of all the popular or usable pumps for our app and list amp draw, flow rate, etc., at given pressures so its easy for everyone to see what they are gaining or sacrificing. Some of the new turbine pumps out there look very impressive but the amp draw is possibly past the safe point when running big injectors at high rpm. Maybe make it a continuos sticky that can always be added to. Just a thought.
