Loosing prime?

    Just replaced a pump and wheel motor on a Lazer Z. I thought I had all the air purged out of the system but apparently not. I can get the machine to run and drive great but if it sits overnight the pump looses it's prime and it goes nowhere until I move the sticks around for a while.

    Any ideas?

    Double check ALL hose fitting connections and make sure they are tight.....

    Did you bleed the system with the drive wheels blocked off the ground ?

    I went over all the hoses and checked the filter tightness. The filter seemed a lot looser than when I put it on.

    Everything seems to be good now but I'll know more in the morning.

    Yes I had the wheels off the ground while bleeding. Once all was good I set it down and drove it around awhile and parked it. Went to move it in the morning and it was dead just like it was on first start up. I jacked up the wheels again and bled it out again. Checked all the hoses and filter then. I'm guessing the filter being a tad loose was causing the problem.
