    Oil pump prime

    175 optimax pro xs
    sn 1B698699
    I've read it a couple of times here but I'm assuming 1 prime sequence is more than enough to take a dry oil pump and purge all the air out? I get a little nervous when it comes to oil. When I started it (the prime) it was kinda loud and I heard it when the oil hit it...looks.like it dropped the reservoir about 3oz that the manual said it should.

    also lets say someone were to feel more comfortable using the power tune on the lines to ensure they stayed put, but has already put them on and performed a prime. is the best course of action to take it out and run it for a few to clear the oil in it then redo the connections? or am i over thinking things and the zip ties are fine?

    If you feel you need to disconnect lines, run the engine for a few minutes (even if it needs to be on the flush attachment).

    DON'T run multiple oil pump primes without running the engine in between.

    One sequence (performed properly) is sufficient.

    okay so a flush attachment run is enough to clear the crankcase? or at least clear it enough for another prime?
