    Default 2016 Craz 400 Fual filter replacement?!?!

    I saw in another thread you could get a NAPA Gold fuel filter to replace the external one located on the starboard side behind the Cat. I picked one up and then looked at the location of the filter. Wow! I can see no way to replace this unless you pull off major parts. Does anyone have any experience with replacing this? The manual makes no recommendation on when it should be replaced.

    I just looked at this yesterday. I was also surprised by the location. The manual does say to replace every 300 hrs or annually which is why I figured now would be a good time. Engine nut posted in another thread about this and said it's a little difficult to get to... I agree, this is an understatement. The location actually made me think indmar doesn't really think you need to actually replace it until you start have problems with fuel delivery...

    Update! I took the Craz to the dealer for a computer reflash which corrected the “stuck” hour meter. While I was waiting I talked to a friendly tech about the fuel filter replacement. The dealer quoted me 45.00 for the filter and 1/4 hr. labor to install it. I asked the tech how he could do this in 15 minutes! He said he removes the fuel lines at the quick disconnect fittings. Then he snakes the fuel filter with fuel lines connected to remove it. Then you can get to the threaded fittings to replace the filter. Those quick disconnect fitting require a special tool to slide in to release. Also used in the auto industry they are readily available. It might be worth it to let the dealer do it, but my dealer is a 6 hr. drive so I think I’ll do mine this winter.

    If itís anything like an automotive fuel filter, be sure to unhook the battery.

    Typically when you open a fuel injection fuel line, the fuel pump will kick on.

    1/4 hour?? Dang, let them have at it.

    I thought 1/2 to 1 hour was a min time charge for most things.

    A marine pump does not do that. It only comes on for a 2-3 second prime at key-up and then again when the engine is cranking or running. The system will have some pressure though so you need to be careful.
