New to Quicksilver fuel filter/water separator questions

[model14]

As my restoration continues, I need to learn about the subject device which is feeding the 1988 2.5L motor.

My approach is to check it frequently for water initially and then taper back to every 20 hours or so.

If it fills with water does it prevent fuel flow, or do you get a fuel/water mixture going to the carb?

Is there an anti-siphon device anywhere between the fuel tank pickup and the fuel pump? I was thinking the subject filter may have a back-flow preventer of some type.

Thanks,
Richard

p.s. After changing out the starter and the starter slave solenoid, the engine fires up nicely and idles smooth at 9000 RPM. Everything is going well so far. I haven't pulled the fuel filter yet to see if there is much water in it. Idle time is only several minutes so far.

The filter is designed so water which is heavier then gas floats to the bottom and gas stays on the top. Since this is a restore project and you made sure the tank was clean prior to initial restart, there should be no need to check the filter except at the end of the season. That is unless you experience problems with the engine then yes check it.

There should be an anti siphon valve connected directly to the tank which would have a barbed fitting on it to accommodate the fuel line. The fuel line goes from the anti-siphon valve to the inlet side of the water separator filter. The anti-siphon valve can get stuck and cause problems for the fuel pump to supply fuel, and if it does it should be replaced.
