I've read through numerous search returns, and am begining understand the value of installing a fuel / water separating filter. I have a 98 4Winns Horizon QX with 3.0L VP/SX drive. My confusion is currently on "type" of installation. Sierra seems to provide a few options and I'd appreciate any feedback from any of you that can indulge me here.
-The inlet/outlet size for a suitable model, should be equal to that going to the fuel pump (I would expect..correct?)
-The higher the microns the finer the filter... but can too much be a bad thing? I'm wanting to separate just the water. The fuel pump has the ceramic element and theres the metal element in the carb. So a 10 micron would be adequate? I want to ensure that there will be enough flow as some of the units I've been searching rate on an engine being >200hp or <200hp rather than flow rated (which would be matched to a given application)
-The installation... I read a bunch about being higher than the tank to prevent syphoning. Should it be as close to inline elevation-wise with the pump as possible? (instead of the tank?) Pump is higher than the tank anyway.
what has caught my eye is the Sierra Kit w/Aluminum housing & Long Filter pt# 18-7775-1 (it expresses for Engine Type 200hp and above, 3/8" Inlet - which I still have to verify, but I think is what I have on my pump)
