mine has 1 for each engine that looks like original equipment mounted forward on the bulk head. they are all rusted and i cant even get them apart. then there are 2 more mounted in the rear of the engine comp. those look new. like only a few years old. is it over kill to have 2 water sep. for each engine? i think it is.

Mine has one for each engine which I think is adequate.

I have 1 with 1 engine, so +1 on the topic here.

One per is the norm . 2 per is ok if run Parallel w/switching valve . 2 in series could be to restrictive for the fuel pump .

1 water sep per engine + 2nd fuel filter per engine (diesel here).

One per is all you need. Increased vacuum with 2 per, extra fitting restrictions etc., in a hot engine compartment and you risk vapour lock (gasoline here )

mine is original aswell one for each engine and one filter on each engine after the fuel pump.

thats what i thought. i think the other owner most likly couldnt get the old ones apart ( i couldnt ) so instead just add 2 new ones. i done get some people. why didnt they just cut the old ones loose and add the new one in there spots? good lord....
after its all said and done the boat is going to be 1000 lbs lighter. i have pulled a 5 gallon bucket full of wire that went no where, 2 fuel/water sep. tons of old parts stored in what ever hole they could find to shove them into. ect.....sheesh

If your fuel pump could handle it ( gas fuel pumps don't like restrictions )

But if you did 2 it would be 20 micron then the 10 . don't forget you may have filter on the engine also . ( could be in the carb) . I am running a 30 micron racor 900 and a 10 ( I believe) on the engine . common set up on a diesel , also some times 2 off engine filters are used on a diesel .

I have one water separator mounted on the motor and two oil filters also mounted on the motor...............John

My boat originaly only had canister style fuel filters mounted on the engines ( Crusader ), I added fuel seperators in line at the fuel tanks with shut offs on both sides to make changing the seperators less of a mess and left the original filters in place.

I took my glass bowls of this week & installed new spin ons. My boat came with 3/8" copper lines with flare fittings. I had to replace the lines for more length. Replaced with new copper lines & flare fittings. Your rubber lines & hose clamps make me nervous. i don't think they're Coast Guard approved.
