8.1L Primary Fuel Filter service question

I have a '05 Silverton 340 w/ 8.1L Crusaders. Trying to replace the primary fuel filters for the first time (my first time anyway). I see the hose clamp on the bracket that holds this small inline filter, but the way Silverton has the thing plumbed - I'll have to remove various fittings that are on the wrong side of the cutoff valve. In other words, the only way to break it down is to disconnect the cutoff valve from the fuel hose on the tank side of the valve. Fuel will gravity out from the tank? I can't believe this was put together like this - does anyone have any experience exchanging this filter? Does the filter body unscrew as well? The Crusader explanation for filter exchange is very vague. Thanks - Clay
 
if you are talking about the type filter that is a see thru about 1.? inches in diameter and 3 ish inches long they unscrew from one end....all of this should be mounted above your tank as far as gravity feed is concerned and there should be no gas ''flow'' when you disconnect filter...i would consider replacing that filter with a water separator while i was doing it...
 
That sounds like the correct filter. My guess was that it unscrews, thanks for confirmation. The gas line is below or at tank level from what i can see. My concern would be siphoning of the fuel from the tank when i remove the ball valve so that I can access the filter and unscrew the top of it. Will the anti-siphon valve keep the fuel contained? It just baffles me that more thought did not go into the initial installation so that replacing this filter doesn't require dismantling of so much of the fuel supply line - i.e. fittings, valves, etc. Thanks for the reply
 
to have a gas feed where the tank will gravity feed is wrong and dangerous....good way to get a bilge full of gas if inboard or a fire with an outboard with a broken fuel line.....
 
there is another technical reason on an outboard for the gas line to be below the motor.....i read it on an entry here but i be damned if i can remember it...senility setting in i guess...
 
I'm sure the design compensates so that it will not siphon off. I have seen what looks like a spring loaded check valve on other similar configurations at the top of the tank. I have not looked, but I would bet there is a valve that can be closed at the top of the fuel tanks as well. I'll just have to get down and dirty, remove way too many fittings, replace the filter and put it all back together. Thanks for the help!
