My 370SS has no fuel shut-off valves that I can find.

How do you take the filter out without fuel flowing from tank into the empty housing? I don't want to pinch the hose, so what's the alternative?

Putting a cup of gas in the bilge is NOT cool.

Provided your engine mounted fuel filter assembly is higher that your fuel tank, you should not have any fuel flow up hill from the tank to the filter assembly unless you activate the electric fuel pump. Keep the key in your pocket so nobody accidentally turns it to the on/run position while you are working on the fuel filter assembly.

I took filter off in the winter and fuel filled the housing as I reached for the new filter, squished fuel out into bilge then.
It must siphon from tank.

Was your key turned on? Shouldn't be any leakage, if the fuel system isn't pressurized. If you have a Schrader valve on your fuel rail you can release the pressure that way or just have a small bucket or container ready. Cut the top off a gallon milk jug use as a catch can. Place around the fuel filter. As you unscrew any leakage will just fall into the container. Eventually the fuel filter will just fall into the catch can as well. BOOM... no fuel in bilge.

BOOM... no fuel in bilge I see what you did there.
No key on.
Filters are in a bowl beneath a cover with 3 bolts, that bowl is connected to tank via 3/8" hose with a route that would let it siphon from tanks.
Planning to pinch hose, run engine to stutter, then pull the cover on the filters.
In the fall I'm installing a set of valves on the fuel line somehow, no fuel tank should be without a shut off.

I don't think this should happen. Our boats came from the factory with anti-siphon valves that prevent fuel from siphoning from the tank and filling the bilge in the event a fuel line is cut. Yours is either sticking or someone has removed or disabled it. You can order new ones from Florida Marine Tanks who supplied them to Formula. I recently had a fuel pickup problem and ordered new valves along with the pickups, I think the valves were $15 - $20 apiece.

Are you certain there is no valve to cut off the fuel? Have you found where you can access the top of the fuel tanks, where your pickups exit, and your fuel level senders are?

Update: There are no manual valves, I tracked the fuel lines back to tanks on both motors.

There is an anti-siphon of some sort that works on Starboard tank/motor but has failed on port motor.

Following the instructions for the Gen 2(3?) Cool filters I relieved pressure, took the keys out of ignition, and had my son manage the fuel filter while I put my finger in the "dike" that was the running from the port tank. One or two absorbent New Pig pads and the engine, bilge, and needle nose pliers for disc filter were spotless and fuel free.

Fall project will be to access the ant-siphon valve and fix it.

Spent the night on the hook for the full moon, boat ran flawlessly and the Cabernet my wife brought was excellent.
