Re: Fuel filter change
Fill the filters with fuel prior to reinstalling them to ensure there is indeed fuel in them when you fire up the engines. The fuel pumps are lubricated by the fuel and if they run dry for just a few seconds, you shorten their life drastically. Have everything ready before removing the filters. Rub some engine oil on the filter seal, this will make it easier to get it off the next time. Put the filter on hand tight only, do not use a tool.
Oh, and ventilate ventilate ventilate!!

Re: Fuel filter change
Cut the top off a white plastic jug to dump the fuel out of the filters. When you do this, check what comes out. Any water, sediment, or discolouration will give you an indication of what's going on in your tank.
When you're done, open up your valves again, look for leaks, clean up any fuel that went into the bilge, get rid of anything that came in contact with fuel, leave the engine hatches open and turn on your blowers for at least 5 minutes or until you can't smell fuel anymore, then start your engines. After you've run the engines for a while, shut them down and look for leaks again.

cpoint wrote:Source of the post I need to replace mine as well, I am getting the fuel polished tomorrow because the rpm is going wild and port engine cuts off, will come back online and after brief time does it again. All indications with everyone I spoke to said bad fuel. So figure I will replace the water separating fuel filter. The company cleaning the gas will not touch it. So where exactly is the fuel shut off valve for port engine? This is for 2000 356 carver aft cabin. Thanks
Why bad fuel? Has the boat sat for years? Have you diagnosed properly yet before going through the trouble/expense of polishing? How much fuel are we talking about? What did the contents of the fuel filter look like when you replaced it? I'd be hooking up each engine one at a time to a remote fuel tank/jerry can first to see if you get the same symptom. If you do, it's at the engine end. If you don't, it's before the engine but it could be other things as well such as bad anti-siphon valves, clogged vents, clogged tank pick-ups.....
Would hate to see you go through the expense of polishing and still have the same problem.
Again, ventilate and don't keep the portable tank in the engine compartment while doing this.
