- Jul 1, 2013Dan,It is my understanding that due to the fact that we keep a boat in the water 365 days a yr we tend to get condensation in the fuel tank which ultimately leads to many issues. This is common here. There are a few things you can do to minimize the problems like keeping your tank topped up, and adding biocide. What happens is you get condensation, then algae and bacterial grow on the first warm spell, then you go out in lumpy conditions and the crud breaks loose from the tank and begins to try travel thru your fuel system. We use a 2 micron filter o. Our racor so that we do t have to replace the filter on the block as often (a real pain). So, no matter where the blockage is, it is most likely originating from the tank. The process of polishing the fuel runs all of your fuel from your tank thru 2 filters several times and then returns it to the tank under high pressure. The hope is that you can "clean" the walls a bit with the high pressure and then filter the crap out.

Problem is the problem could be any one of many things along the length of fuel line. So, unfortunatlely, you may have to systematically go through each stage/line (from tank to injectore) and verify flow and work your way through. Or get real lucky by guessing. Personally,Fuel Polishing would be last on my list - if you in fact have a fuel contamination problem. Dan

Allison, I had a similar problem about 5 years ago...in my case the problem was with the original oil water separator that came with the boat....the intake line to the separator that came from the fuel tank had a one way valve and the valve was gunked up....I replaced the oil/water separator with better one and haven't had a problem since.....hope this helps....JulesOn Sun, Jun 30, 2013 at 10:54 PM, Allison <allisonleh@...> wrote:
Ok so we have been safely anchored and enjoying the hot weather and swimming but it is time to get down to business and figure out what is going on the the engine/fuel starvation.
Has anyone with a 362 looked at their their fuel intake? The captain says it is very difficult to take the cover off and he doesn't think there is an inspection port on it. His big question is does the 362 have a screen on the uptake? Unlike a typical filter clog, our problem is intermittent. With a filter clog, usually once the engine shuts down it won't restart. When I posted last we were giving it a second chance and we got several hrs almost completely trouble free. A couple times the RPMs began to drop and he we to neutral immediately to take the load off and then he would rev it. It would work so we limped into our anchorage.
We are now formulating a plan. First off we are 60 miles from home:-( so we are missing a lot of tools. We are thinking of trying to get the fuel polished first off. The replacing both filters and the wait and see. The one nagging thing is this whole screen thingy. Jules, Ray do you guys know it the factory installed a screen on the uptake? Any other 362ers please feel free to share your experiences.

> We are on our way to the Deltas for the 4th and after motoring for 6 hrs engine started dying. Fuel starvation. This after reading everyone posting about the fuel shut off valve and me reading abouut them thinking, well ours is just fine....NOT! Evidently after playing with the valve, all is well again, I hope!
