engine airplanes, we have fuel, fuel, fuel, air, mags.
In diesel engines in sailboats it is fuel, fuel, fuel, air, battery
I had significant problems with my fuel system and most were sucking in air problems. My fuel cutoff valve was sucking in air. My pickup tube would pick up something in the tank that plugged the 90 degree turn at the top of the pick up tube and create a vacuum that would allow the Racor to suck in air.
I replaced the fuel cutoff valve and the Racor housing. If the paint
on the Racor is flaking off, it will most likely suck in air. I then removed my tank and cut inspection
plates at each baffle. I then cleaned the entire tank with scraping and completely cleaning
the tank. Then I removed most of the fuel (left about 2-3 inches in order to flush the crap out of the tank) and purchased a high volume diesel pump (10 gallons/minute) from Harbor Freight with a Napa see thru filter. I polished the fuel and tank for 3 hours. Now, all fuel that goes into the fuel inlet is filtered. Knock on wood
, both engines have not quit so far. I also use Power Service
products for bug growth.
I feel for you brother. I have been there done that. Losing an engine in a critical move is very humbling. Try turning a catamaran
on one engine with 3 90 degree turns with a 15-20 knot wind
down the fairway. It ain't gonna happen.
One thing you might try is have a day tank that eliminates all the ships fuel components. If you don't have any problems on the day tank, it is your ships fuel supply. I kept a 5 gallon jug with a fuel line I could drop into the jug for temporary service if needed. It is funny
, the "jug" never had problems. Go figure. I still keep a couple of jugs available for emergency
use when traveling off shore. 10 gallons on one engine will take me 120 miles if no wind
. Hope this helps.
