Re: Fuel tank for First 42
I regret that I have not responded sooner but, these daze, I don't visit this site too often as the BS Coefficient is nearing unity and I have neither the time nor interest to bother with it.
N'any case, there is no "easy" way to get at the fuel tank in the First 42 short of removing the engine and getting at the securing tabs through the fore'n aft inspection ports in the sail locker on the starboard side, the forward inspection port on the port side (unfortunately often blocked by the placement of the hot water heater) under the quarter cabin berth and, aft, through the port lazarett locker which will require maneuvering over and around the steering quadrant. (Frankly, I don't know anyone that's managed it.)
If you are certain the tank needs "polishing", one approach is to fill the tank with fuel and a good treatment such as BioborJF, let it sit for a few days, then "polish" the fuel by threading a 1/2" "pick-up" line through the fuel filler tube and attaching a return line to the fuel pick-up fitting on the starboard forward lower corner of the tank (behind the engine) after disconnecting the fuel line to the lift pump. By recirculating the fuel through a couple of filters for a day or two with this arrangement, you should be pretty good to go. Putting together a fuel polishing system consisting of a fairly high speed pump coupled with a pair of Racor filters (say a 30 Micron leading a 2 Micron) bolted to a mounting frame really isn't/won't be that costly and should do the job nicely. There are other approaches but the foregoing should work.
