Fuel Polishing Costs
I am about to have my fuel tank cleaned for what I believe is the first time in it's 20+ year history. I haven't found an access hole yet in the tank, so the Fuel Polisher will charge $400 to come to the boat, cut the hole to gain access, pump out the fuel, polish it, and reach into the tank to clean the insides manually, inspect the tank to see if it is in good shape. Then add an access cover, and return the polished fuel to the tank if it isn't deemed bad or "flat" as he put it. If an access plate is found, then the cost becomes $300. From your experiences, does this sound about right? The tank holds 20 gallons, and has about 5 gallons left, if the guage is correct. The Fuel Polisher will inspect the gauge as well. Just need some input to see if this is in line price wise.
If the fuel is deemed bad, ( purchased 2+ years ago when I bought the boat, engine still runs fine ), should he dispose of it, or is that for me to do? If bad, how do I add new fuel at the dock if my marina doesn't allow fueling except for outboards? Do I need to dress in black and pump it in from a jerry can during the night? Ask permission for a one time, 3 or 4 gallon fill to get to the fuel dock?
The tank has a shut off valve on the out flow line, so I can preserve the fuel that is already in the fuel line to the engine, so I won't have to re-prime the line after we are done, but will the air in the pickup pipe have to be primed out or should the Yanmar 2QM15 mechanical fuel pump take care of this?
My tank does not have a return fuel line, but the unused fuel from the injectors is plumbed back into the Yanmar fuel filter on the engine. I could pump the fuel in the line out in order to fully prime the line and tank pickup pipe, but is this needed?
