Update (long, but maybe will help someone) -- good recommendations Skeester - but, saw this after the fact: Spent a few hours pulling tank yesterday (alone) - left boat in water - first thing I had to do was lose a lot more fuel than I thought was left in the tank; Gauge said empty, but I ended up siphoning almost 18 gallons of fuel (that's over half a tank!) -- I have two 14 gallon gas caddy's that have wheels on them, so I put one on dock thinking I would siphon directly into it -- wrong. The dock was not low enough from bottom of tank, so after thought, I took a 5 gallon gas can with handles, tied a rope to handle and other end to toon - it sat in water and was low enough to siphon into - I only put about 4 gallons in at a time so as not to overfill and get gas into lake - then I would pour contents into the big gas caddy. I had to do this about 5 times, and on the last time I was able to get a pole through hole for hoses from engine to tank area, and under tank, which made all the fuel go to one corner and I was able to siphon the last bit out. I just took a screw driver and small hammer and chopped rivit heads off to free the mounting bar and undid all hoses. I had to cut the fuel fill hose as it was so short that I could not get off either the boat or the tank to free the tank up (ordered another for 13 dollars) -- then I kept hitting things when I tried to lift tank, so I ended up having to remove the latch for the sundeck over the tank (it was also rivits, and did the same thing w/screw driver and hammer) - had to remove two screws holding the shock arm holding the sundeck cover over the tank and let the shock hang free on the bottom of cover (this allowed me to let the cover go further back for clearance, but the hinges stopped it from going all the way back (good thing) - then I had to remove nuts and back out about 4 or 5 screws in toon railings that would not give me clearance to pull tank. Finally was able to get tank out. Today I was able to remove the fuel inlet by putting vise grips on flat not next to tank - then I put a 3/4 open end vertical on the square fuel inlet, then put a small breaker bar through the closed end of the wrench (also sprayed it with PB Blaster and let it sit for an hour) - it was tight, but got it out - it actually looks fine, and screen is still attached - the screen does catch when you try to pull it out, so you just have to snatch it through and if it breaks or screen comes off, you fish it out through sending hole - mine came out intact. I am going back with a Moeller flexible one with a spring inside and a screen on end - you don't trim the bottom and the shortest is 22 inches, but it's ok because it just lays flat on bottom - I decided to go with this as I want the screen since I've decided not to put any more filters in-line until I have it on a trailer in fall. I am replacing the sending unit with a Moeller 16.5 inch reed switch sensor (tank is 17.5 inch deep) - putting new gasket in place. I cleaned tank real good earlier today with pressure washer, both inside and out -- both are really clean, and tank is drying out. Once parts are in I will install, add a new anti-siphon valve, and re-install and put 4 new rivits in place of the ones I removed. I have a new fuel line with bulb to go from anti-siphon valve to engine cowling (outside) - I will replace any lines inside the cowling once I pull out in Fall. I will leave the vent hose because it is clear and is in good shape. Hopefully will finish up and drop back into toon in a week or so - in meantime, I have a 12 gallon temp that I put into hole the tank came out of - just will be a hassle to put fuel in, but not that bad. Thanks all for the great advice, and maybe others can find this thread if it relates to their need.
