Bill,
I bought mine with a gunked up tank as well. I did not know what was in it, but here is what we did to fix it -
While the boat was on the trailer, I parked it on a hill and ran one wheel onto a car ramp (the kind you use to change the oil on your car). This put one corner of the tank in the lowest position.
On my 89 18 footer, the tank access is throught the console seat. I took out the sending unit, which gives you a hole about 2" diameter to work through. I bought a cheap fuel siphon from the auto parts store with about 5 feet of clear hose, and added some more clear hose to it so the oultet end was below the tank.
I used a clothes hanger to fashion a guide for the other end of the hose that would get and keep the other end of the hose right in the low corner of the tank. I measured outside and wired the hose up to the coathanger contraption. I wanted to get ever last drop, so this was better than just sticking the hose down the hole.
Sounds like a lot, but with my buddy outside of the boat working the siphon, and me holding the other end directly in the low corner of the tank, we sucked out 15 gallons of contaminated fuel and gunk. (takes awhile!) You could also spring for a more expensive fuel pump if you do not want to wait for the siphon. My fuel had a lot of water and other crap in it that we watched slide down the transparent plastic tubing of the siphon.
I added the same racor, ran it around for 45 minutes, emptied the racor of anything that came from the lines, and it has run primo ever since. I think you are pretty close with your 36 gallons with the poly tank, and that it is the original tank.
Hope this helps, good luck
Ken
Wouldn't a complete flush and a Racor filter do the job ? Why would the boat need an operation ?
