FFB,
For what is worth.....DON'T DO IT!
Did that very thing this past summer. Rec'd a 330 gallon fuel oil tank w/ approx 85 gallons of #2 diesel ( & water) for free! I managed to "pull" about 45 gallons of fuel out of it. There's a good 5 gallons of water in what I pulled out though!!!!
In my case, the tank was and is useless!!!! I wasn't comfortable with the fact that there was alot of debris from rust and dirt and though I tried to clean it out, it wasn't worth the risk of ruining my new tractor!!!
Go online on Craigslist and find yourself 2 (or more) 55 gallon plastic drums. Should cost you around $10 - $15 a piece. Wash them out & dry them out and you are set!!! I got the "white or clear" plastic so you can see the fluid level.
That's what i did (2 for $24). Washed & dried them out and transferred the 45 gallons into 1 of them.
I went to Harbor Freight and got a $25-$30 hand pump (rated @ 8 to 10 gallons per 100 rotations), went to TSC and got a Goldenrod fuel filter (water block), added an 8ft. hose and some fittings......I'm set!! Have it setting on a pallet out of the weather so it is accessible and I can use my forks to put it in the truck to go fill it up at the station. Not a bad setup, and its relatively cheap!!
If you're adventurous and have the tools/welder, weld a nut on the end of the crankshaft or make an adaptor and use a cordless drill to pump your fuel.....works pretty well!!:thumbsup:
