I think it is easier and safer to remove the bed-[ 6 bolts]- unless you are replacing the tank.

There is no drain plug, so you could purchase a siphon drain from a auto parts store.

autozone sells a cheap little pump thing that works good. its a straw you stick down into the tank and you just crank a little handle and it pumps fuel out

good thats what ill have to do, i just didnt know for sure if there was a drain on the tanks. im gonnna have to pump it out anyway, its 3/4 tank on a 34 gallon tank so you do the math. theres 150-200 lbs of fuel in it plus all the tank and theres no way id be able to tip it up and out without wasting it all in the process.
