The only vehicle that I have ever owned that had a drain plug in the fuel tank was a
1982 Volvo 244GL ( It came in handy when I got a bad load of gas )
there are no drain plugs on gas tanks, you will have to siphon the gas out or take the tank down to get the gas out.
no
You are supposed to drain your tanks daily, especially if your truck has only two tanks, and doesn't have a wet tank.
in the tanks
This should be on the bottom of one of the two end tanks on the engine side of the tank. There are many different designs of plugs, some of the newer styles are VERY different than the older brass, use a pair of regular pliers on them, drain cock. They still work the same, just twist it and it should drain.
Some types of services that Mr. Rooter provides to the common household are drain cleaning, pipe repair, septic tanks, grease traps, and the removal of tree roots.
If you mean a mixed gas and oil, it may not hurt the mower, it may smoke until this mix is used up. Some mower tanks are easily removed and you can drain the mixture before you use it.
drain the tank, throw it away
Not unless you are having a drain feild problem.
Only wet sump engines have drain holes. Two strokes and four strokes with oil tanks do not, they are dry sump engines.
Most rads have a drain at the bottom,on one of the end tanks. If you can not find it just take the lower rad hose off.
use a drill pump and a chunk of hose
