Do you have a bum bung?
On the 10-kw through 60-kw TQGs, the fuel drain is located on the skid base.
On the 5-kw, the fuel drain is inside the generator housing near the oil drain valve.
* JP-8 fuel causes the rubber in some bungs to swell. The rubber softens, cracks, splits and eventually leaks.
* Another reason for leaks is that bungs are sometimes installed too tightly. Overtighten a bung and you're likely to crack and split the rubber. Then you've created a leak.
Installing a New Bung
* Make sure the fuel tank and bung are clean and dry before you install the bung.
* Put the bung into the tank opening.
* Coat the threads of a straight adapter, NSN 4730-01-387-7158, with sealing compound.
* Put a flat washer, NSN 5310-01-365-8138, over the bung.
* Insert the straight adapter through the flat washer and into the bung.
* Tighten the adapter with a torque wrench to 40 in-lb.
