Ive noticed im losing fuel from the drain plug at a rate of about an ounce a day. Its 100% coming from the plug.

I've tried to tighten it, or hell, even loosen it and it wont budge. Is there a trick to sealing it properly?

Should i use heat to break it loose? (kidding :twisted: )

Run the Pinzgauer until empty, then pull the plug. I do this annually to get any contaminates and water out, plus it's an opportunity to see if the red sealer is coming off. Replace the copper o-ring and use Teflon tape when re-installing. The leak won't go away on it's own.

Do not use teflon tape!! If you must use thread sealer, use non hardening pipe sealant or liquid teflon sealant sparingly :wink:
Teflon tape fragments and gets into the fuel system. I have pulled teflon tape fragments from several fuel pumps :shock:
