marinco plug question

hey guys I have had the marinco block heater plug mod on my truck since last year and the flap that covers the plug used to stay closed while driving and when sitting still. Now for some reason this winter it will not stay closed at all?? It never happened last winter so I was just curious if anyone who has this mod has had this happen and what did they do to make it stay shut??

Thanks,

-AJ

Yes, this happened to my Marinco plug soon after installing it. Just take an old injector o-ring and place it on the portion of the cap that closes onto the plug opening. You'll see a groove where the o-ring will fit nicely as you push it all the way down. Works great!

Thanks for the tip. I was actually thinking that but then I didn't know if it was going to be too thick and not fit anymore

I used some black RTV and put it around the edge of the flap. I let it skin up and closed the flap. It opens and closes with no issues for over a year now.
