    Hi Guys,
    Any tips on fixing leaking gasket on Lethal/Moroso intercooler tank cap? I tried tightening the screws, but coolant is still weeping out.

    Sounds like it's being pressurized. I had the same issue until swapping I/C mani tube orings

    He's referring to the O-rings on the pass through tubes going into the intercooler below the blower. If they fail it allows boost pressure to pressurize the intercooler system. If they are factory original it would be a good idea to replace them. You can get them from Ford but they want a small fortune for 4 O-rings. Standard #115 O-rings will work. 7/8" OD, 11/16" ID, 3/32" width.

    I changed the filler neck out on mine, it uses a screw in cap, I'll get a picture of it and the brand when I get home from work today

    Nice, my tank cap is always a pain to remove and would love an easier option. After replacing the cap surround plate and gasket I got a replacement cap but it must have been a chicom knockoff because it didnt seal at all.

    good find. Mine is brand new and it's a piece of garbage. It literally gets stuck every single time I want to take it off and I damn near have to break the damn thing.
