Hi all.

        I have a 3 oversized drain plug on my 351C and it still leaks. I want the drain plug to be magnetic. I've seen the rubber plugs that expand to seal, but they don't have magnets. I want something that looks stock and has a magnet. Any ideas? Is there a 4 oversize? I don't want to change the oil pan as it is original. It would be great if you could send me a link I could follow if you have a solution.

Also, I broke my Teflon oil line for my pressure gauge and don't want to replace the entire line. I found this in my parts bin but I don't know where I bought it. It's one time use only. Could someone please lead me in the right direction? Thanks!IMG-6584.jpg

You can use the union, just get some new compression olives (or sleeves)

If you don't want to pull the pan to replace the weldnut inside, maybe run a tap through it for the next available size. A little grease on the tap will catch most of the chips, the magnet will usually get the rest.
