sounds sketchy but who knows I have crazier things that turned out to be true.
really, ever had moisture in brake lines? compresses! the pump blew cause it couldnt compress the atf, it was too thick.What do you mean compress diesel fuel? You can't compress a fluid, no matter what type. I'm thinking that the ATF ruined the pump for some other reason. In any case, not sure that I would put ATF in my tank. There are lots of other additives out there that are designed for diesel engines that are safe and provide extra lubrication.
trust me ya can. we tried this in one of our race karts brake system, hadnt work. took it around the track once and about lost it on first corner cause it was compressing the water.The moisture in the brake lines compresses because the moisture (aka water) boils from the heat in the system before the brake fluid letting off gas which then is compressed. You can't compress water.
