I'm finally swapping to MikeL's 6sp trans cooler, and I remember reading his fuel cooler advice. The idea was to move the stock Allison cooler up above the new Setrab, and run my fuel through it. Can I just run down to the Parker store and scare up the above fitting, or will it leak? I seem to recall that the stock fitting is o-ringed and uses a washer, but I am running 12psi not 300 Will this be ok, or am I going to leak? Thanks in advance! - Wally
