Awesome! According to the box in the picture, that is a Derale 15727 kit. According to reviews, people have had trouble with leaks but you got it right on the first try. I can't tell from your pics where you mounted it. Can you describe it? I'm sure I can find a place but am interested in what you decided on.
I mounted it forward of the stock location, on the frame rail.
Are you worried the toggle bolts will rust? Those aren't normally made for outdoor use. Perhaps you purchased stainless steel?
I honestly didn't think of them rusting. I used these to mount the bed rail in my truck. I wasn't at all happy with the stock bolts and nuts they provided for install.
I see that this kit uses the ubiquitous "Ford" PH8 oil filter, which many say is a great filter. Seemingly it would be better than the small filter RAM put on these trucks. I can't imagine that the OEM filter is a problem (think future warranty issues if it were!) but the PH8 has been around a long time and I don't remember reading of issues with it.
I wasn't sure what filter to use, I brought the adapter to Auto Zone and just started screwing filters on in all honesty. This filter is indeed larger than the stock one. I also took into account the extra hose and larger filter so i added 1/2 quart extra to my oil change.
Did you note your before and after oil pressure?
I didn't note the before pressure, I didn't have that gauge set up in my cluster. I do now, and under normal conditions it is just over the 1/2 way mark.
