I first thought that I had a fuel issue so reading online I replaced the drain valve o-rings and the fuel filter. This seemed to stop the spray I saw out of the filter cap. I left my truck sit for 2 months and only started it a handful of times. Checking my leak and it remained. I then noticed my coolant to be gone from my reservoir. After looking under the truck I can see where i am leaking coolant out of the main pulley but don't know it that is the root source. Any help would be great not very mechanically inclined, thanks.
