I made my own front inlet thermostat cover. If any one needs one I have a few extra covers and I can get some more 2" aluminum pipe. Best part is if you flip the upper coolant hose it almost lines up perfect and all you do is cut off about 5" of it.
This will not fit with a dual fueler but makes working on the truck much easier. I got sick of messing with that damn hard pipe and cutting o-rings when it had to be reinstalled.
Does anyone know the size and thread pitch of the check valve. I cant remember what it is.
