bought 9 gallons today,
the longer line is the return line. the fluid will sprut out the fitting with the elbow so i added a 3 foot section of clear tubing coiled it into a drain pan, then rotated the long hose vertical and stuck the funnel in it, slowly poured the fluid in, it took 5 gallons ( including draining the pan ) to get it to come out good n red. took me about an hour of pouring with the engine idling..... did i say i was pouring real slowly ?.

I'll drain the pan after a week and take a look

Planning on installing a external cooler in a week or so, most likely get one from auto-zone as their website shows several that will fit my rig. I post about it.
Thanks for all your help.
