Ok, here comes your forum dummy. As I don't know anything about these trucks. My truck is running rough at idle, lots of hesitation. I have to set the idle high other wise it dies. I've had a few people look at it, and everyone keeps saying that it is acting like it needs more fuel. Figured, since I just got the truck and it had been sitting for awhile, I would stop by and buy a fuel filter. Got the filter. Now here is your dummy question. Where the hell is it at on the truck???? I can't find it anywhere, and knowing my luck with vehicles, the previous owner probably bypassed it.

Also, how hard is the heater core to replace. Mine is leaking coolant into the truck.
