    I've just started noticing on some steep hills, passes, my truck has been hesitant. I'll be charging up a hill about 2500-2700 rpm, i've got 4.10's and 35's. And every once in a while the engine surges, like it's running out of gas. Could this mean I need to replace my fuel filter? Or would it be the cause of something else. It only really occurs when its under load up a hill, just more sluggish then usual. /forums/images/graemlins/truck.gif

    I would start by changing the fuel filter, couldnt hurt to change it anyway. If that doesnt fix it then check out the carb. It might also be that there isnt enough gas in the tank and it is moving away from the pickup tube.

    I had a full tank when this was happening, also Im about to put a new intake manifold on. SO when I got the carb off, what should I be looking for? /forums/images/graemlins/truck.gif
