I have a 72 f600 dump truck and it needs a fuel pump. I am not sure what motor is in it. i think its a 361 or a 391. How do i know which one? Where would be a good place to get a pump, i am pretty sure autozone or my other local yahoo's will be able to get me one!

Don`t think that they are different (361/391) Is it a mechanical on the motor or an electric pump in the tank? Either way you maybe able to use an after market electric fuel pump which I would prefer over the stock unit. Just be sure to follow the instructions wthat come with the unit and mount it near the fuel tank.
Since you have a 600, I have a ? about your brakes
I agree with the posts above...the 361 and 391 should take the same pump. If you're curious about the displacement, though, perhaps the easiest way would be to check the stroke as best you can with the heads on. Put #1 cylinder (or whichever) at tdc and crank it around with a hand wrench for half a turn and get an idea (you won't be exact) of the length of piston travel.
While I've got you here, do you have a dual master cylinder on yours or is it single? If dual, does it have a vacuum booster? I have a '66F600 and I had an experience this weekend that prompts me to consider a dual master cylinder replacement.
Thanks.

Reason: I didn't answer the original poster's question
We might have some investigating to do jointly....I was at the very top of a mountain Sunday and they had this "mandatory" stopping places for trucks at the very top. Don't you know that when I went to stop, there was this cloud of smoke and a sunk brake pedal (rusted brake line). I reached for the e-brake and I knew that was fine, but good Lord!! I don't want to ever have that kind of thrill again.
Oh, the cloud of smoke was the result of the brake fluid geyser hitting the exhaust pipe.
