Fuel pumps don't need return lines at all; EFI fuel systems do.
True, but the hot fuel system for the later 460's had a return even though the engine still was carbed. The problem had been fuel vaporization so Ford put a small bleed in the system to take off vapors and return them to the tank.

I am also thinking the electric pumps on the early 460 trucks could not be dead-headed on their output, but I am not sure about this. That could be another reason for the return, besides circulating the fuel to keep it cool.

Yes, there is one style of pump that can't be dead-headed w/o problems. Don't remember which style it is, but that might have been either the reason or part of the reason.
Having said that, didn't Trav point out that the pumps for the 460's were the same as the ones for the 400's? The ones we hadn't seen before? And, didn't Demeron say somewhere, although I can't find it, that his truck has a return? You may be right about these pumps not liking dead-heading.
yeah my pump had a return, you can see it in the video I posted. I was wondering if someone could point me out to where the oil pump is, I was driving it today just down the block and the oil pressure was high, and it was smoking blue smoke, so I didnt want to drive it too far. i would just like to check to see if everything is hooked up to it correctly
The oil pump is in the crankcase, and you didn't do anything to it. Couldn't have. However, blue smoke does indicate oil. But, could it have been black, which would be the carb? I could easily see the choke being stuck on.
okay, where is the choke lever? is it on the left side of the carb as you are looking at it from the front of the truck and isnt it automatic? it seemed like it was running a little rich. do i have to take it somewhere to be adjusted if that is the case? I am close to gettin this thing back on the road!
I've forgotten what carb you are running - if I knew. But the choke control is a round black thing on the left side as you say. Most have three screws holding them on and can be turned slightly to adjust them by just loosening the screws. Note where the index mark is as compared to the scale in case you need to get back there.
But, is your choke electric or does it have a tube coming up from the exhaust manifold? Many of the tubes have corroded of and no longer bring hot air to the choke so it never comes off. In that case we'll need to discuss hooking up the electric heater, assuming it has one. Remind me what carb?
that would be my problem! I had a hose that had a hole melted in it in the fire. I will fix that and i should be good as gold! They were some old hoses and needed replaced anyway. thanks again gary! you have saved my butt a few times on this thing!
Congrat's! It now sounds as good as it looks, and that is saying a LOT. By the way, where did you get the wheel lip trim? It looks like stainless. Oh yes - what did you do to get rid of the smoke?
gary- i patched up that hole in the hose that connects to the choke from the exhaust, I just cut out where the hole was and put in a splined hose connector. I bought the stainless steel wheel trim off of LMC truck it was around 150 for all of them. that is where I got most of my things for my restoration, also Jeff's Bronco Graveyard has a lot of cool things too. I used both web sites to get the best deals.
I really appreciate all of you guys helping me out throughout this. I have learned a lot about my truck, now I can say I had one of the only 82 400 fords with electric fuel pumps, but I switched it out
