Hi again,
Last time I posted I was having an overheating problem and was considering an oil cooler because I was too stubborn to admit the new radiators I was getting were junk. I finally decided to listen to you guys and got a Griffin radiator that cost me a few bucks but I run at 180 no matter what the outside temp is... THANKS!!
Now I have to deal with resolving my heatsoke problem. I am heading out right now to get the parts for the fuel line mod before my truck catches on fire (it scares me to see gas boiling). I also read another post about making a heat sheild for the carb out of a sheet of aluminum. Looked at the pics of the 74 dart (beauty by the way) and am just curious about how exactly that gets sandwitched in there (specifically the gasket set up).
The last thing I am dealing with right now is that I recently blew the cobwebs off this truck after using it very little over the last year and a half. So for the first time in a while I took it out on the highway for a 300 mile trip. It seemed to get mad at me for making it work that long. I noticed that in third gear at speeds over seventy, the truck started to buck violently. I know it wasn't the cluch or tranny. It had to be the fuel system. It was almost like it had a huge deadspot and then it would just stall out and then throttle up hard until I backed off the gas and then it smoothed right out. It would also do this at lower speeds if I was climbing a hill. On hills I would have to slow down to 60.
I am curious to see if you guys think this may be due to the rediculously hot fuel I am trying to cram down its throat or if you think I may have something else going on.
By the way, in addition to the fuel line mod I am also doing a complete tune up and adjusting the valves. I have neglected both for a little while.
As always, thanks for the help.

The bucking could be caused by a bad plug wire.

Glad to hear a good radiator is keeping the engine cool.

The carburetor heat shield can have holes that match the carb gasket and you can sandwich the plate between the thick bottom gasket and a thinner top gasket.

I would also check the plugs wires and the distributor cap.

I'd check fuel delivery too. See how much the fuel pump delivers in 15 seconds. It could be you have a plugged up strainer in the tank, weak fuel pump, or plugged fuel filter. If you have a metal T fitting you can even check for vacuum in the fuel line between the tank and pump. That will show you if there is a restriction in the line.

Did you drain the old gas out before you stored it? or add stabil to it. I didnt on my truck and it was varnished up and stank. I was lucky and fresh gas and 2 fuel filters took care of it, after draining the tank.

Short update....
I have been having a hell of a time locating and gathering up all of the parts for the fuel line mod. I should be picking up the last of the parts tonight as just about everything had to be ordered in. Since I have to take another 300 mile trip today, before I'll have time to replace the fuel line, I asked about some interim fixes just to get me down the road. While looking around under the hood I noticed that the rubber fuel line from the tanks hard line to the fuel pump was a little short and slightly crimped. So I changed that out. Not sure if that had any real effect. The next part is the cool part... I ran into one of those "old school guys" at an Advanced Auto while I was considering using header wrap to try and insulate that fuel line. I was complaining about the price when he suggested I go to a grocery store and by a roll of reynold's aluminum foil for $1.19 and just wrap up with the shiny side out and mash it to the line. The theory here is that the aluminum will reflect and dispurse much of the heat and should keep the flowing fuel cool. It's working great! I ran that thing at 80 mph without skipping a beat, shut it off and started it right back up.

I would never recommend this as a permanent fix but it can help get someone out of a tight spot. And if anyone is sceptical about this fuel line mod or if it will cure their ills, I think this is a good, cheap way to check if fuel line temp is causing any issues. I'll write later and tell you how the fule line mod works out. I am pretty excited about getting it installed.

Thanks again for all of the help

Fuel line mod installed. Took all of ten minutes to do and the truck runs great!! I am not sure how this truck ran for thirty years with the stock setup but I guess that doesn't matter. Thanks for making it easy by supplying all of the part numbers and the excellent description of how to set it up.
