I attempted to change the fuel filter on my '81, but I couldn't get fuel line fittings loose. I used a fuel line (slotted box) wrench and an open end wrench to hold the large brass reducer that threads into the carb.
I managed to loosened the large diameter reducer from the carb, but I couldn't loosen the fuel line fitting that screws into it. I couldn't remove the fuel line without twisting the metal fuel line.
Liquid Wrench didn't help. The fuel line fitting was so tight I eventually rounded the hex. Any suggestions on how I might separate the two parts without twisting the fuel line?
I could cut the fuel line and use a short piece of hose to connect to the carb. However, I would need a reducer--one with a threaded brass fitting to screw into the carb and a 3/8" hose barb to connect the fuel line hose. Does anyone make such a product?
I know what you mean. Those fittings are put on metal-to-metal and often freeze tight. On my old Holley setup, I ended up removing the steel fuel line down to the pump and replacing with a hose and clear filter. (One of the main reasons I did it was to reduce the transfer of hear from the engine to the fuel and carb). I can't remember where I got a replacement fitting but I would think you could get the parts from a local speed shop or Jegs or Summit.
I searched the web and couldn't find a reducer. I ordered a new fuel line from Eckler's. I'm simply going to cut the old fuel line, remove the large reducer, stick the thing in a vise and then remove the old fuel line fitting. All this work simply to change a fuel filter.

I'm not quite able to picture why you think you need a reducer. My line was the same way ... fused tight. So I just cut the metal line leaving a ~1" stub of fuel line coming out of the big carb fitting. Then I just patched in rubber fuel line at the cut. It's held for 2 years that way just fine.
I pulled so hard I almost saw god. At one point, I thought about laying on the car's roof to get more leverage on the wrenches. A cooler head prevailed. I closed the hood and walked away. At this point, I'm going to cut the old line and install a new one.
