It may seem as if this project has come to a halt but it is continuing in fits and starts. Lots of little things done, not worth mentioning, but they take time. Some travel has slowed things as well. Enough excuses.
I did get some plumbing done on the radiator vent system and on the fuel system. There is a small line from the top of the radiator back to an aluminum tank that has a pressure cap and a drain line into the water pump inlet line. An overflow line is routed to a small aluminum catch tank. This way any air bubbles in the coolant flow will not air lock the radiator, they will be vented to the tank instead. This also allows the system to be fully filled with coolant. I used 1/4" Nylo-Seal tubing and brass Poly-Flo fittings. I also connected my oil pressure line from the block to the gauge with the same type of tubing and fittings. I've ordered some fire sleeve to cover the exposed oil line.
The fuel lines to the electric fuel pump, filters, and carburetor are done. Setting the float level was a comedy of errors. The first time I tried pressurizing the system I saw leaks around the sight plugs and float level adjusting screws. I didn't have any new Holley washers so I scrounged around and found a few Teflon washers that fit. The next time I pressurized the fuel line, gas shot up out of the bowl vent tubes! Arrgghh... obviously the float level was WAY too high. I lowered the level way down but even the end point was still too high. It eventually dawned on me that the problem was the thickness of the Teflon washer under the float level adjustment screw- it was much thicker than the Holley washer. This did not allow the adjustment to lower the float all the way down. A trip to town- Don's Hot Rod Shop- produced the proper Holley washers and I was able to adjust the float to its approximate level. Lesson learned.
