So I have been working away at it.
Decided to try one thing at a time to see when I could stop making things that would lower the fuel temperature.
The first thing I did was make a custom heat shield for the carb. This went between the manifold and carb. It should help block radiant heat from coming off the manifold. I made it as large as possible, mounted my fuel regulator on top of it to block heat from getting to it too. Well I drove the car today, it was not a hot day so the test is inconclusive, but when I went to start the car after everything being heat soaked, I was surprised as it started real easy. I usually have to crank the starter for like 10 seconds. I was not expecting this much of a improvement, but I still need a really hot day to see if this will be enough of a fix.
I still plan to insulate the fuel line in a couple more places.
I probably not get the bypass regulator, as that is expensive and time consuming to install.
I though about going to a electric fan. That would give me the option of having the fan run while the engine was stopped, controlled by a thermostat of timer. The things I did not like about a electric fan were, it does not circulate air all the time, the stock fan and fan clutch are pretty hard to beat in the cooling department and the added cost.
