I have a 1965 TR Powered +4
So I recently replaced my radiator with a high capacity aluminum unit, and also installed the plastic 6 blade puller fan from Morgan Spares.
The car is cooling beautifully now...175 degrees or lower at the block - even in 90 degree Houston heat!
Unfortunately I'm having bad vapor lock issues since replacing the radiator. If the car sits for 5 minutes after a 10 minute drive, it won't really start unless I open the hood and let things cool for 5 10 minutes. I assume the problem in that engine bay temps are now increased by all the heat dissipation by the new radiator and fan. The fact that the fuel line runs right in front of the thermostat housing certainly doesn't help!
I wrapped the metal fuel line in a thicker, split rubber fuel line...no change.
I assume the problem is at the carbs, when I spray the Strombergs with water to cool them, the car starts right up.
I'm wondering what the best solution to fix this problem is:
1) Buy a Stromberg heat shield? (I doubt this would work, since the problem is hot air from the radiator, not excess heat from the headers...)
2) Wrap the Headers? (might help cool the carbs - but see #1 above..)
3) Install a Facet electric Fuel Pump?
Any advice appreciated...
