Fuel Boil
I have been experiencing fuel boil problems on my 79 F150 with an Edelbrock 600 for a long time now.
I recently installed a phelonic 1 inch Spacer and it has been working fairly well. I have no fuel boil on a mid 80 degree day but when its around 95 outside and humid I am still gettin fuel boil.
Can I jump up to a 2 inch spacer and that help more? Or is there something else I can do to lower the heat to the carb? Thanks.

Yes you can...and it would help...but IMo it would only be a bandaid. I live here in NC and have experienced well past 100* temps and have never experienced 'fuel boil'...but have heard of it. Typically something is wrong or doesn't have sufficient cooling. Most of the time it comes from poor routing of the fuel line. So if you have any slack laying on the intake or close to an exhaust manifold or mixed in with a heater hose, you may want to sort that out.

I have fuel boil problems with all of my trucks except the one that has the factory motorcraft on it.
I have the fuel line as far away from any heat sources as possible. Its not dangleing down close to the intake either. The truck will run 190 degrees all day in and out of traffic but when you shut it down it builds heat to about 215. I know the engine will build heat when its first turned off but what can I do to make it not build so much?
A buddy of mine has the same problem with his 79 F250, it runs 190 degrees but when first turned off it almost builds to over 220. Then thats when the fuel boil happens I suspect.
I also think west Kentucky has a different heat than other states. Its humid nasty heat. At 90 degrees and above its almost a death wish to go outside and work on something around here.
