Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

Yes, cut the hose down the middle and pop it over your fuel line in hot areas. Like pipe insulation.

Ported from jalopyjournal:

Vapor lock doesn't happen between the pump and the carb, it happens between the tank and the pump. The suction of the pump lowers the pressure in the line and a t the same time lowers the evaporation point of the fuel. So if you have a restriction or a hot spot in the line the fuel evaporates before it gets to the pump. The pump won't pump enough vapors to run the engine.
So check for areas where the line runs close to the exhaust system or lays downstream of heat from the exhaust. Best way: drive it till it falters, crawl underneath and run your hand down the fuel line feeling for hot spots. They'll be easy to find.
Check for restrictions: smashed lines, plugged lines, plugged pickup filters and the most insidious of them all the deteriorated rubber line on top of the tank.
Get the flow specs for your car and check the fuel pump output cold. If it's not to spec see above before you replace the pump. While a new pump may cure the problem it is likely due to other causes and will recur if the pump you have is fairly new and will pump to spec from a container that eliminates the present fuel system. Disable the ignition. Take your emergency fuel supply can and a short piece of the proper size hose and hook to the inlet side of the pump. Another piece of hose on outlet into a graduated container. Crank for specified time and measure output
If the pump fails both tests replace it. If not, the problem is one of the above.
