Preventing vapor lock
I can drive the car for about 20 minutes with about 10 gallons in the car and then she sputters then dies. Let her sit for 10 minutes and she fires right up. Vapor lock. With 5 gallons it takes about 5 minutes and the car dies. Here's the setup: 440 iron block with EFI, jet hot coated headers, Aeromotive A1000 EXTERIOR mounted pump lower than the tank. -10 feed, -8 return, 2 filters, pressure regulator set at 59psi. All lines insulated starting at the header collectors. After 10 minutes of idling, my headers are close to 600 degrees, and the sending line, return line and fuel rails are 250 degrees. Fuel boils at 205 degrees. I'm ordering some header shielding and maybe some fuel rail shielding. Last resort is ordering an in tank pump. I know most of ya'll are running aluminum blocks but do ya'll still have a ton of heat shielding around your motor? And are fuel coolers worth the money? Thanks.
