[QUOTE="MG0h3, post: 16641080, member: 164690"] I’ve never had it happen on a fuel injected car but have on my old Jeep after it sat out in the 105* sun. Basically the fuel vaporizes and the pumps can push the fuel. Typically going to vaporize in the fuel bowls (carb) or rails (FI). Fuel leaking is prob the filler neck seal at the tank. Got damaged due to age and then moving it when you dropped the tank. MalcolmV8 did extensive testing and the pumps don’t heat the fuel. It’s from recirculating through the hot rails. I’d say it’s 50/50 on people running Hobbs or both pumps full time and no difference. I doubt both pumps are failing though. Slim chance. One pump is more than enough to keep your pressure cruising around. My second pump doesn’t come on until 5psi and I’m on E. Sent from my iPhone using svtperformance.com [/QUOTE]
