Weird fuel problem
My z28 has a holley 650 on it. When i get about 5 gallons low on fuel it starts behaving like its outta gas.
If i stop and put gas in it, it stops sputtering and stalling.
Its not vapor lock.

Re: Weird fuel problem
What kind of fuel pump are you running?
With a carb on these cars you have to have a pusher pump, just running the mechanical pump on the engine block will cause vapor lock.

Re: Weird fuel problem
My first thought was vapor lock, so i pulled the gas cap and it still did it. Now i am thinking its a bad fuel line, intermittent pump, or terrible garbage getting stuck in the carb.

Re: Weird fuel problem
