The first few time the car stopped, I reached back and opened the fuel cap. I could not hear any "whooshing".
I have a ceramic-coated 4-2-1 header from Spitbits with no thermal separation near the carb with a new Pertronix electronic ignition module and coil. I'll try the cheapest fix (new fuel filters) and work my way upwards in price. I suspect that there is blockage in the fuel system to the point that when I'm below a third of a tank, there isn't enough "head" to get the fuel all the way to the pump. I neglected to mention that this started a couple of years ago after the car just sat for a 5 month rebuild of the front suspension. I suspect now that the gas tank got rusty from the non-use of the car, and has been getting more and rustier since then. The next step would be to coat the tank with the kit from Eastwood. After that, a new tank from Spitbits. Thanks, all. Have a great British Car Week! -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Greg Rowe Sent: Sunday, May 28, 2006 9:44 PM To: [email protected] Subject: Re: Starving for Fuel? The gas tank vent that runs to the charcoal canisters might be blocked. If so, as the fuel is pumped out, it creates a partial vacuum in the tank which the fuel pump is eventually unable to overcome. This is easily tested by opening your gas cap when the car dies. If you have a WHOOSH! of inrushing air, that's your problem. Best!
