[T3] Mechanical Fuel Pump Vapor Lock

[Adam Douglass]

Max,

Thanks for the offer. I am going to pass because of the complexity of the install with a regulator and the size of the pump.

If I go with a Mr. Gasket 42S, they are really small and self-regulating. As far as the inertia switch, I can put it on the firewall right by the fuel pump relay because of the fact that I will be tying into the original wiring that is hanging down by the front beam.

Adam, I had exactly this problem both with 32 PDSITs and also with the 
Weber DCNFs. I put on a Carter rotary pump and never looked back.

I would not hesitate to do so again, if I were to ever switch back to 
carbs. It was an effective and simple solution. I used a Holly pressure 
regulator.

In fact, I still have that pump. You are welcome to it. You may get 
a kick out of my mounting solution. ;-)

I have read that type 3 cars are
prone to fuel pump vapor lock on hot restart. My car does
this. It will start fine when hot, but once the carbs run
out of fuel it will sputter and choke till the fuel pump
clears itself of the vapor and pumps fuel. 

My thoughts were to remove the mechanical pump and go
electric. I was thinking of putting in a low pressure fuel
pump this weekend. Are there any other solutions?
