Default Re: Fuel system

Interesting comments. For years I ran just the cheap Holly 110 pump on a low 11 second Qjet stocker. I recently decided to throw a Magnafuel 300 pump in it. I left in the Aeromotive regulator and started to have a problem the odd time with the carb overflowing when turning the pump on. Good thing about having a data recorder is it allows you to sometime easily figure out what’s going on. Recording what was happening when I turned on the fuel pump showed that the carb was seeing a huge hydraulic impact that the regulator could not deal with as it was downstream from it. Solution was to pulse the pump at start up.
Bigger isn’t always better
