PWM fuel pump

Hi Tony

I am very interested in your comment re: PWM fuel pump. Is this a fuel pump that has improved performance? I am guessing you have removed your original carburettor (Edelbrock)?

Appreciate your insights.

Hi Mike
No need to replace the pump, the box of tricks from VaporWorks (owned by Aeromotive), from what I understand, either has a sensor in the fuel line or uses the vacuum off the carb to sense the amount of fuel required and then controls the speed of the pump to supply the correct amount of fuel to the existing carb. The PWM bit is how it controls your existing pump. So, as the pump isn’t running flat out all the time it’s much quieter. Have a look at the website.
Hope that makes sense.
Tony
