Max fuel PSI? What is the max fuel PSI for this carb?

Max fuel PSI? What is the max fuel PSI for this carb?

Answers

Speed Demon carburetors require the same fuel pressure limits as the Holley or Edelbrock. If you have a fuel pump that has 6-8 psi pre set then you will be fine but if you have a high pressure and high volume pump over that then you will need to run a regulator to avoid pushing fuel past the needle and seat causing flooding of the engine. Regulator number 42712803 or 91012803 are a couple of examples of regulators and an inline pressure gauge such as number 91011581 or 1822175 can be used to dial in the proper fuel pressure.
