fuel pressure regulators

Back in the day, low-pressure fuel delivery systems were the norm. As carburetors evolved and fuel injection came into play, fuel pressures increased and low-pressure systems became common. However, low-pressure fuel systems remain relevant because many vintage cars use Weber or Stromberg carb setups. Aftermarket low-pressure pumps and regulators are also used to replace OE parts for

Q: I’m building a fuel system for my 1969 Chevelle. I plan on running an electric fuel pump that puts out a maximum pressure of 14 psi. What type of fuel pressure regulator should I use? A: You can use a bypass (return) on a non-return style fuel pressure regulator. A bypass regulator sends unused fuel back
