Review on ๐ฅ Holley 12-803 Reg, Fuel Pressure 4.5-9 Psi, Shiny: The Ultimate Fuel Pressure Regulator for High-Performance Engines by David Flores
Fixed tripping when turning into lanes
Edelbrock 4-barrel carburetor coughed and hissed when turning into lanes. It has been said on several forums that most fuel pumps, especially at idle, put too much pressure on the Edelbrock, causing the fuel level to rise too high and thereby running too rich. This fixed that problem. And as a bonus, I find the engine runs smoother even at cruising speed.
