Fuel Pump Replacement
The new pump that I fitted in 2020 (a reproduction 40083-style pump) started leaking. In December 2023, SR Performance replaced the pump with another reproduction 40083-style pump. In April 2024 this pump failed and was replaced again. It was difficult to find a suitable pump, the Holley carb on the L-79 wants only around 7 pounds of fuel pressure, most of the mechanical pumps available deliver at least 14lbs. SR Performance fitted and tested three pumps before they found one that had the correct fuel pressure.
