Holley Sniper in tank fuel pump,only been run about 20 miles ,I went back to stock.
Fuel pressure is internally regulated to 58 psi, eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator; no separate return line is required because these modules return excess fuel right inside the tank! The Holley Sniper EFI fuel pump module was designed as a direct replacement for your factory pick-up and sending unit. There's no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard lineājust connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line.
