FAQ:
Q: What kind of fuel pump do I need for a LS engine?
A: Virtually any aftermarket EFI in-tank pump that can supply the 60-psi fuel-pressure requirement is suitable. Many builders suggest the Walbro 340 in-tank pump because it holds higher pressures and has proven to be very reliable for supplying LS engines.
Q: Which is the best fuel pump for a corvette?
A: Walbro GSL-392 In line fuel pump – the most common choice for factory LS swaps up to mild mod engines. 255L of flow and based off of the OEM design for corvette. Features 10mm x 1.0 inlet and outlets so be sure to grab the adapter fittings found on our website.
Q: What should the fuel pressure be on a LS engine?
A: Most LS engines operate at 58 PSI, as well the most popular EFI systems operate anywhere between 48 PSI and 58 PSI. The exception to this would be Gen V LS engines with direct injection which have a higher-pressure requirement. Always choose the proper fuel pressure regulator for your application.
Q: Can a GM fuel tank be modified with an electric pump?
A: Most GM stock sending units, such as this one, can be modified with an electric pump, but the pump needs a filter sock touching the bottom of the tank. Each Rock Valley EFI fuel tank features a dropped sump in the top of the tank. This allows for adequate floor clearance.
