Lingenfelter Trailblazer SS High Flow In-Tank Fuel Pump

The Lingenfelter Trailblazer SS / SSR Fuel pump upgrade uses the GSS341 pump TI / Walbro fuel pump. This pump flows roughly 50 gph at 60 psi at 12 Vdc, 60 gph at 13.5 Vdc and 75 gph at 16 Vdc. Some of this flow is used to run the jet pump or venturi pump that fills the fuel pump bucket or canister. Without voltage boosting, this should be enough fuel flow to support roughly 650 to 700 hp naturally aspirated and 550 to 650 hp in turbocharged/supercharged applications. For boosted applications above 650 hp and naturally aspirated applications above 700 hp, we recommend voltage boosting the pump to 16 or 17 volts with a Boost-A-Pump. At high fuel flow rates it may be possible to empty the module or bucket faster than the jet pump can fill the module so make sure you do not run low fuel levels when running at high power levels.
