Here we have the highest flowing in-tank pump you can buy.  This is the pump that was used in the Dodge Hellcat cars.  It's flex fuel compatible and flows 15-20% more than the standard Walbro F90000274 flex fuel pump.  The high pressure bypass is 120 psi.  This pump does not include an installation kit, but that's also available.  We are offering free shipping on this right now, too!  F90000285
