Affordable Flex Fuel Setup
Made a post earlier asking if I could run stock pump and BAP on a C6 LS3 with supercharger to run E85 and was pretty much told it was a no go. My question is what are some affordable flex fuel set ups out there. I know the dsx flex fuel kit is the way to go. But what’s a good pump for a good price. Is there a setup I can run that works pretty well for around $1000 out the door include pump and flex fuel kit.

East Coast Supercharging has external setups for 1200-1500 depending on what you go with. Call and talk to Doug Ring, he'll get you set up.

to give you an example of my setup. stock fuel pump, boost a pump, ECS external fuel system, ID1000 injectors and Alky Control. I am using the methanol to supplement my fuel system because my injector duty cycle was getting too high. I really need to change my setup to have a boost referenced fuel pressure regulator. To do that, you have to drop your tanks and cap off the fuel pressure regulators in the tanks. If I do that, I will definitely add more pump while the tanks are out.
Your setup simply will not move enough fuel and maintain pressure you need running e85 with boost.

They make both the flex fuel sensor kit and an aux pump solution for C6 Corvettes. Add in injectors, and any decent tuner can install and tune it for you.

The heart of the system is a DSX Tuning proprietary PnP controller that plugs into the MAP sensor. There's no need to tap vacuum lines or install a Hobbs switch as the DSX Tuning controller utilizes the electrical signal from the MAP to trigger the pump. The controller is incorporated into an easy to install harness with minimal connections to ensure the end user doesn't have to do any wiring. The pump is activated at 8psi (157kPa) and shuts off when falling below 6psi (144kPa).
