Magnuson flex fuel

I have a 2016 FF 5.7 truck . Does anyone know if you use the OEM fuel pump / injectors for base 91 fuel? Also what’s the limit of the FF injectors and pump?

 

Move your post over here it will get you all the answers you crave.

Supercharged Wizards! Or at least a bunch that have been down that road.

Have you reached out to Magnuson?

 

I have a 2017 Flex Fuel with the Magnuson. It utilizes the factory Flex Fuel pump, there isn't a need to swap the pump unless you are going to be pushing more power than a standard Magnuson kit. The fuel injectors should be the green injectors included with the kit (they replace the stock flex fuel injectors). I think the green ones are rated at 535cc's.

I'm running a smaller pulley (2.2") from @snivilous and still using the stock flex fuel pump and green injectors, but running a custom dyno tune.

 

im looking into the 2650 kit mainly for towing I live in AZ as well so that’s good info was there any special instructions for the pump? I heard it had to be set to zero ethanol or something

 

I'm not 100% sure on the newer 2650 kit. My Magnuson is the older 1900 model. I know there is a Toyota TSB for ethanol issues on the flex fuel trucks. I don't recall anything specific during the inital install regarding that, but I did have to have my ethanol percent reset once due to the percent creeping up. I've had the blower for 3.5 years and it's been relatively solid aside from needing a coupler replaced.

If you haven't found a shop yet I highly recommend going through Jeff at Westcott Designs over by 19th Avenue and Happy Valley. They have done many installs over the years.
