Replace DSX pump or go port injection?
My DSX pump took a crap and it is $900 for a new one. I am running 861 WHP with a Maggie 2650, cam, intake, headers, and pulley.
What is everyone's thoughts on replacing the pump vs adding port injection instread? The pump lasted only about 4K mi and 4 track days and is not under warranty. |

Low side will still need to be addressed to feed the port injection.

Have you considered the "in tank" Katech solution?

Check out our dual in-tank fuel pump module.
It retains factory bucket functionality and will easily support your power level. https://katechengines.com/i-30498248...mp-module.html |

Thank you. I will look into the Katech as I also wanted to go e85 in the future anyway. I already have the Katech oil pump since I cammed it and it is a 2017 build. Tacked it with no issues. I appreciate everyone's help!

I would use the KISS method and simply replace the Aux pump.
