What fuel pump for flex fuel Yukon?

[screamin86]

I've been havin issues for some time now (2yrs or so) with my Yukon. It not wanting to cold start below 1/3-1/2 tank of gas. You can hear the pump not picking up fuel also. I'm to the point where it bothers me enough to finally fix it but I'd like to swp in a new/better pump while I'm in there. Right now I'm just bolt ons but plan on a 6l swap some day. I emailed racetronix and they said they do not carry anything to work for my flex fuel setup. What ever I do I'd like a nice plug and play setup not something I have to hack together if possible but don't wanna break the bank doing it either. Lol right now I've got 106k on the clock and it's a 2003 if that matters have no other issues other than this.

The ACDelco part on rock auto is MU1379 and has it listed for 236.89. There are other brands that are cheaper as well. I think you can find some good deals on racetronix ones but not sure if they are flex fuel compatible.

Yeah wouldn't mind a racetronix setup with hot wire kit I put one of those on my z28 and it's a nice setup but like I said they told me that they do not offer anything for the flex fuel trucks. Mine has typical bolt ons and tune but not sure what is or if anything is much different in the time for the flex fuel other than the larger injectors.

Haha, sorry about that, I didnt read the entire post. Have you tried contacting Bosch or Walbro? Is there a way to remove the flex fuel stuff from the computer? I thought it was possible.

No clue that might be something I call Allen about.

yes flex-fuel can be tuned out, and just simply unplug the sensor
