2005 GMC 4.8 turbo no fuel
Hey fellas, I finally got the truck up and running.. I was out tuning and it seems like a hit a wall on the fuel... the truck leans out at around 4500 I've added more to the VR table and no change.. I'm looking into hooking up a fuel pressure gauge to see.. but a buddy mentioned to me that the stock 05 non flex pump is small and is more than likely unable to support the amount of fuel the engine needs.. not to mention the pump may have 200K miles on it...
stock 4.8... 15lbs E85 80lbs Dekas...
what do you experienced guys think?
If i need a bigger pump then I don't think I should bother with the OE flex fuel pump and just throw a Walbro 450 in the stock hanger... which I heard there are issues with that too???

I just realized there is a fuel section to this forum...lol...forum looks much better in a computer than a freaking phone... who let the ford guys in?? lol
I see what you say now.. that poor stock pump is no way capable of supporting that amount of fuel and corn to even make it worse...
An external FPR to go full return seems like the best setup in the long run... doesn't it?

Blue, what about the concern of the bucket not retaining enough fuel, cause I guess the actual tank isn't baffled?
