What happens here

With the fuel pressure drop confirmed, the team discusses the solution. The primary plan is to install a 'hot wire kit' which involves running a heavier gauge wire directly from the alternator to the fuel pump, utilizing a relay. This will ensure the pump receives the full, consistent voltage it needs to maintain adequate fuel pressure at high RPMs, bypassing the limitations of the existing wiring harness. They also consider replacing the fuel pump itself as a precautionary measure, especially if it was damaged by previous fuel starvation. The conversation emphasizes that this upgrade is necessary regardless of the transmission swap.

Goal: Outline the solution to the fuel delivery problem.

it's cranking the the voltage up to it just like a a booster pump would so with this thing if you're you know not getting the voltage back there then that's that's probably what we got going on yeah a little wire i don't know why i never thought of that if that's how the escalade was and that's how this thing probably should be too yeah i feel like we got to do that before taking the transmission out because then we don't learn anything yeah you don't know the full potential right now i mean you know it'll make it leans out so quick you can you can just watch the i mean it just clicks it off quickly i mean i shut it right there yeah i shut it down you know i didn't it didn't go as high as it did before but um and you can see their fuels i mean
