What Happens If You Turbo a 5.3L Yukon With No Other Mods? PART 2: Fuel Injector Upgrade! (RIP 4L60)

What happens here

The project involves unboxing and reviewing the new fuel system components. These include: Deatschwerks 1500cc fuel injectors (8 units), a DW400 pump module (a factory-style sender unit with an upgraded pump), and various fittings and tools needed for installation, such as an adjustable AN wrench. The pump module is designed for 2004 and newer gas tanks, requiring a larger sending unit hole. The team notes the instructions available on the Deatschwerks website for installation.

Goal: Gather and understand all necessary parts for the fuel system upgrade.

Tools and materials

  • Adjustable AN Wrench — Tightening AN fittings
  • Box Cutter — Opening packages
  • DW400 Pump Module Deatschwerks — Upgraded fuel pump and sender unit

we got the unboxing of the fuel system you just told me you didn't know i had these sitting here and we could have just popped the injectors in and probably made it go a little bit farther last night just to see what it does this is the whole fuel system from deets works that they shipped to a random doctor's office in forest hill actually they didn't ship it to a random doctor's office fedex rerouted it to a random doctor's office and i don't know how that happened but i had to go there and pick it up because they opened it and called me which was funny but there's all kinds of cool stuff in here how do you feel about each works i like their stuff i only use them or id really mostly if i get to pick that's who i would pick so because i know different injectors have different characteristics like factory dw has good characteristics on their injectors they spend a lot of time on getting them all flowed and boxed together right what we got here we got injectors 1500 pound injectors which tanner was like oh we could just pop those in and we could have turned it up a little bit more what size is that i said 1500 and then he's like do you think we can make these work i i'm pretty confident we can get him to trim on 93 but it's gonna be it's gonna be fun so we will see just because they're so big and if we do get them to trim just fine on 93 there's gonna be a lot of haters a lot yeah the logic was uh we do the injectors one time never had the mess of them again so everything in this fuel system except for the pump will pretty much carry this thing well past 1000 horsepower yes but you know that's something that we can upgrade as we go here's the pump module this is cool i've never actually seen one of these oh dang so it's pretty much just like a factory style sending that with a turn that they build themselves so it's like correct yep like they have everything here the entire fuel system everything we need is in here they sell things as kits like this another good thing about them is on their website they have a step-by-step instruction like it's you don't have to be like a full-blown shop to buy this and put it in like they have step-by-step instructions on their website i remember when i did the i put a walbro 450 in the escalade years ago when i was like 19 to pull this out and everything really was not that difficult um but it was kind of confusing because i'd like make my own hole and the bucket wasn't right i had to modify it i didn't know what i was…
