What happens here

After fabricating the custom exhaust system, the host installs new, custom-made braided stainless steel fuel lines, replacing the old ones that were leaking and the pinched wire for the fuel sending unit. The fuel tank is then reinstalled and the system is pressurized to check for any leaks, ensuring safety and proper function. The completed exhaust system is temporarily mounted under the car using ratchet straps, allowing the engine to be started and the new exhaust sound to be heard for the first time. The host notes that the exhaust will require final welding and proper hanging after this initial test.

Goal: Complete fuel system repairs, install the custom exhaust, and perform an initial engine start.

Tools and materials

  • Battery Terminal Wrench — Connecting the car's battery

  • Fuel Pressure Gauge — Monitoring fuel pressure during testing
  • Fuel Tank — The reinstalled fuel tank after inspection and pump placement
  • New Fuel Lines — Replacing old, leaking fuel lines and ensuring reliable fuel delivery
  • Ratchet Straps — Temporarily holding the exhaust system in place for testing
  • Fuel Pump — Replacing the old fuel pump during fuel tank inspection

oh also i don't know if you noticed uh we did a little bit more organization in the shop i stuck some of those up there old world of wheels things when i had the escalade in there in pittsburgh way back in the day and you know i made this quick little hose rack extension cord rack thing just a two by four with some pieces of metal i bent on the back and screwed under the wood and then that way i didn't have to put these hooks into here and this could also be moved if i wanted to taking bits and pieces out of the shop one annoyance at a time so now i'm gonna go get some pipes to fit in there uh there's a bunch of scrap outside i'm gonna see if i can find some short little pieces cut them and see if uh maybe i can make something work here well kind of got carried away in a sense but boom marking everything out on the floor worked perfectly got it exactly where i want it everything is good the headers don't come out of the exact same space so i had to reuse some nasty old pipe from the old exhaust to get it to reach but it's connected it's on there i got held up with the ratchet straps for now um i gotta put the new fuel lines in ones that we got made put the gas tank back in and we can fire this thing up and at least hear what it sounds like i still gotta make mouse for it but i'm gonna do that after because the exhaust is just kind of it's not clamped or welded anywhere yet it's just tacked in there to get the angle but i want to hear it before i do anything else because that's what i want to do and if you don't agree with that you can suck it i don't want to hear it make sounds do you want to hear it make sounds yes what are you doing right now which shirts my favorite shirt yeah these are pretty sweet do you guys think we should use this gmc looking logo on other stuff it's time to turn it on are you ready and find out how loud it's gonna be and what we're gonna have to deal with when we drive this thing around yeah hold up i'm gonna hook the battery back up something i need to fix when this thing got wired if the battery is hooked up the ecu has power all the time i didn't wire the fuse box one of my friends did while i was working on something else so i don't know how that happened yeah i hope to figure that out and we got to open the door because it'll get incredibly stinky in here very quickly it's not very big in here we'll see if it has fuel pressure can you go point the camera on the pressure gauge on the regulator right up here see if there's any…
