Rocket Man's 2008 Bagged CC Silverado Build AKA "THE MACHINE"

It does look like a demon with the quad demon eyes.

I’ve been smelling gas for awhile now so yesterday I used brake cleaner and cleaned the fuel cell. Today I took a look and it seems like it’s seeping at a weld at the bottom rear corner. I didn’t get a picture while I had it up in the air. So…I think I’ll try to find someone who will grind the corner and reweld it. I have looked into having a 20-25 gallon tank made (this ones 15 and I have extra room) but I’d be looking at $600+ and probably 6-8 weeks lead time. I just want to stop the leak for now.

The bad part is that you will have to remove it and fill it with water a few times before anyone will even THINK about welding it.

Ehh. It takes about 10 minutes to remove it. It’s only got about 5 gallons of gas in it and it has a drain. After the gas is out it takes (4) 13 mm bolts and it’s out. Then I’ll pull the fuel pump and the remaining gas will evaporate quickly with a huge hole in the top where the pump was and the drain removed from the bottom. I’ll give it a couple days though.

I did my grocery shopping this morning and when I came out of the store there was a silver dollar size puddle of gas under the truck so it was time to fix it. It’s kind of scary thinking all it would take is a spark and this thing would go boom.

I pulled the fuel cell, drained it and removed the pump. I can see a hairline crack right through the welds in the area it’s leaking. It looks obvious to me that’s where it’s coming through. I don’t know much about welding but that seems like a weird way for a crack to show up, straight down the middle of so many puddles. Maybe someone else more experienced in welding can shine a light on it. I’d like to know if this is something I should be worried about with the rest of the welding or what? Anyway I’ll find someone to reweld this seam this week hopefully.

Actually I just thought of how that crack might have happened. The fuel cell is even with the bottom of the rear frame right there where that crack is. I always put a board on top of my floor jack which partially spans the bottom of the fuel cell right there so I’m thinking that when I jack the rear of the truck up, that’s putting slight pressure upwards on that area of the cell and since it’s mounted by the ears on the tabs it’s solid and has no give so it pushes slightly up on the bottom of the cell but the back side doesn’t move so it’s cracked it. I will have to rethink either the mount of the cell- get it to set up higher- or make something to jack the truck up with that won’t touch the cell.

Pretty but weak weld. During certification, your weld must be stronger than the material you're welding. @randeez intake did the same thing

dont bring me into this

I blame you for this weld crap.
