Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Also having it broke would have taken two sheets of 4x8 with the size of this tank.

I did not buy the steel from the guy that sheared it for me. It was cheaper for me to drive 30 mins away and buy the steel then take it to him to shear it. He asked me what I paid for the sheet and he said he cant even buy it for that cheap so thats why I only wanted to buy 1 sheet. |
Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Well today I finally was able to start messing with the tank. I got it all tacked up and test fitted it. But now the tip on my welder is warn out so I cant weld it anymore till I go pick up more tips.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Looking good Matt! Make sure you get a package of tips and an extra roll of wire for back up. :lol:

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
I have gotten the baffles and the sump put into the tank today. I am working on getting this bottom half all welded up so that I can check the bottom half for leaks.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Looks good! I like what you have done to the truck so far! Can't wait to see how the tank turns out.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
How do you plan to check for leaks?

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Ok I guess I understood my dad wrong, he said turn the tank over and trap the air in the tank and push it under water. I guess we will probably try that and if it doesnt work then I will weld the top on.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
that is better, but youll want some soapy water to spray the seams with. i doubt youll be able to totally submerge that tank. that is a lot of buoyancy.

When I check tanks and stuff, I use a pressure regulater and soapy water like Ryan mentioned. I also learned the hard way on water while testing an oil pan I modified................ |

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Before underground storage tanks for gas stations are set and buried, they are pressurized and a pressure gauge is installed. Simply let it sit overnight and see if the pressure dropped. No change means no leaks. If it's good enough for fuel in the ground, should be good enough for a truck. I would use a decent 0-10psi or similar gauge and pressurize to 10psi. Spray seams with soapy water.
Also, Ultra Low Sulfur Diesel fuel is very nasty on steel, causes it to rust pretty bad over time. Don't know why, but I would think about a spray on coating designed for fuel tanks. I'm sure there's something out there for this application. Awesome build thread too! |
Re: 85 GMC Sierra Classic 1 Ton Crew Cab
40 gallon of air at 10 psi would probably blow this damn tank up. I plan on getting a coating kit for the inside.
Thanks man! Posted via Mobile Device |
Re: 85 GMC Sierra Classic 1 Ton Crew Cab
I did get the tank all welded up yesterday, but stopped there cause I think this changing weather is starting to make me sick.
http://i167.photobucket.com/albums/u...psb4074db7.jpg Waiting on a bunch of parts to come in for the tank. Pretty sure I have everything figured out but going to wait to put the fittings in the tank after it is installed so that I can make sure I have clearance for everything. I have also decided to put the filler in the bed. I dont haul to much stuff and we bought a 16 foot trailer a couple months ago so i should be good to go with that. Plus me and sheet metal are not friends so there is no way I could move a fuel door to the back and make it look good. |
Re: 85 GMC Sierra Classic 1 Ton Crew Cab
You could move the door, just tack tack... tack it in.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Yeah the one time I did some body work cutting out pannels I messed it up bad. People may not like the filler in my bed but doest really matter to me. Works for me!

LOL that's what I was going for, glad someone got it!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
Nice work Matt. You can weld in the fuel door, just go slow. Heck, why not just get one of those billet ricer type gas doors? It'll match your no sleeve shirts and flat billed hats..........
