Machine Builders Network+ Forums Thread Like Summary - Diesel tank repair ideas???

Need ideas on fixin a couple of pin holes in my diesel tank on the F-350. Got the tank pumped out and off.
Would love to braze it BUT that probably would turn ugly! lol! -- Soldering, same deal, --- heat might set it off with fumes in it.
I know diesel takes a lot more heat to burn but even soldering needs a lot of heat.
Neighbor says to slap JB on it and go! --- dont think JB is going to hold diesel fuel in!
Cant find a used tank in decent shape,---they are all MUCH worse than mine! lol!

Sonny you're NOT gonna 'set off' the fuel tank..you really only have that problem with gasoline tanks. The JB repair won't last,you'll be pullin it out again..I'd wash it out with water(and you really dont even have to do that) and then run shield gas from a MIG welder into it for 10mins or so, even that is really unneccessary...Clean off any exterior coating or paint then MIG it or braze the holes up, then rinse out with 1202 (Diesel)-use that same rinse diesel to check the pinholes for leaking..you'll do fine. Ive welded and cut on diesel fuel tanks for 20 yrs without ever one 'going off'..Ive even seen welding done on gas tanks in cars with gas still in them..no big blast,no fire either.

Welding up gas tanks

heat it and braze it up Sonny..I'll expect it to be repaired and back in the truck and running by 3pm today..finish that coffee and get that torch warmed up

Hollywood has so many people scared of gas tank explosions..too many movies..
at least she's workin for ya Sonny..I always put a strip of roofing felt inbetween the tank and the mount strap,it cuts out the friction wear of the strap and gives it some cushion.It looks like thats what got you so may holes in yer tank...Anyway if you get tired of workin on that 7.3L Ive got a brand new,in the crate 6V53T Detroit for sale if you wanna swop in some fun to that truck

Its a 1997 F-350 7.3 diesel automatic (that is junk) and a 10' flatbed.
Got the tank brazed yesterday, ---- I'm still alive,--no fires in the process. I stuck the air hose in there and turned it on half way to blow the smoke/fumes out. worked great. still had about a gallon of fuel in it that didnt come out but it didnt burn.
Hope today to put the tank back under the truck.
pix. of the mess! lol!
