Repair Diesel fuel tank

Is the tank steel or plastic?

G'day Kevin, this may sound stupid, but true..I fixed a leaking tank on my diesel Peugeot 504, many years ago...by mixing dust from a tyre rim with softened soap into
a putty, & applying to to a clean, but still leaking area. It worked perfectly & lasted
10 years plus.
No doubt you will get more realistic solutions ..but it worked...:))).
cheers....oldbaz.

pull it out ,solder a patch over the area
end of your problem !!
an get on with your life
cheers mechpete

The only way to fix a hole in the tank is silver solder 35% either drop the tank and fill it with water then empty it and solder it. Don't put a patch on it just silver solider but it has to be at least 35% silver. You can get it at ant CIG store.
Cheers Andy
PS Have done this to jerry cans as well and my main tank.

A bloke bought me an old tank out of a Toyota Stout (petrol) one day for repair that had a lot of holes in the bottom of it.
The tank was virtually a write off before I got to it.

I wire brushed it and enlarged many of the holes with a screw driver then applied panel beaters Bog to the whole area forcing it into the holes slightly so that it "keyed" into the holes.

Still going strong after 15 years.

Remember that diesel has virtually no surface tension so it wets everything it comes into contact with. Whether you solder, silver solder or use bog, it must be very clean and free of diesel before starting the repair. Also look for leaks in the surrounding metal as it may be coming from another location as well.

Cheers, Bruce.

Hi Kevin, about four years ago, while fitting camping drawers to the back of our Cruiser, he who shall not be named, drilled through the diesel fuel tank!!!!!! It was in a very hard to get at spot and he couldn't even see the hole and had to go by feel. However he managed to squeeze his hand in enough to to give it a bit of a rub with sandpaper and then he used a product called Dyna Grip Quik Steel - metal tank repair kit.

It is still sealing that hole to this day!!! Mind you, we keep some of it in the tool box at all times wherever we go.

Hi 116 Hynes. You are not probably going to believe this but it works. I use to own a road house & a truckie came in with this problem. He showed me what to do.

1 purchase a packet of minties. The minties will stick to steel, aluminium or plastic but I would prefer to only apply the Minties to either steel or aluminium tanks.

You have to soften the Minties in a jug of water until they soggy & then press the soggy Minties into the crack or hole.

You not need to pull out tank unless you cannot get to the effected area.
