What's wrong with it?...Leaking?

carboy2011 · September 14, 2012

if its a leak then i have had it done in the past and its a tricky process and a bit dangerous too due to the fumes in the tank even when empty,you need to rinse it several times before you can bring the welding torch near it many garages are wary of doing it though

but if ur refering to repairing the float in the tank then thats easy to replace

'carboy2011',

Your method is correct, What I used to do to many Petrol tanks is clean the leaking point very well.

Then keep a brass sheet cut to double the size of leaking area 20 gauge and solder with lead This method do not wand very high heat or the flame

If bottom of the thank is very badly gone corroded with so many Petrol leaking places, then have to cut open the entire bottom of the tank.

Make 20 gauge new metal sheet bend on the ends. To fit the tank has to use Oxy acetylene flame. Do brass or good tinker can do normal welding.

Remove and close the gauge unit and the Petrol filling side also before start welding. To avoid water leaking out.

Weld the cut opened tank entire bottom. Before that fill about 2 inches water below the welding area.

After all that can do a pressure test to verify there are any leaks. When water is in the tank.

Bottom by turning the welded tank area. To the top normal fuel filling position.

After everything rinse the tank with little petrol to get rid of water.

This job has to be done by an experienced Tinker.

Ir it is a tiny hole, You may use BELZONA or ARALDITE (2 pack epoxy) to seal insted of welding.

Whats the vehicle?

If the damage to the tank is severe, why not consider replacing the tank?

U can get them from delkanda or panchikawatta

If cap lid is leaking, check the cap lid seal, when you close the lid there should not be loose play the tank and the cap lid. If the lid is loose then change to a new lid or change the lid seal. If the lid is other than metal check there is a crack on the body of the lid.

it's really hard to explain the exact issue.

i'm referring the open to floater and fuel pump.

lid to be mounted to tank with bolts.

lid seal is there.

but due to some reason (can not understand how this happened) surface where we are to fix the lid is not even.

hence though we fully tighten the lid, there is a gap between tank and lid at some places.

since the nuts seems to be welded to tank, this seems to be a bit advance tinkering work to repair the surface.

Kit,

For what reason you want to do tinkering and welding on that point, is that point is corroded.

Do check your packing what is on the the lid. May be the lid packing is too thin or due to old packing it may be hard and leaking from that .

If it is so use thicker new packing do nit use rubber rubber will warp or melt for Petrol. You can buy thick cork sheet from a motor spare part shop use.
