Same top will be Tig welded back in place.

Opened and looking ok. Just some dent work to do.

Thanks for showing Craig. Never seen inside one of these. It looks spotless, like it has just been galvanised. Have fun putting it back together.

Nice work Craig. How does the lid come off, is it soldered so you can use a gas torch, or welded and needs cutting and grinding, or a bit of both?

Cheers,

I think they are seam welded i.e. similar to spot welding. Lid section has been cut out just on the edge of the welded seam joint.

I have cut a 150mm hole in mine to fit a VE Commode fuel pump into for my upcoming EFI conversion, also welded a baffle all around the fuel gauge sender unit to try and stop fuel slosh from making the needle rock and roll while driving - will see how successful it is if I ever get the time to fit it all .....

Talk about mod cons blacky. You’ve rodded yer petrol tank

I could be wrong, but I suspect that they are mild steel which is then tin plated. Once the tin is damaged (say a heavy scratch that exposes mild steel), they set up their own electrochemical rust cell (two dissimilar metals). The bottom of the tank is usually dry (no electrolyte, little rust), but the topside is often moist (leaking boot) and rusts out first.

Yes Harv I suspected similar. I'm reading that the material that may have been used is called Terne metal. This was a common fuel tank material with lead content. I was always worried about disturbing the corrosion protection (what ever it ruined out to be) and think I will have to do some acid washing after the lid is welded back on the seal the tank internally with POR or something similar. I'm wondering if I could get it re-dipped (galvanised) after I've done the work as an alternate option.

I like a rocking needle. Once it stops I know there's bugger all in the tank and I'll get 25km before it snuffs out.

Hahaha, who needs a low fuel warning light?

[rosco]

Me too, Craig - when my needle stops bouncing off the peg, my thoughts go to things like rain and which way to start walking... ran out twice in my life with the old bus - first time was in company of another car with outboard fuel in its boot.... Corowa (servo bloke pumped fuel up into the glass bowl above the bowser...... at the first town we arrived at, no number display - just a hand pump on the side of the metal box and the bowl on top with a hose running down from it, release was controlled by a valve on the hose -1973). Second time, between Lakes and Bairnsdale - went into Bairnsdale to do shopping and get money out of the bank.... fuel was cheaper at Lakes, my calculations were out by 4 miles... I wrongly thought it was 18 miles to Bairnsdale, it was 22!.... I walked the 4 miles, and - as it does.... it started to rain. Nice bloke from the servo drove me back.... (earned himself a cold six-pack for his generosity).
My original sender unit blew up.... I put together a huge thread on it somewhere in here. You may recall the "Bogon Moth" saga.... took ages to get the rotted fuselage of the infiltrator out... wings and legs desolved in fuel over time - but the body didn't.
You might consider fitting a fuel filter of some sort to the outlet pick-up.... not plastic.... something akin to the material in the fuel pump bowl. I doubt that it would clog up in service as the rocking motion of fuel should keep it washed.... something to think about.
For some time, 711 store fuel was coming in from Singapore unfiltered. Bursons told me at the time they were selling up to 10 "in tank" fuel pumps a week.....
Another time, (Charlestown, Newcastle) I was towing the little caravan to Taree to stay with relatives... I put $3.96 worth of standard fuel into to fill (fuel then was around 0.40 a litre).... we just made it out of town and the old bus started to run rough, eventually refusing to run.... pulled over to the side of the road and did the "usuals".... lifted the air cleaner off and pumped the carby arm... saw "white" emusified fuel coming out of the jet.... water. Walked to a phone box and phoned the servo up "can you get it back using the choke, we've just found out the young bloke left the cover off the fuel tank when he dipped the tank". I was told to leave the car stationary for about 30 minutes then undo the drain plug under the tank until the water came out and solid fuel started to drain. It sort of worked - but it still ran rough and spluttered a lot. Got it back to the servo - they spent a good hour cleaning out the lines and carby... but it occasionally played up for a few weeks......
The bloke told me he couldn't work out the numbers when he signed on.... the tank was some 120 litres fuller than that which the young bloke recorded at the end of his shift...... it rained very heavily that night, the stupid driveway of that servo had a channel which ran down and across the filling/dipping cover of the standard fuel underground tank...... I look at these things now, more so when in the 200... you simply can't mess around with water and a diesel engine - a replacement for our truck is $45k.......

Ok, been missing for a while - you must really hate it when I finally surface.... you must know you are in for a "biggie".

frats,
Rosco

All good Rosco. When I see a post coming from you, I just go and make a cuppa and make sure I’ve got nothing to do for the next hour or two before I start reading it. Thanks for the tale.

One more oil leak to master after this solution.
