S Fuel tank refurbishment

[christianyoung]

I'm nearing the end of my S rebuild and i have noticed a small weep from my fuel tank

It would appear, at some point in its life, the removable plate on the underside to access the filter has been welded on, and one of these welds has gone porous which is allowing the underside of the tank to get wet

Can anyone recommend the next step? Do i put a new tank on (stainless?) or do i get this refurbished? Can anyone recommend a place to get it refurbished (west midlands ideally)

Thanks

Before spending any money on refurbishing your old tank I think you'd be wise to check it's not rusting away in other places.
The most cost effective option in the long run might be a new stainless steel tank. Then while you're at it you could look at fitting a modern in-tank fuel pump and sender unit to replace the stupid arrangement TVR came up with.
I think Magpies has been through this loop so ask him for advice.

I would second that having refurbished my original tank and then chased leaks and weeps from the daft locking rings.

I had a leak from the bottom sealing ring on my tank. I applied an epoxy cladding with the sealing ring in place which stopped the leak. It sets rock hard and I doubt it will leak again. I had previously removed the tank for inspection and cleaning. The only area of concern was where the rubber filler hose connects to the neck of the tank.

Want to keep the 'original' look but not worry about rust and leaks? Why not fit a motorsport fuel cell in side the original?

Thanks, i think i'll just get a replacement tank

Does anyone have any they recommend or are they much of a muchness?

West Mercia Radiators in Wednesbury fixed a leaky tank for me.
Non Tvr, not that that should make any difference.
Worth a call before committing to a new tank ?

£600 tank verses 50p dab of solder, let me think about this

Hi

Although I went down the stainless steel route - ( I paid £400), I would have your original bead / sand blasted to see it's exact condition (probably £20 ish) and an expected repair cost ( or the plastic metal diy ) and then paint the outer with epoxy based coating.

If it is not good, then I can make a decision whether to stay external pump or go internal (which I did)

The tank is a simple box shape with a couple of baffles.

There are a number of companies who can clean out tanks then apply internal and external sealers which also helps with protecting against modern ethanol fuels, for example try www.fueltanks.co.uk
