TR2/3/3A TR3 Fuel Shutoff leak

[dspeed]

What is the hot setup for fixing the leak on the little brass push pull valve that shuts off the petrol supply to the pump?

I'm afraid that my cork has perished after only 49 years and 10 months.

Bypass the valve....
Seriously, those things are prone to leak. They are nice to have but unnecessary. I think they stopped using them around 57 or 58.(I think around when they started the TR3A)
I've only ever seen one still hooked up, and that was because the owner was trying to keep the car 100% original (it was a 54 TR2 long door com.# TS812LO)
other than that I usually spot them sitting in the frame rail doing nothing anymore.

Cork has veins in it and this causes the leakage with the new replacement corks. So I took some black gas-resistant hose and cut it to the correct length as for the cork. Because the inside diameter of the rubber hose was loose on the spindle, I put the old cork back on and carved it down to give a good fit for ther ID of the hose. The cork is, in effect, a spacer. Then I put it all back together again and tightened it so that the rubber "balloons" out a bit, re-inserted it and as we say up here in French Canada, "voila". I haven't had a leak in over 10,000 miles.

I often thought of testing the new synthetic plastic "corks" they are now using in some wine bottles to see if it is gas-resistant. If it is, make a "cork" for yourself out of one of these. Let us know if it works.

Thanks Don -

I had not thought in those terms but can now see many possibilities. Keeping a small fleet of 50 yr old vehicles roadworthy requires some inagination. Was hoping TRF or somebody had a $2 silicon part to put this to bed.

The hot lick here is to use the old hard cork to your bennifit. Simply cut a grove into the cork and install an AC line O ring at each end. The O ring will seal off all fuel and the cork has shrunk all it ever will...simple and effective.
