What have you done today with your Austin Seven

[Douglas Alderson]

well where abouts was it showing signs of leaking in the car?

Leak was around the corner by the tap / bottom bracket.  Would prefer not to use a tank sealer and was happy to resolder but not knowing where the hole is makes fixing difficult.  Left it full of petrol over night so see what happened overnight.

Hi Douglas

It isn't the tap is it?  I've had a mysterious weeping of fuel in this area and found that petrol tends to defy gravity.  My leak was coming from the tap to tank thread and the tap itself but appeared to "stain" the whole corner of the tank.

Have you been spying on me? Checked tank this morning no leak.  The car is new to me and clearly has been leaking, my dad suggested are you sure it not an old leak which has been fixed, he has no sense of smell.  No I can definitely smell petrol and the tissue I put there are wet with petrol when in the car and carpet has petrol.  I work on other bits on the car, leave dad alone then he says you know the tap leaks, doh.  The tissue picked up the petrol and moved it back in to the car, this was while it was parked up.  So new tap, that was an easy fix.

Hi Douglas

You may not need a new tap.  I wrapped the thread between tap and tank in ptfe tape and installed a new fibre washer. Then ground the taper of the tap with a very small amount of fine grinding paste. So far it seems to have cured it but I've read others having limited success with old taps!

Howard thanks will give it a try.  Douglas
