Random fuel leak...

[Kernow67]

So, just returned from a hot sandy place after a few months, and started the t350. Ran it at 1500 rpm for a while and then switched off. Then I noticed a large puddle of fuel under the rear right of the car... Nothing unusual so far I hear you say...

It was obviously coming from the fuel pump access plate, where the uptake and return pipes are located. So I cleaned it all off, and then ran the car again. You guessed it...nothing.

The hoses look fine and there is nothing seeping from either them or around the plate. Has anyone had a similar problem? I can't imagine that the tank or hoses got warm enough to expand and seal a leak, and there was a lot of fuel (half a pint maybe). Only other option I can think of is the tank vent was blocked and the tank pressurised, forcing fuel out (the tank is almost full).

Maybe I should put this down to tvr foibles and just keep an eye on it... But if anyone has seen this before, I'd be interested to hear.
