Petrol Station Blues

[Mucus]

When I fill up my MGBGT with petrol, the trigger on the fuel nozzle has to be squeezed slowly otherwise it clicks as if it has overfilled and cuts the flow. Is there a special part that goes into the filler pipe that stops this from happening or is it a case of modern pump nozzles for modern cars? The upside is I spend so long filling up, everybody else at the petrol station thinks I'm loaded!

My Triumph does this - I spend about 5 minutes finding the right position for the nozzle. Sometimes withdrawing it slightly moves it away from what must be a kink in the filler pipe, which must trigger the auto-shut-off function.

It doesn't matter what pump I use, they all seem to do it.

move the pump head around, try it in different positions.

I'd suggest a blocked (kinked?) or collapsed rubber vent hose. There should be such a hose running from the top of the fuel tank (that end will be well hidden) to the top of the filler pipe.

Have a look and get back to us - if you can remove the filler pipe end, try blowing down it... It wouldn't have been hard to fill from new .

Lol MGs aren't that advanced, it's just a big hole in the back of the car down a big pipe in to the tank! Unless you have the yank spec fuel filler anyway.

The filler pipe to the tank doesn't have any kinks or blockages, as Wildoliver says, "It's just a big hole". I wondered if there was a standard device fitted to modern cars to stop this happening.

Haha, you may well have a point - my MG is from the 1980s, with a Maxi-derived engine . My dad's Morris Marina did the stunt I refer to a few times though - it was a 9 year old me that pointed out fuel running from the filler pipe on a hot day .
