Yes I have that problem too. If you put the pump in all the way it keeps clicking off every few seconds. If I put the pump only just in, then it's not so bad, but can still give problems. I've not yet managed to fill the tank completely as I lose patience!

Funnily enough my old 145 that I had about 5 years ago never had this problem.

It sounds like pressure is building up in the tank - try checking the fuel vapour release system - I think it is related to the charcoal box which sits under the driver side wing and has blue plastic pipes back to the fuel tank.

Websites are like a**eholes, everyone has one, and im wary of any bloke trying to direct people into their's.

The world is like a ride at an amusement park. And when you choose to go on it, you think it's real because that's how powerful our minds are. And the ride goes up and down and round and round. It has thrills and chills and it's very brightly colored and it's very loud and it's fun, for a while. Some people have been on the ride for a long time, and they begin to question: Is this real, or is this just a ride? And other people have remembered, and they come back to us, they say, 'Hey - don't worry, don't be afraid, ever, because this is just a ride...' And we ... kill those people.

I had the same problem but since rewiring the relays in the Bbob it's been fine, one of them is related to the fuel vapour release system I think?

My Fuel pump kept cutting out so had a look and noticed a connection from 2 of them had corroded away!

I have the same problem with my 145.
And... one day at the Gas Station, the gas station worker said that another 145 in the neighborhood has the same problem.
It has to be filled very slowely.

The Fiat dealet mechanic said it is probably caused by a clogged vent in the gas tank.
Better to leave it this way...

I'm pretty sure the fuel tank vent is much more low tech than that.

IIRC the vapour recovery canister recycles fuel from the over-run: pumped to the fuel rail but never used.

Unless I'm getting my cars mixed up isn't the tank vent itself a crappy bit of hose from the pump assembly to somewhere in the RR wheel arch, beneath the filler cap?

Check in the manual, but if that is the case I'd whip off the liner, clean the outlet from road debris and that should do the trick...

Now that I've actually been able to drive my car for a few weeks, I get this issue when filling up. The pump cuts out frequently so it take a while to refuel.

I'm assuming this is because there is back pressure in the tank preventing the fuel flowing in quickly enough - probably caused by a blocked vent, as mentioned above.

Has anyone investigated this?

I havent.

but i have had the complete fuel tank & pipework off a FIAT coupe recently, which as far as I can tell is an identical setup.

So; I've probably got some good imagery to bring to the discussion...
