I easily solved the problem with the lack of diesel at the pumps a few days ago.
I was standing there thinking this diesel is really cheep!
- i cant believe i just did that. I had been driving the FIAT for a month and swapped back to the Alfa after replacing the wishbones....
The 156 was almost empty and I hadnt put a lot of petrol so for any one who dose the same.
Remove the engine cover, and take the banjo of the back of the fuel filter. You need two cans a small gallon and a large one to store the fuel. put the banjo in the can and turn the ignition on. The pump in the tank will then lift the fuel into the small can. The pump only runs for ten seconds then stops you have to keep turning the ignition on and off until the tank is empty. It takes about 10 minutes to drain the tank.
Once you have all the fuel out brim (£70!!!!) the tank and you should be ok.
The system self bleeds so once the banjo has been reconnected it will be ok although you might have to spin it over a few times to get it to fire (same as when you change the fuel filter).
If you start the engine with petrol in you're stuffed!
Diesel is a lubricant and petrol a solvent chances are you will damage the injector valves and high pressure pump etc......
Since then the car has been fine, diesel and petrol mix so there is no danger of sucking just petrol through the system.
