I have replaced this piping 3 times allready, its always bloated and looking like its going to pop any second. and it has popped, twice allready...

there is obviously too much fuel pressure. or no pressure is getting released. its bloated even when the car is turned off.

Anyone have any ideas ?

thanks, MG.
Are you replacing it with fuel line purchased from an auto parts store, or the correct part number from BMW? Aftermarket fuel line can be used, but it MUST be Fuel Injection rated line, not standard fuel line for carbureted cars. Normal fuel line is built to withstand 3-10 PSI, Fuel injection line around 60 PSI. Using normal fuel line on fuel injection systems is a sure route to failed lines.
