    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.

    Default Fuel line specs

    Ask the parts dude to check the hose roll to make sure it's high pressure spec fuel line. I got some line from NAPA rated at 150lb psi. 8 bux a foot.

    I replaced it with BMW hose. with a bmw part number. I will post the part number tommorow if u want it. its extremely expensive here. its R 160 per meter. thats about $26 per meter.

    I'm pretty possitive its the right hose. since the problem is gone.

    Thanks for the input guys, seriously.

    Mozarts_Ghost,

    Sorry to hear you're having problems with the car. Don't drive it into a lake, she's a beautifull car, who will serve you very well once she's better.

    Hope you get the problem fixed bru. My car should be sorted this weeked, I hope!


    Edit: He's right guys, here in South Africa they rape us for everything, mostly on car parts, big time! As I'm not starting to find out. Already spent R800 on my car this month. That is for oil filter, fuel filter, air filter, spark plugs, 5 liters of oil and half a tank of fuel. Then an extra 500 bucks for a new pump. Which is actually a damn good price for the pump... Merlyn BMW want R3500 for a pump!

    Default I've posted it here before but its 8mm high pressure

    fuel line and you can get a very good quality 8mm from mercedes or from Patrick at BMA for less than half of what the bmw line costs. Patrick sells mainly the mercedes line as a replacement. The line that some of you are using from autozone/checkers etc is 5/16. 5/16 is a slightly smaller diameter hose. I only use 8mm on cars that i work on.
