Fuel lines for EA82T conversion

I'm aware the conversion to an EA82T in my L wagon requires the MPFI fuel tank and pump - but what about fuel lines? I realise the MPFI engine requires higher fuel pressure so... Will the Carb EA82 lines do the job OR should I see if I can swap the MPFI lines from the donor car; or should I get some new ones that would have to be bent to shape??? OR Could I use suitable rubber hose instead...?
Any insight would be appreciated

The std L series lines will do the trick but you might want to use the tank breather hose as the return line and switch it over down the back near the tank for the breather hose. If you dont switch it down the back as well fuel will poor out your charcoal canister.

Thanks - why would you suggest using the breather hose as the return though?

Yeah so that setup would be good enough you reckon? what did you other guys with the EA82 conversion do?

Another thing is you must replace all the neoprene lines with special high-pressure EFI fuel hose.

you don't really need to change the return line for the larger fuel pipe,
it works quite ok as is.....well just running stock boost anyway.
BTW, the breather pipe is larger, because gas takes up more volume.

Yeah cheers - I guess i'll leave it how it is - but with the neoprene hose sections replaced with heavy duty reinforced hose and see how it goes - if its a prob I can always change later - not a big job!

As long as the return line is a braided line you wont have an issue.
