910GL Posted May 24, 2020 Share Posted May 24, 2020 Swapping from carb'd EA82 to EJ. I've read that I need to upgrade the fuel lines in the process. Do I need to replace ALL of the fuel lines on the car or just the supply lines? (Are the return/evap lines ok to leave?) Thanks Brett Quote Link to comment Share on other sites More sharing options...
el_freddo Posted May 24, 2020 Share Posted May 24, 2020 All high pressure lines need to be replaced with EFI grade fuel line. If you don’t do this, you’ll burst a fuel line and have all sorts of issues that could include a fiery end. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
910GL Posted May 25, 2020 Author Share Posted May 25, 2020 (edited) Bennie, Thanks for the reply. I replaced every section of supply line with EFI grade: all the way from the tank to the intake manifold (think it was like 5 or 6 different sections). I was back there anyway swapping the fuel pump. I also replaced the return line and evap lines in the engine bay with EFI grade (just the sections from intake to firewall). There are several sections of return and evap lines back at the rear of the car that I haven't swapped. Think these are good? They shouldn't be under pressure right? My thought is to leave 'em.

el_freddo Posted May 25, 2020 Share Posted May 25, 2020 The rear return line low pressure hoses *should* be ok. Good time to swap them anyway if they’re factory units (most likely are). Cheers Bennie Quote Link to comment Share on other sites More sharing options...
