Hey guys I'm trying to replace the two original flexible fuel lines at the rear of the car on the driver side. Do you guys know what size these hoses are?

See the two little nylon braided hoses in the attached picture.

Also curious? Just drained my fuel tank and seemed like a good idea to replace them. I think they are 5/16" or 8mm but am not sure. If anyone could confirm that would be great!

Found the part number through EPC which when looked up says discontinued. It's 7.5mm inside diameter hose. According to pelican parts 230-476-87-26 should work as a replacement. I'll let you know if it's correct

Looks like regular braided hose. You can measure the size of the pipe it goes on.

Looks very clean down there, nice!  Anyway, I've developed a strong aversion to using the "classical" braided NBR fuel hoses in favor of modern fuel injection grade hoses with nylon lining.  Ethanol fuels and time are death so don't replace with hoses designed for 1970's fuels.  Cheers,
