Memory.
The large from the main tank to teh sump tank is 1/2" (12.5mm)
The large from the sump tank to the pump inlet is the same size.
The high pressure from the pump to the elbow in the floor is 5/16" (7.5-8.0mm).
The return in the LH corner is 10mm.
The others floating around are 8mm.
The 2 on top of the cradle, outside the boot, are 8mm, and should be included, coz many a fuel smell in an XJ-S is traced eventually to those 2 suckers.
The vent hoses at the top RH corner and up into the buttress, NO idea, I removed them and did away with that stuff, and vented the tank to the outside.
All those hoses except the HIGH pressure hose are standard fuel rated hose, BUT, I use EFI spec on all of them except the 1/2" gravity hoses, where I use standard fuel rated hose.
