So I'm going to be taking the plenum off of my '93 300ZX Na to change a bad injector, and I thought I might as well do the vacuum hoses and fuel hoses, as well as the plenum gasket. Looking on Z1 Motorsports, I only see 4mm, 5mm, and 6.5mm not 6mm. Will the 5mm or 6.5mm hose work for what I'm trying to do?

Unless a collector car requiring 'correct' parts use American spec hose, you will pay maybe half the price and available at all parts stores. 3/16" subs perfectly for 5 mm.

The only requirement for vac hose is that it goes on fairly easy while staying in place once installed.
