It was a FUEL HOSE

SD diesels were widely available in the US in the 1981-86 Datsun/Nissan 720 pickups, and in Canada through '87 in the D21 pickup.

"this" being the pepboys or the o'reilys stuff? or either?
Either one, but I don't think O'Reileys had all three sizes, in fact they only one size as I recall.

the store nearest me has at least 6.3 and 8 mm hoses, I didn't ask about the 3/16". the hoses are marked in SAE and metric, so if the counter kid looks at you funny for asking for 8mm just tell him to go look at the hoses :)

8mm is within (from memory) .004" of 5/16", so that's a safe interchange.

6.3mm is not found in nature on a metric car. It's just a fancy/discoursive way of saying 1/4", and not very helpful. A 1/4" line does not fit a 6mm hose barb well, but that's what we are being sold, which is a crock of shit IMO.

6mm line does exist, I've bought it at VW specialty shops, off a roll, but try to get it at a FLAPS and you're usually out of luck. Why? IDK.

i had a look at the local parts stores.mixture of gates and grommet[malaysia] and unlabelled.[australia is metric since late 60's]

they have FUEL hose marked as 8 MM [5/16] and 5/16 [8MM]
guess what there not the same ID.

the other product for sale is injector hose sold in o.5M lengths in trendy colours.It listed as 7.5mm[5/16] and fits japanese fuel lines.

the other interesting item was vacume 4mm [1/4].fits emmision hoses and fuel return pipes.
