Fuel hose size?

[usajdm]

Got a leak in one of the rubber fuel lines that comes off the tank that connects to a hard line.
Anyone know the diameter hose I need?
Its an 89 coupe.... not sure if the lines are different sizes, but I know the set-ups are different between the coupes and fast-backs.
Im headed to the car now and will check which of the three lines(outlet, return or evaporation) it is.
Hopefully that dosent matter.

Thanks alot!

You can just take the hose to an auto parts store and have them match up the size right on site. That is how I would go about it.

You know this how? They're not different. Exactly the same.

Wow........... let me guess, you have your own personal seat on the band-wagon dont you?

Anyhow, the differences I was refering to include some of the piping and the absent reservoir tank on the coupe.
So come on.... dont be such a d!(k.
I was trying to give as much info as I could, in order to get a useful answer.
Something that some people were able to provide.
Thankyou for that help.

Reservoir, as in the coolant? Or something else?

Both fastback and coupes are IDENTICAL in every way from the drivetrain to the fuel system. Engine, transmission, hoses, wiring, piping, canisters, everything is exactly the same.
Don't assume because you've seen one car missing a lot of shit that they're all like that.
