I'm about to do the same thing. I'm gonna be using the same stuff that i've used off the top of my DV. I'm sure its either 7 or 9mm id.

yeah that what i was thinking but im sure it not as big as 7mm more like 4 or 5mm. I may be wrong

Sorry, no idea where i got those sizes from.

Its either 3 or 4mm.

You can use either 3mm 0r 4mm. I replaced mine with 3mm vacuum hose
