vacuum hose

[Dicko]

does anybody know the internal diameter of the vacuum hose used on a nova? im at work and about to order some silicon hose, however the company doesnt know what size I ned and im not sure.

the option is 3mm or 5mm. i guess it would be 5mm, or is it an oddball size?

[Aragorn]

internal is about 1mm for the hard plastic hoses

if u got 3mm u could prolly remove teh little rubber bit at the start of each hose and just replcae the whole lot with the silicon stuff

[Dicko]

yes its the normal hose and i swear its 5mm+ from the servo top the inlet manifold with the valve 1/2 way!!

[Ste_Nova]

bigger than 5mm for the servo vac... and it has to be hard pipe...

[Dicko]

i was told this vacuum silicon hose is ok for brakes. you saying its not then ste?

[Ste_Nova]

if it's propper stuff it will have a hard inside... normal samco is no good for servo hose as it gets sucked in

[Aragorn]

ah u never said for brake servo - i was on about the normal vacuum hose that goes to fuel pressure reg n shit like that

[Dicko]

well. its called silicon vacuum hose and its more expensive than the normal stuff, so i assume its the right stuff. They said its usualy used for brake servo connections :?

[Aragorn]

brake servo stuff is roughly 8-10mm ID by the looks of it

I can Get hold of coloured small vacuum hose..... white, red, and blue!
