What size to go for from Forge?

Fitted my boost gauge last weekend and realised mine are pretty shamby!

Thanks.

I've been using 3mm wall thikness with a 4mm bore from siliconehose.com and had no problems.

3mm inside diametre mate its that little bit tighter and less chance for air leaks

 

[CupraElliott]

Cheers, ordered 3mm.

Id have gone for 4mm mate as recommended by Forge

4mm for me too, had them on now over a year with none pop off what so ever

i use 4mm and had one pop off until i gave it a better dose of cable ties.

hmm I ordered some 3mm hosing to do my n249 bypass, I'm guessing it's still fine to use though

 

[Myki da Pyki]

Yeh 3mm is ok to use but 4mm is better

How does it make a difference?

 

[JIMYU]

it doesn't.

8mm for the n75 and coolant hoses... (i got mine from kelsport on ebay and its very good quality and cheap)

Cos 1mm is going to make all the differance lol!

Ive actully used 6mm on my N75 connections, i felt that 8mm would be a little sloppy around the actuator nipple and could be prone to popping off underload even clipped up. Also used 6mm on my charge pipe to n75 with what was left over. Will be ordering 8mm to do my coolent line mind.

Will be ordering 8mm to do my coolent line mind.

I've got some spare if you want it for a few quid...(its in blue tho)
