Hi guys,

I've done a search but can't find the answer i'm after!

I'm about to order a couple of meters of silicon vacuum hose for, dump valve, megajolt, boostgauge etc, but am unsure what ID size to get. Can you guys recommend the correct/best size i should be using?

Cheers,

Guennie

cheers guys. so it seems that there is no set size. It's more down to personal choice.

It really depends on the stub diameter of the bits you are connecting to.

6mm is a common stub size for things like dump valves, boost control valves but not everything will be 6mm.

Check your Megajolt for example - on Megasquirt it's only a 4mm stub, Megajolt may be the same....
