Autobahn 88 FMIC owners help needed
 

Im currently offshore and i have mapping booked for mid May.
I have an Autobahn 88 FMIC to fit.
I noticed that the kit does not include a silicone pipe for dump valve fitting so i need to order a pipe.
I do not know the diameter of the bits that sticks of the intercooler pipe for attaching the dump valve to. Could somebody please measurethe diameter of it for me please?
Any help would be greatly appreciated.

Think its about 1" not sure though

Anybody else? I could guess but would rather not end up with the wrong sized hose
