Water in Airbox

[PeeBee]

Have a duck bill rubber thingo drain in my airbox. Could fit one downstream of your tap on a small length of pipe in case you forget to close tap off crossing.

Hope she keeps hanging in there mate. Sound like u might be lucky.

Good things, but must be inspected and cleaned, often.

@mudski these Donaldson Vacuator Valves range from 25-78mm dia and the application here is for cyclonic pre filters.

The smallest (P149099 /P525956_25mm dia) looks very similar to the one in my airbox _ box is of thin wall aluminium fabricated construction and the valve is captivated by the circumferential grove shown for these two valves (Donaldson).

General info: I live on a dirt road and only ever wiped the inside of box out (installed for several yrs), never had to remove or clean the bib internal profile.

Correct. These are not originally designed for the aftermarket custom air boxes, but seem to be the best thing to use until someone else comes up with a better idea.

The difference between the two 25mm vac valves is the thickness of the panel its mated too.

FYI. If your air box fills up with water, the vac valve won't just open up, well it may a little under the weight of the water, but when not in use they sit shut. They operate when the engine is running.

the durometer is also different in those two valves . on the donaldson page it describes when to use either one .

Yeah haven't, drove back from Mallacoota, over 500k she seemed fine but think I will after Tassie trip. It's going in for a service today so will have a chat to them see what they think or if they've got time to do it. .
