That's seems to be the norm for the perentie filler Mick. The breather pipe end goes back down towards the ground at the rear of the tank and has a bit of gauze on the end of it. You can't fill them up to the top like a civvy tank. Easiest way to stop it happening is to stop filling as soon as you hear the first gurgle as it comes up the filler neck.

Yeah both mine do it. Best result is to ignore it. By the time you pay for the fuel and come back it has stopped and no one is looking at it thinking there's a problem. Get in drive away, all good.

This just happened to me today (only the second time I have filled her up) great to know!

Thanks again guys.

its worse if the vehicle is nose up and you try to fill or you fill nose down and then park nose up...

the top of the "loop" in the vent is about 6 inches down from the top of the filler neck from memory.

if you have constant issues with a slow filling tank, get under the vehicle and clean off the gauze cover. Yes if you mount sill mounted tanks its a workable solution to T your vents off of that and then route the breather to a higher point (say through a hole drilled under the rops mount then fed up to the top of the rops inside the rops)you can also splice into the pipe on the tank side so you can use a facet pump or similar to fill the main tank from the sill tank.

Mick,


Mine does it as well. I stop filling as soon as I see diesel flowing out of the breather inside the filler. Still dribbles out a little though.
