air box blow out

[Marky]

Due to my patrol been duel fuel, it back fires through the air box every now and then. It has blown a hole through the lower part of the box, and to get a new one from nissan will cost me over $400 just for the bottom piece. Was wondering if anyone new if there was someone who made aftermarket ones? i have tried to find someone but can not. Cheers

hey Buddy.
Your best bet would be to go to the wreckers and get the base box from them. I dont and have never heared of any body who makes after market base boxes or Nissan Patrol after market boxes. But I could be wrong as I have never needed to find one.

ive rang around a few wreckers and they have told me i would be better of getting one through nissan, as it is such a commen problem they are hard to come by. If it kept doing it i thought an aluminium one would better if they made them.

Can not help with airbox,but would suggest that to prevent it happening again
that if your system is injected to replace it with a Mixer.If you do have a Mixer,
take it to a lpg specialist and have the system tuned properly.we make and
distribute lpg kits at work and though we sell them ,none of us would have
an injected system.Mixers are basic but no trouble.
My opinion only,but hope it is of some help. Cheers Peter.

Thanks mate, what is a mixer?

Basically it adds the lpg to the intake air and can be adjusted for the correct
fuel/air ratio. (No backfiring).Will talk to our tech guy tommorow and see
what he comes up with. Cheers Peter.

Gidday Marky,tech bloke reckons the cheapest and easiest way to fix
your problem is to check your ignition system.Leads and coil etc and
then to fit a backfire tube which goes before the air intake sensor.

Yea cool thanks for that ill have to get it checked out

does it only happen when you start it on gas, if so, start it on petrol, then switch to gas.
Can also be caused by pressing the accelerator when startiing (on gas).
